Permanent magnet motor supply: The motor refers to an electromagnetic device that converts transmits electrical energy according to the law of electromagnetic induction. In the process of use, the motor often occurs failure is tripping, tripping only affects the normal use of the motor, but also easy to burn out the motor, today Xiaobian will give you a summary of the cause of the motor can start tripping, I hope to help you.


1, the motor can start the cause treatment method


The fuse of a certain phase is broken, the phase is missing, there is a humming sound. If the two-phase fuse is broken, the motor does move is silent. Find out the cause of fuse failure to eliminate it, replace the fuse with a new one.


The supply voltage is too low, the voltage reduction is too much when the start is reduced. The former should find the reason; The latter should be appropriate to increase the starting voltage drop, such as the use of auto-reduced starter, can change the tap to increase the starting voltage.


2. Cause analysis of motor trip during operation


The motor its electrical circuit short-circuit fault, tripping by the action of the protective device, for example, the motor is short-circuited due to insulation damage, the winding is burned off due to overheating, the introduction of a large amount of external water is short-circuited grounded.


The mechanical failure of the motor is serious, the load increases sharply the oil overload over-current protection action trips. The motor itself protects false action tripping, such as wiring errors, relay failures, protection setting errors, DC system two-point grounding, etc., at this time, there is no impact on the electrical system.


Permanent magnet motor supply: The above is likely to cause the motor trip can start, if you also encounter similar problems may wish to try according to the above method!
