Product Description

 

Product Description

JR148-8 310KW 320KW 380KW Wound Rotor Slip Ring Induction Motor comply with the specifications of JB563, JB564-64 technical conditions. It can drive a variety of different types of machinery, such as crushers, ball mills, fans, compressors, water pumps, cutting machines, transportation machinery and other equipment, which can be used as prime mover in coal mines, machinery industries, power plants and various industrial and mining enterprises, suitable for small power grid capacity or places where the required starting torque is large to improve starting performance.

The JR series ball mill motor mounting type is horizontal mounting with base and foot. All types of motors can be coupled to the driven machinery using a coupling. The structure of the wound rotor slip ring motor is a bi-symmetrical radial ventilation system. The cooled air enters from the air inlet of the end covers on both sides. Part of the cooled air passes through the fan or wind blade on the rotor of the motor blowing through the end part of the stator coil, and the other part passes through the radial ventilation slot in the rotor core, and then is discharged by the outlet on the side of the frame.
