Product Description

The JR series motor is a protective winding type rotor three-phase asynchronous motor with cooling method IC01 and continuous working system (S1). This series of motors can provide a large starting torque at a small starting current and can adjust the speed within a certain range.
The JR winding slip ring motor casing is a cast iron casing or a steel plate welded casing with high structural strength and good mechanical properties. The motor shaft extension end and the non-bearing end have an inlet and outlet air outlet, and the motor slip ring is located at the non-bearing end. The series of motors have simple structure, convenient installation, convenient maintenance, large starting torque and safe and reliable operation. JR winding slip ring motors can drive a variety of different machines, such as fans, compressors, pumps, crushers, ball mills, winches, hoists, transport machinery and other equipment, as well as mines, machinery, power plants and Used as prime mover in various industrial and mining enterprises.
