0.75KW-315kw Three Phase AC Explosion Proof Flame proof  Asynchronous Electric Motor with CE

YBD2 collection Two pace flameproof a few phase asynchronous motor is created on the basis of YB2 sequence flameproof motors.It uses the simplex winding polarity reversal technique to realize the speed transformation. Different poles supply relative velocity. YBD2 series motor are suitable for mechanical equipments which needed velocity regulation, mostly utilized in coal,oil and organic fuel,petrochemical and chemical industries,usually utilised to generate pumps,enthusiasts,compressors and other transmission equipment. YBD2 collection motor could marked as Exd I,Exd II AT4 or Exd II BT4. Exd I is used in the non excavation operating situation and coal mine with methane or coal dust,Exd II AT4 and Exd II BT4 are utilized in the condition of explosion proof gasoline compound with Manufacturing facility II type,Grade A&B, temperature T1,T2,T3 and T4.

There are E x d I and ExdIIBT4 sort in YB2 ranges of  three-stage asynchronous explosion proof motor according to the prerequisite of the software. The overall performance of the safety of the merchandise is confirming to the normal of GB3836.one-2000<> and GB3836.2-2000<>,This ranges of goods are suited for the non-mining functioning area in underground mine or in which there are the explosive gas combination in factories.


Work conditions


Temperature and Insulation

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

Cooling and ventilation

The normal cooling method is totally Enclosed Supporter Cooled (TEFC) it accordance with IC411 of IEC60034-6. CZPT motors are outfitted with radialflow plastic followers

Protection class

The normal levels of safety is IP55. The IP55 enclosure means comprehensive hoseproof and dustproof security .A greater degrees of security is CZPT

Motor defense

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

Voltage and frequency

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


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

Terminal box location

Terminal box at the top  of motor frame 

Good quality assurance

Stringent top quality methods are observed from 1st design and style to finished products in accordance with CZPT documented good quality system.
