Wound Rotor Slip Ring Motor

Wound Rotor Slip Ring Motor
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.
The JR series motor is a wound rotor three-phase asynchronous motor. This
series of motors meets the technical standard conditions. It can drive a
variety of different machines, such as fans, compressors, pumps, crushers, ball
mills, cutting machines, transport machinery and other equipment. It is used as
a prime mover in the machinery industry, power plants and various industrial
and mining enterprises. The rating of the JR winding slip ring motor is based
on the continuous working system (S1). The frequency is 50HZ, the rated voltage
is 220V/380V, 380V, 415V, 3000V, 6000V, which can be designed to 3300V/10000V
according to the needs of users.
The protection of this series of motors is IP23; the cooling method is IC01;
the structure and installation method of the motor is generally IMB3, and it
can also be designed as vertical installation according to customer
requirements.
The ratio of the maximum torque to the rated torque of the JR winding slip ring
motor at rated voltage is not less than 1.8.
The JR winding slip ring motor must be connected to the starting varistor in
the rotor circuit at the start. It is not permissible to short-circuit the
rotor windings directly.
