JR slip ring induction motor has a large capacity, can provide a larger starting torque under a small starting current, and can be added to the rotor loop to add external resistance to change the characteristics of the speed. Therefore, JR three phase induction motor could be selected when the squirrel cage rotor motor cannot start smoothly.
Type: JR slip ring induction motor
Speed: 4/6/8/10/12 poles
Insulation class: B
Protection class: IP21
Mounted type: B3
The basic installation type of JR slip ring induction motor is horizontal installation with feet on the base, and the electric motor can be connected with the driven machinery by a coupling. The motor adopts a symmetrical radial ventilation system on both sides. The cooling air enters from the air inlets of the end covers on both sides.
The bearing adopts rolling bearing. The motor is equipped with a slip ring. The slip ring is installed on the side of the NDE side. All are brush less lifting and short-circuiting devices. The brush model is J201.
