YZR series lifting and metallurgical wound rotor three-phase asynchronous motor
YZR series lifting and metallurgical wound rotor three-phase asynchronous motors are used for electric drive of various types of lifting machinery, metallurgical auxiliary equipment and other similar equipment, with high overload capacity and mechanical strength, suitable for short-term or Equipment with significant vibration and shock, such as intermittent periodic work, frequent starting, and braking. The product complies with the requirements of the JB/T10105-1999 standard. Its mounting dimensions and power ratings are in accordance with IEC72 recommendations, similar to JEM1202 in Japan and DIN42681 in Germany, and are mostly interchangeable.
The insulation grade of the motor is divided into F and H grades. Class F insulated motors are generally used for lifting. They are suitable for general use where the ambient temperature does not exceed 40 ° C. Class H insulated motors are used for metallurgy and are suitable for metallurgical applications where the ambient temperature does not exceed 60 ° C.
The working system of the electric motor is divided into a short-time working system S2 and a discontinuous period working system S3. The reference work of the motor is S3, and the reference load duration is 40%. The motor can also work in S4, S5 and other working systems.
