Lifting motor and metallurgical frequency conversion motor for squirrel cage rotor motor. It combines the advantages of traditional lifting metallurgy motor and frequency conversion motor, so that the motor can not only meet the needs of frequency starting, braking, overload, reversal, overspeed, impact and vibration work occasions, but also meet the needs of operation under the control of frequency converter, realize soft start, four-quadrant operation, etc., thereby reducing the impact on equipment and saving energy.
Introduction
The rated voltage of the motor is 380V, the rated frequency is 50Hz, and the reference duty system is S3-40%. The motor adopts forced ventilation cooling mode, which makes the motor have good heat dissipation effect in a wide frequency range. The setting of insulation grade and protection grade of motor is the same as that of YZ and YZR motors. Motor installation size and YZ, YZR motor is the same, thus ensuring good interchangeability. The appearance of the motor adopts new design, beautiful and elegant. Motors above H160 are equipped with cooling fans with independent power supply to meet the requirements of ventilation and heat dissipation during low frequency operation. Basic series without encoder, overspeed switch, etc.(suitable for switch control), encoder, overspeed switch, brake, etc. can be installed according to user needs. It is the ideal power for metallurgy and lifting machinery. The products are widely used in metallurgy, lifting, water conservancy and electric power industries.
