Reduce the impact on equipment and save energy
- Apr 12, 2018 -

Crane motors and metallurgical inverter motors are squirrel cage rotor motors. It integrates the advantages of traditional hoisting metallurgical motors and the advantages of variable-frequency motors, so that the motor can not only meet the needs of frequency start, braking, overload, reverse, overspeed, shock and vibration working conditions, but also to meet the inverter control operation The need to achieve soft start, four-quadrant operation, etc., thereby reducing the impact on the equipment, and save energy.

The power level and mounting dimensions of the motor are in accordance with the International Electrotechnical Commission (IEC) standards, and the corresponding relationship is the same and interchangeable with the German DIN42681 and Japanese JEM1202 standards. Motor insulation class F and H two. Class F applies to general places where the ambient air temperature does not exceed 40°C; class H applies to metallurgical sites where the ambient temperature does not exceed 60°C. Both motors have the same parameters.

Rated motor voltage 380V, rated frequency 50Hz, reference work system S3-40%. The motor adopts forced-air cooling to make the motor have a good heat dissipation effect in a wide frequency range. The motor insulation class and protection class are the same as the YZ and YZR motors. The motor mounting dimensions are the same as those of the YZ and YZR motors, ensuring good interchangeability. The motor design adopts a new design that is elegant and elegant. The H160 and above motors have independent power supply cooling fans to meet the requirements of ventilation and heat dissipation during low frequency band operation.
