Overview:

JR series motor is wound rotor three-phase asynchronous motor. It meet the standard of JB 564-64 technical requirements. JR series must insert starting rheostat in rotor circuit in advance, and can’t be started directly by short circuiting the rotor winding. The basic mounting mode of this type is horizontal installation with bottom foot. It should be connected with the driven machine by coupler device. JR motor adopted a double - sided radial ventilation system and antifriction bearing. By the side of shaft extension end, the outlet box is on the right of the frame. It can be reduced power running for long time in condition of Reduce the torque.

Applications:

Ventilator, compressor, water pump, crusher, ball mill, stock-removing machine, transport machine and other machinery.

It can be prime mover of industries like coal mine, mechanical industry,  power station and different kinds of manufacturing and mining industries.

Working Conditions:

Altitude: less than 1000 meters,

Max Temperature 40℃

Minimum Temperature 0℃

Clean, Acid-Free, alkali-free or there is no other corrosive gas in the working place.

* JR motor can not work in environment of explosive gas or many dust.

* When the temperature is out of the specialized range, it should adopt Pipeline ventilation mode.
