Product Details

JR series wound rotor slip ring three phase asynchronous motor (IP23)

IGeneral introduction

JR series electric motor can drive a variety of machinery, such as: fans ,compressors ,water pumps ,crushers,ball mills ,cutting tools ,transportation machinery and other equipment ,also is available to coal mining, machinery industry ,power, plants and various industrial and mining enterprises as the prime mover.JR series is wound rotor three-phase asynchronous motors JR series motors comply with JB564-64 technical conditions.

This series motor is protected motor,can also be made to pipeline ventilated according to user needs.Motor location should be no more than 1000meters altitude ,ambient air temperature does not exceed +40°C,not less than 0°C,clean,free of acid and other corrosive gasses of indoor air.Motors are not allowed work in the presence of explosive gas or dust environment.When the ambient air temperature exceeds the above requirements or air is dirty ,ventilation pipes should be used.In this case , the temperature of through the both ends of the motor cooling air should be 0°C~+40°C, and should ensure that the air pressure inside the duct and motor is higher than the ambient air pressure ,when necessary,to install a blower,dust and etc.When starting must be pre-accessed starting rheostat in the rotor circuit . Do not allow start the rotor winding directly .

IIThe structure introduction :

The basic installation type is base with foot horizontal installation, all types of motor can adopt coupling connected with driven mechanical.Motor is with radial symmetry on both sides of the ventilation system.Cooling air enter from both sides end covers air inlet. Some of cooling air through the fan on the motor rotor or by the wind vane to the terminal connection of stator coil . Another part of the air through the radial ventilation slot in the rotor core ,then out from the frame side vents . Pipeline ventilated motor ventilation system is same as above .The bearings of otor adopts rolling bearings ,the bearing grease grades for lithium grease ZL-3 rom the motor haft xtension end , the outlet box on the right side of the frame .JR series motor allows long term eceleration operation ,at torque reduced conditions.At this time ,allowing the correspondence etween power and torque and speed output should be in accordance with rules.

IIIThe meaning of motor type

JR -115 -6

JR——Wound Rotor asynchronous motor

11——Center height of frame

5Core Length

6——Pole number

JR series motor has two types :brusher lifting and short-circuiting device and without brusher lifting and short-circuiting device .
