YZR series winding rotor three-phase asynchronous hoist motors are for hoisting and metallurgical machines and other similar equipments. With great load capacity and mechanical strength, they are suitable for equipment with short time or intermittent duty, frequency start or brake, obvious shock and impact.

The standard range of power output and mounting dimensions are in complying with the recommended standard of IEC 72. The motor can work well when the altitude does not exceed 1000 meters.

The motors posses a better enclosure, degree of protection IP44 for normal site condition and IP54 from metallurgical condition.


There are two classes of F and H insulation, Class F is applicable to suit temperature which cool air does not exceed 40 under normal condition, Class H is suitable for metallurgical sites when ambient temperature no exceeding 60 both motors have same data.


Specific: 

The rated voltage is 380V, the rated frequency is 50Hz and the degree of protection by enclosure for general environment is IP44, whereas that for metallurgical environment is IP54.  There are two kinds of insulation class, that is, F and H.  Class F is suitable for general place where it is not more than 40°C and class H is suitable for metallurgical environment where it is not more than 60°C. The two kinds of motors are the same in parameters. 


Application:

These motors are suited for power drive for the hoisters and other similar equipment, international periodic duty type S3, starting and braking frequently, and the equipment having obvious impact and vibration.
