YZR/YZ Type Motors Apply To
YZ, YZR series of motors for driving various types of lifting machinery, metallurgical machinery and other similar equipment, special products, with a large overload capacity and high mechanical strength. So it is particularly suitable for those short-term or intermittent operation, frequent start, brake, sometimes overload and have significant vibration and shock equipment.
The power rating and mounting dimensions of the motor are in accordance with the International Electrotechnical Commission (IEC) standard, and the correspondence is the same as that of the German DIN42681 and Japan JEM1202. The insulation class of the motor is F and H. F class for the ambient air temperature does not exceed 40 ℃ general place; H level for the ambient temperature does not exceed 60 ℃ metallurgical sites. The two motors have the same parameters.
For the general place of the motor protection class IP44, for metallurgical places of the motor protection class IP54.
YZ series motor for the cage rotor motor, YZR series motor for the winding rotor motor.
Y is representative of asynchronous, Z is representative of lifting, and R is wound rotor. The difference is that the rotor is different. YZR series is the winding rotor motor.
