YZR Slip ring motors

YZR and YZ series motors are suitable for driving various lifting machinery and metallurgical auxiliary equipment. They have high overload capacity and mechanical strength. They are especially suitable for short-term or intermittent operation, frequent starting and braking, and significant vibration and impact. device of.
The motor has good sealing performance. The protection level of the motor used in general places is IP44, and the protection level of the motor used in metallurgical places is IP54. The YZR series is a three-phase asynchronous motor with a wound rotor, and the YZ series is a three-phase asynchronous motor with a squirrel cage rotor. .
The insulation grades of motors are divided into two types: F class and H class. Class F is suitable for general places where the cooling medium temperature does not exceed 40℃; Class H is suitable for metallurgical places where the cooling medium temperature does not exceed 60℃. The two motors have the same parameters.
Power: 10kw-600kw 
Protection level
The protection grade of the metallurgical motor shell is IP54; the protection grade of the lifting motor shell is IP44
cooling method
Frame 112-132 IC0041 Frame 160-355 IC0141 Frame 400 IC0151
Insulation level
The insulation grade of metallurgical motors is H class, and the insulation grade of lifting motors is F class.
Junction Box
The motor stator junction box is located on the top of the frame and can be connected from either side of the frame.
transfer method
The motor adopts coupling or gear transmission. When spur gear transmission is used, the gear pitch circle diameter should not be less than twice the shaft extension diameter.
