JZ,JZR,YZ and YZR series are electric motors for hoister and metallurgical machines. - details see: https://www.machineto.com/yzr-series-three-phase-asynchronous-hoisting-metallurgical-motors-10237037

YZ & YZR series three-phase asynchronous motors are new series products designed unitedly in China for hoisters and metallurgical machines. Compared with aeries JZ2 and JZR2, they have increased their efficiency by 1.88%, output by 9.35%, and starting torque slightly. The rating class and mounting dimensions comply with the requirements of IEC72 standard, which are in favor of the export trade and interchange in corresponding motor for the import equipment.

The rated voltage is 380V, the rated frequency is 50Hz, the basic duty type is S3, the basic CDF is 40%, 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 an 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. There are two cooling forms:IC410 for frame size ranging from 112 to 132 and IC411 for frame size ranging from 160 to 355. Star connection is adopted in stator winding for those motors whose powers are no more than 132 kw.

The rotor of motor of series YZR is of wound type, whereas that of series YZ is of squirrel cage type.

These motors are suited for power drive for the hoisters and other similar equipment, short time running duty type S2 or international periodic duty type S3, starting and braking frequently, and the equipment having obvious impact and vibration.
