YD series variable speed induction motor is one of the main series products deriving from three-phase series. This multi speed induction motor can change rotational speed to meet the requirements of load state, so that they can properly match the demands of power and simplify adjustments speed system. They are widely used in such industrial and agricultural departments, as machine tools, mining metallurgy, spinning and weaving, printing and dyeing, chemical industry and agricultural machine. YD multi speed induction motor is equivalent to other foreign advanced machines, and therefore they are matching with single-machine or machine for export as well as motors for similar types imported from abroad.

How to deal with the problem of high temperature of the motor body?
Content introduction: Motor technicians must investigate the causes of the above-mentioned faults one by one during maintenance. For example, if it is a voltage problem, use a voltage power supply that matches the rated voltage of the motor. If it is a motor load, it is necessary to determine whether the load is due to the insufficient power of the motor or the mechanical load driven by it is not working properly.
Motor repair is a relatively complex task. There are many possible reasons for the same failure problem. This requires us to investigate, and we must continue to summarize experience and summarize in the daily motor repair work. To
When the motor technicians face the problem of excessively high temperature of the motor body, the maintenance worker must carefully analyze it. First find out the cause of this problem, and then prescribe the right medicine.
There are several reasons why the temperature of the motor body is too high: one is the problem of the power supply, such as the voltage is too high, which far exceeds the rated voltage of the motor, or the voltage is too low, which causes the temperature of the stator and rotor windings to be high, and the other is the voltage. This situation will also occur if it is not symmetrical; the second is due to the load condition of the motor.
