YBF2 Series Flame-proof Three phase Asynchronous Electric Motor for Fan Blower

YBF2 Series Flame-proof Three phase Asynchronous Electric Motor for Fan Blower

YBF2 collection flameproof 3 section asynchronous motor for enthusiast/Blower is specifically created for flameproof fan, which primarily utilized at areas these kinds of as coal mines, petrochemical business and chemical sector, where the ambiance could include flammable gases. YB2 sequence motors have the characteristics of higher efficiency, basic safety and dependable, minimal noise etc. The flameproof performance of YBF2 series motors are comply with Chinese Nationwide CZPT GB3836.12571 , and GB3836.two-2571 , also comply with IEC 60571& IEC 60571. We source YBF2 sequence motors with Ex marking Exdl, ExdII AT4 and ExdII BT4, ExdI is intended for mines the place the environment, in addition to firedamp, may possibly incorporate significant proportions of other flammable gases Although ExdII AT4 and ExdII BT4 are meant for use in spots with an explosive gas atmosphere other than mines prone to firedamp, A denotes a common gasoline is propane, B signifies a common gas is ethylene, and the atmosphere temperature is T1,T2, T3, T4.

There are E x d I and ExdIIBT4 type in YB2 ranges of  3-period asynchronous explosion evidence motor according to the requirement of the software. The overall performance of the protection of the products is confirming to the standard of GB3836.one-2000<> and GB3836.two-2000<>,This ranges of products are suited for the non-mining operating location in underground mine or the place there are the explosive gas combination in factories.


Work conditions


Temperature and Insulation

The Maters’ insulation technique are designed by Course F(155ºC), operated with Course B(80K). Which incerase the motor valuable lifestyle and dependability.

Cooling and air flow

The normal cooling method is entirely Enclosed Enthusiast Cooled (TEFC) it accordance with IC411 of IEC60034-six. CZPT motors are outfitted with radialflow plastic enthusiasts

Safety course

The standard degrees of safety is IP55. The IP55 enclosure indicates comprehensive hoseproof and dustproof protection .A higher levels of safety is CZPT

Motor protection

Motors can be put in with PTC, PT100, this kind of as winding and bearing temperature measurement as nicely as other sorts of security on request.

Voltage and frequency

CZPT voltage and frequency are 380V 50HZ, and can be wound for any single voltage it the selection 200-660V at a frequency 50hz. The motors will work satisfactorily with variants of ±5% from the rated voltage.


YB2 motors are designed to vibration course A, vibration class B is CZPT on ask for.
