product:Slip Ring Low Voltage Motor: JR Series Electric Motor
Feature and usage
JR series of winding three-phase asynchronous motor for the old series of motors, electromagnetic calculating the insurance coefficient, strong overload capacity.
JR series motor using total pressure rotor resistor string starts with a startup current, starting torque, and efficiency, low noise, little vibration, ventilation performance, reliable operation and easy installation and
maintenance advantages.
JR Series motors widely used to drive a variety of general machinery such as re-rolling mill,cement mill,steel mill ,compressors,pumps, brake, lifting machine and other mechanical transmission equipment, ball mill, blowers,pumps and wire drawing machines and other machinery and euipment.
