YB2 YB3 0.55-315KW Three phase electric motor Explosion proof motor

YBD2 sequence Two speed flameproof three phase asynchronous motor is developed on the basis of YB2 series flameproof motors.It uses the simplex winding polarity reversal technique to recognize the pace transformation. Different poles supply relative pace. YBD2 series motor are suited for mechanical equipments which needed pace regulation, mainly utilised in coal,oil and all-natural gasoline,petrochemical and chemical industries,typically utilized to generate pumps,followers,compressors and other transmission machinery. YBD2 series motor could marked as Exd I,Exd II AT4 or Exd II BT4. Exd I is utilized in the non excavation doing work issue and coal mine with methane or coal dust,Exd II AT4 and Exd II BT4 are applied in the situation of explosion proof gasoline compound with Manufacturing facility II type,Quality A&B, temperature T1,T2,T3 and T4.

The overall performance of the security of the merchandise is confirming to the common of GB3836.1-2000<> and GB3836.two-2000<>,This ranges of goods are suited for the non-mining working region in underground mine or where there are the explosive gasoline combination in factories.


Work conditions


Temperature and Insulation

The Maters’ insulation method are made by Class F(155ºC), operated with Class B(80K). Which incerase the motor valuable existence and dependability.

Cooling and air flow

The common cooling technique is absolutely Enclosed Fan Cooled (TEFC) it accordance with IC411 of IEC60034-6. CZPT motors are outfitted with radialflow plastic supporters

Protection class

The standard levels of security is IP55. The IP55 enclosure indicates complete hoseproof and dustproof protection .A larger levels of safety is CZPT

Motor safety

Motors can be installed with PTC, PT100, such as winding and bearing temperature measurement as properly as other sorts of defense on ask for.

Voltage and frequency

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


YB2 motors are made to vibration course A, vibration course B is CZPT on request.
