What Is a Gear Motor?

A gear motor is an electric motor coupled with a gear train. It uses either DC or AC power to achieve its purpose. The primary benefit of a gear reducer is its ability to multiply torque while maintaining a compact size. The trade-off of this additional torque comes in the form of a reduced output shaft speed and overall efficiency. However, proper gear technology and ratios provide optimum output and speed profiles. This type of motor unlocks the full potential of OEM equipment.

Inertial load

Inertial load on a gear motor is the amount of force a rotating device produces due to its inverse square relationship with its inertia. The greater the inertia, the less torque can be produced by the gear motor. However, if the inertia is too high, it can cause problems with positioning, settling time, and controlling torque and velocity. Gear ratios should be selected for optimal power transfer.
The duration of acceleration and braking time of a gear motor depends on the type of driven load. An inertia load requires longer acceleration time whereas a friction load requires breakaway torque to start the load and maintain it at its desired speed. Too short a time period can cause excessive gear loading and may result in damaged gears. A safe approach is to disconnect the load when power is disconnected to prevent inertia from driving back through the output shaft.
Inertia is a fundamental concept in the design of motors and drive systems. The ratio of mass and inertia of a load to a motor determines how well the motor can control its speed during acceleration or deceleration. The mass moment of inertia, also called rotational inertia, is dependent on the mass, geometry, and center of mass of an object.


There are many applications of gear motors. They provide a powerful yet efficient means of speed and torque control. They can be either AC or DC, and the two most common motor types are the three-phase asynchronous and the permanent magnet synchronous servomotor. The type of motor used for a given application will determine its cost, reliability, and complexity. Gear motors are typically used in applications where high torque is required and space or power constraints are significant.
There are two types of gear motors. Depending on the ratio, each gear has an output shaft and an input shaft. Gear motors use hydraulic pressure to produce torque. The pressure builds on one side of the motor until it generates enough torque to power a rotating load. This type of motors is not recommended for applications where load reversals occur, as the holding torque will diminish with age and shaft vibration. However, it can be used for precision applications.

It is important to note that the report contains segment-specific information, so that readers can easily understand the market potential of the geared motors market.


The safety factor, or SF, of a gear motor is an important consideration when selecting one for a particular application. It compensates for the stresses placed on the gearing and enables it to run at maximum efficiency. Manufacturers provide tables detailing typical applications, with multiplication factors for duty. A gear motor with a SF of three or more is suitable for difficult applications, while a gearmotor with a SF of one or two is suitable for relatively easy applications.
The global gear motor market is highly fragmented, with numerous small players catering to various end-use industries.

A gear motor is an electric motor that is paired with a gear train. They are available in AC or DC power systems. Compared to conventional motors, gear reducers can maximize torque while maintaining compact dimensions. But the trade-off is the reduced output shaft speed and overall efficiency. However, when used correctly, a gear motor can produce optimal output and mechanical fit. To understand how a gear motor works, let’s look at two types: right-angle geared motors and inline geared motors. The first two types are usually used in automation equipment and in agricultural and medical applications. The latter type is designed for rugged applications.
In addition to its efficiency, DC gear motors are space-saving and have low energy consumption. They can be used in a number of applications including money counters and printers. Automatic window machines and curtains, glass curtain walls, and banknote vending machines are some of the other major applications of these motors. They can cost up to 10 horsepower, which is a lot for an industrial machine. However, these are not all-out expensive.
Electric gear motors are versatile and widely used. However, they do not work well in applications requiring high shaft speed and torque. Examples of these include conveyor drives, frozen beverage machines, and medical tools. These applications require high shaft speed, so gear motors are not ideal for these applications. However, if noise and other problems are not a concern, a motor-only solution may be the better choice. This way, you can use a single motor for multiple applications.


Geared motors are among the most common equipment used for drive trains. Proper maintenance can prevent damage and maximize their efficiency. A guide to gear motor maintenance is available from WEG. To prevent further damage, follow these maintenance steps:
Regularly check electrical connections. Check for loose connections and torque them to the recommended values. Also, check the contacts and relays to make sure they are not tangled or damaged. Check the environment around the gear motor to prevent dust from clogging the passageway of electric current. A proper maintenance plan will help you identify problems and extend their life. The manual will also tell you about any problems with the gearmotor. However, this is not enough – it is important to check the condition of the gearbox and its parts.
Conduct visual inspection. The purpose of visual inspection is to note any irregularities that may indicate possible problems with the gear motor. A dirty motor may be an indication of a rough environment and a lot of problems. You can also perform a smell test. If you can smell a burned odor coming from the windings, there may be an overheating problem. Overheating can cause the windings to burn and damage.
Reactive maintenance is the most common method of motor maintenance. In this type of maintenance, you only perform repairs if the motor stops working due to a malfunction. Regular inspection is necessary to avoid unexpected motor failures. By using a logbook to document motor operations, you can determine when it is time to replace the gear motor. In contrast to preventive maintenance, reactive maintenance requires no regular tests or services. However, it is recommended to perform inspections every six months.

The Basics of a Gear Motor

The basic mechanism behind the gear motor is the principle of conservation of angular momentum. The smaller the gear, the more RPM it covers and the larger the gear, the more torque it produces. The ratio of angular velocity of two gears is called the gear ratio. Moreover, the same principle applies to multiple gears. This means that the direction of rotation of each adjacent gear is always the opposite of the one it is attached to.

Induction worm gear motor

If you’re looking for an electric motor that can deliver high torque, an Induction worm gear motor might be the right choice. This type of motor utilizes a worm gear attached to the motor to rotate a main gear. Because this type of motor is more efficient than other types of motors, it can be used in applications requiring massive reduction ratios, as it is able to provide more torque at a lower speed.
The worm gear motor is designed with a spiral shaft that is set into splines in another gear. The speed at which the worm gear rotates is dependent on the torque produced by the main gear. Induction worm gear motors are best suited for use in low-voltage applications such as electric cars, renewable energy systems, and industrial equipment. They come with a wide range of power-supply options, including twelve-volt, 24-volt, and 36-volt AC power supplies.
These types of motors can be used in many industrial settings, including elevators, airport equipment, food packaging facilities, and more. They also produce less noise than other types of motors, which makes them a popular choice for manufacturers with limited space. The efficiency of worm gearmotors makes them an excellent choice for applications where noise is an issue. Induction worm gear motors can be compact and extremely high-torque.
While the Induction worm gear motor is most widely used in industrial applications, there are other kinds of gearmotors available. Some types are more efficient than others, and some are more expensive than others. For your application, choosing the correct motor and gearbox combination is crucial to achieving the desired result. You’ll find that the Induction worm gear motor is an excellent choice for many applications. The benefits of an Induction worm gear motor can’t be overstated.
The DC gear motor is an excellent choice for high-end industrial applications. This type of gearmotor is smaller and lighter than a standard AC motor and can deliver up to 200 watts of torque. A gear ratio of three to two can be found in these motors, which makes them ideal for a wide range of applications. A high-quality DC gear motor is a great choice for many industrial applications, as they can be highly efficient and provide a high level of reliability.
Electric gear motors are a versatile and widely used type of electric motor. Nevertheless, there are some applications that don’t benefit from them, such as applications with high shaft speed and low torque. Applications such as fan motors, pump and scanning machines are examples of such high-speed and high-torque demands. The most important consideration when choosing a gearmotor is its efficiency. Choosing the right size will ensure the motor runs efficiently at peak efficiency and will last for years.

The nodular cast iron housing helps make the unit robust in difficult environments, while the precision-machined gears provide quiet, vibration-free operation. These motors are available in double reduction, triple reduction, and quadruple reduction. The capacity ranges from 0.12 kW to 45 kW. You can choose from a wide variety of capacities, depending on the size of your gearing needs.
The SEW-EURODRIVE parallel shaft helical gearmotor is a convenient solution for space-constrained applications. The machine’s modular design allows for easy mounting and a wide range of ambient temperatures. They are ideal for a variety of mechanical applications, including conveyors, augers, and more. If you want a small footprint, the SEW-EURODRIVE parallel shaft helical gear motor is the best solution for you.
The parallel shaft helical gears are advantageous for both high and low speed applications. Parallel helical gears are also suitable for low speed and low duty applications. A good example of a cross-helix gear is the oil pump of an internal combustion engine. Both types of helical gears are highly reliable and offer vibration-free operation. They are more costly than conventional gear motors, but offer more durability and efficiency.

Their combined power output is 100 Nm, and they have a high efficiency of up to 90%. For more information about the helical gear motor, contact a Heidrive representative.
A helical gear unit can be classified by its reference section in the standard plane or the turning plane. Its center gap is the same as that of a spur gear, and its number of teeth is the same. In addition to this, the helical gear has a low axial thrust, which is another important characteristic. The helical gear unit is more efficient at transferring torque than a spur gear, and it is quieter, too.
These units are designed to handle large loads. Whether you are using them for conveyors, augers, or for any other application that involves high-speed motion, a helical gear unit will deliver maximum performance. A helical gear unit from Flender can handle 400,000 tasks with a high degree of reliability. Its high efficiency and high resistance to load ensures high plant availability.

The Benefits of Using a Gear Motor

A gear motor works on the principle of conservation of angular momentum. As the smaller gear covers more RPM and the larger gear produces more torque, the ratio between the two is greater than one. Similarly, a multiple gear motor follows the principle of energy conservation, with the direction of rotation always opposite to the one that is adjacent to it. It’s easy to understand the concept behind gear motors and the various types available. Read on to learn about the different types of gears and their applications.

Electric motor

The choice of an electric motor for gear motor is largely dependent on the application. There are various motor and gearhead combinations available, and some are more efficient than others. However, it is critical to understand the application requirements and select a motor that meets these needs. In this article, we’ll examine some of the benefits of using a gear motor. The pros and cons of each type are briefly discussed. You can buy new gear motors at competitive prices, but they aren’t the most reliable or durable option for your application.
To determine which motor is best for your application, you’ll need to consider the load and speed requirements. A gear motor’s efficiency (e) can be calculated by taking the input and output values and calculating their relation. On the graph below, the input (T) and output (P) values are represented as dashed lines. The input (I) value is represented as the torque applied to the motor shaft. The output (P) is the amount of mechanical energy converted. A DC gear motor is 70% efficient at 3.75 lb-in / 2,100 rpm.
In addition to the worm gear motor, you can also choose a compact DC worm gear motor with a variable gear ratio from 7.5 to 80. It has a range of options and can be custom-made for your specific application. The 3-phase AC gear motor, on the other hand, works at a rated power of one hp and torque of 1.143.2 kg-m. The output voltage is typically 220V.
Another important factor is the output shaft orientation. There are two main orientations for gearmotors: in-line and offset. In-line output shafts are most ideal for applications with high torque and short reduction ratios. If you want to avoid backlash, choose a right angle output shaft. An offset shaft can cause the output shaft to become excessively hot. If the output shaft is angled at a certain angle, it may be too large or too small.

Gear reducer

A gear reducer is a special kind of speed reducing motor, usually used in large machinery, such as compressors. These reducers have no cooling fan and are not designed to handle heavy loads. Different purposes require different service factors. For instance, a machine that requires frequent fast accelerations and occasional load spikes needs a gear reducer with a high service factor. A gear reducer that’s designed for long production shifts should be larger than a machine that uses it for short periods of time.
A gear reducer can reduce the speed of a motor by a factor of two. The reduction ratio changes the rotation speed of the receiving member. This change in speed is often required to solve problems of inertia mismatch. The torque density of a gear reducer is measured in newton meters and will depend on the motor used. The first criterion is the configuration of the input and output shafts. A gear ratio of 2:1, for example, means that the output speed has been cut in half.
Bevel gear reducers are a good option if the input and output shafts are perpendicular. This type is very robust and is perfect for situations where the angle between two axes is small. However, bevel gear reducers are expensive and require constant maintenance. They are usually used in heavy-duty conveyors and farm equipment. The correct choice of gear reducer for gear motor is crucial for the efficiency and reliability of the mechanism. To get the best gear reducer for your application, talk to a qualified manufacturer today.
Choosing a gear reducer for a gear motor can be tricky. The wrong one can ruin an entire machine, so it’s important to know the specifics. You must know the torque and speed requirements and choose a motor with the appropriate ratio. A gear reducer should also be compatible with the motor it’s intended for. In some cases, a smaller motor with a gear reducer will work better than a larger one.

Motor shaft

Proper alignment of the motor shaft can greatly improve the performance and life span of rotating devices. The proper alignment of motors and driven instruments enhances the transfer of energy from the motor to the instrument. Incorrect alignment leads to additional noise and vibration. It may also lead to premature failure of couplings and bearings. Misalignment also results in increased shaft and coupling temperatures. Hence, proper alignment is critical to improve the efficiency of the driven instrument.
When choosing the correct type of gear train for your motor, you need to consider its energy efficiency and the torque it can handle. A helical geared motor is more efficient for high output torque applications. Depending on the required speed and torque, you can choose between an in-line and a parallel helical geared motor. Both types of gears have their advantages and disadvantages. Spur gears are widespread. They are toothed and run parallel to the motor shaft.
A planetary gear motor can also have a linear output shaft. A stepping motor should not operate at too high current to prevent demagnetization, which will lead to step loss or torque drop. Ensure that the motor and gearbox output shafts are protected from external impacts. If the motor and gearbox are not protected against bumps, they may cause thread defects. Make sure that the motor shafts and rotors are protected from external impacts.
When choosing a metal for your gear motor’s motor shaft, you should consider the cost of hot-rolled bar stock. Its outer layers are more difficult to machine. This type of material contains residual stresses and other problems that make it difficult to machine. For these applications, you should choose a high-strength steel with hard outer layers. This type of steel is cheaper, but it also has size considerations. It’s best to test each material first to determine which one suits your needs.
In addition to reducing the speed of your device, a geared motor also minimizes the torque generated by your machine. It can be used with both AC and DC power. A high-quality gear motor is vital for stirring mechanisms and conveyor belts. However, you should choose a geared motor that uses high-grade gears and provides maximum efficiency. There are many types of planetary gear motors and gears on the market, and it’s important to choose the right one.

First stage gears

The first stage gears of a gear motor are the most important components of the entire device. The motor’s power transmission is 90% efficient, but there are many factors that can affect its performance. The gear ratios used should be high enough to handle the load, but not too high that they are limiting the motor’s speed. A gear motor should also have a healthy safety factor, and the lubricant must be sufficient to overcome any of these factors.
The transmission torque of the gear changes with its speed. The transmission torque at the input side of the gear decreases, transferring a small torque to the output side. The number of teeth and the pitch circle diameters can be used to calculate the torque. The first stage gears of gear motors can be categorized as spur gears, helical gears, or worm gears. These three types of gears have different torque capacities.
The first stage helical gear is the most important part of a gear motor. Its function is to transfer rotation from one gear to the other. Its output is the gearhead. The second stage gears are connected by a carrier. They work in tandem with the first stage gear to provide the output of the gearhead. Moreover, the first stage carrier rotates in the same direction as the input pinion.
Another important component is the output torque of the gearmotor. When choosing a gearmotor, consider the starting torque, running torque, output speed, overhung and shock loads, duty cycles, and more. It is crucial to choose a gearmotor with the right ratio for the application. By choosing the proper gearmotor, you will get maximum performance with minimal operating costs and increase plant productivity. For more information on first stage gears, check out our blog.
The first stage of a gear motor is composed of a set of fixed and rotating sprockets. The first stage of these gears acts as a drive gear. Its rotational mass is a limiting factor for torque. The second stage consists of a rotating shaft. This shaft rotates in the direction of the torque axis. It is also the limiting force for the motor’s torque.
