If the three-phase asynchronous motor used is a triangle connection, then after the lack of phase, there is a phase winding current will increase rapidly, resulting in burnout. If the star connection is used, the two-phase winding is burned when the phase is missing.

       When the motor is running, if the winding turns short circuit or insulation damage, it will also cause phase loss operation, resulting in a burning accident, but the probability of this happening is very small, for normal operationThree-phase asynchronous motorThe probability of such an accident reaching will be smaller.

       In general, the causes of motor coil burn out are mainly related to electrical failure, mechanical failure, environmental factors and other reasons:

       1Electrical failure: the supply voltage is lower than the rated voltage of the motor;Motor running without phase;Three-phase asynchronous motorOverload operation

       2Mechanical failure: rotor sweep,Constant rotor friction,Bearing poor lubrication,Brake failure,The motor is stuck;

       3Environmental factors: The ambient temperature is too high;The working environment is too dusty,Motor surface ash prevents heat dissipation coil quality problems, part of the coil damage, coil aging, insulation paint is less, insulation paint aging, etc., will cause short circuit, called inter-turn short circuit.
