product description

1.1. YZR and YZ series are the latest designed motors, which have the characteristics of large overload capacity and high mechanical strength. They are especially suitable for thousands of drives.
Various types of metallurgical and lifting machinery or other similar equipment. The YZR series is a wound rotor motor, and the YZ series is a cage motor.
1.2. The motor can operate normally under the following environmental conditions:
(1) The cooling medium temperature does not exceed 60°
C (metallurgical motor) or 40. C (motor for lifting)
(2) The altitude does not exceed 1,000 meters.
(3) Frequent and significant mechanical vibration and impact.
1.3. The motor can work normally under the following load conditions
(1) Frequent starts and reversals
1.4. The rated frequency of the motor is 50 Hz and the rated voltage is 380 volts.
1.5. Connection method: The stator windings with power of 132 dry watts and small 132 dry watts use Y connection method, and the rest use Y connection method.
