The variable frequency variable speed motor for hoisting motor and metallurgy is wound motor rotor motor. It combines the advantages of traditional lifting metallurgy motor and frequency conversion motor, so that the motor can not only achieve the frequency start, brake system, load, reverse, overspeed, impact and vibration in the workplace must, but also achieve the frequency conversion governor under the control of the operation must, complete the soft start, four-quadrant operation, and so on, thereby reducing the impact on machinery and equipment, and save resources.
The rated current of the motor is 380V, the rated frequency is 50Hz, and the standard working hour system is S3-40%. The motor adopts forced air supply refrigeration method, which promotes the motor to have excellent heat removal effect in the wide working frequency range. The installation of flame retardant grade and waterproof grade of motor is the same as that of YZ and YZR motors. Motor installation specifications and YZ, YZR motor the same, thus ensuring a better tolerance. The appearance design of the motor adopts a new design scheme, which is unique. Refrigeration centrifugal fan with separate power supply system for motor above H160 to meet the requirements of natural ventilation and heat removal in low frequency operation. Basically, the series products have no servo motor, overspeed switch, etc.(suitable for switch operation), servo motor, overspeed switch, braking system, etc. can be modified according to user needs. It is the idealized driving force of metallurgy and lifting machinery and equipment. The products are widely used in metallurgy, lifting, water conservancy and hydropower fields.
