Product Description

YZR/YZ Series Induction Motors for Cranes and Metallurgical Applications

YZR and YZ series wound rotor and squirrel-cage rotor three-phase asynchronous motor for lifting and metallurgy is suitable for the power drive of the lifting machine and other similar equipment, with high overload capability and mechanical strength, and it is also suitable for short-time or intermittent character of service, the equipment with frequent starting, braking and obvious shock and impact.

The power grade and the installation dimensions of the motor are in accordance with the recommended standard of IEC 72; the correlation between the power grade and the installation dimensions is similar with Japan JEM1202 and Germany DIN42681, most of which can be exchanged. YZR series wound rotor three-phase asynchronous motor for metallurgy and lifting is in accordance with the specification of professional standard JB/T10105-1999 and YZ series squirrel-cage rotor three-phase asynchronous motor for metallurgy and lifting is in accordance with the professional standard.

The motor can run normally when the elevation not more than 1000m. The environment temperature for class F is from -20 to 40 Celsius degree，for H class from -20 to 60 Celsius degree. Relative humidity less 90%.
