In industrial and agricultural production operationsThree-phase asynchronous motorHas been widely used, the fault is also different; Among them, the lack of phase operation is the common fault of the motor, below andMori machineLet's understand what causes the motor to run without phase, and what will happen to the motor at this time?

       Three-phase asynchronous motorPhase loss operation means that the three-phase power supply of the stator winding of the motor lacks a phase. When the motor is missing a phase, if the motor is energized at this time, the general electric will emit a "buzzing" sound, and the speed of the motor can be felt to be relatively slow. If the load of the motor is relatively heavy, it can not reach the specified speed when starting in this case, or even start up; If it stays that way for too long,Three-phase asynchronous motorIt will cause the motor to overheat because of a long time of high current, and in serious cases, it will smoke and fire or even burn.

       If the motor suddenly lacks a phase during operation, the speed of the motor decreases quickly, the current of the motor stator winding will increase a lot, and there is a "buzzing" sound, in this caseThree-phase asynchronous motorDo not run it for a long time, otherwise it will burn.

       Lack of phase operation is very harmful to the motor, but we can use some protective measuresThree-phase asynchronous motorTo protect; For example, the stator windings are joinedYWe can use a two-stage or three-stage structure of the thermal relay for phase protection; If the motor stator windings are connected△Then we can only use three-stage relay with phase break protection device to carry out phase break protection.
