Motor Cooling Fan Failure: Abnormal power supply.
The Fan Motor is a squirrel-cage three-phase asynchronous motor, and its performance is affected by power supply. When the power supply voltage fluctuates, over-voltage, under-voltage or three-phase voltage unbalance will affect the normal operation of the motor. In severe cases, it can cause damage to the motor.
Measures to be taken: in the circuit installation of over-voltage, under-voltage protection circuit. Motor cooling fan failure, the introduction of the small series to introduce everyone here, each motor before factory should do insulation resistance, voltage, no-load, short circuit, load test. Test data should be in line with national standards before they can be used outside the factory. If you want to know more about new energy vehicles, focus on electric.
