What do we mean by the absence of phases all the time? How to understandThree-phase asynchronous motorMissing phase operation and missing phase start-up, what is the relationship between the two, and what are the hazards? todayMori machineXiaobian will talk with you about the topic of lack of phase.

       Asynchronous motorPhase loss operation simply means that there is a phase break in the three-phase power supply. Breaking a firewire or a phase winding will form a short-phase operation, commonly known as single-phase; If the load on the shaft does not change, the motor is in a serious overload state, the stator current will reach twice the rated value or even higher, and the motor will burn out for a little longer. In various industries, the proportion of motors burned due to phase-out operation is large.

       This is because the motor has been out of phase because it has its own starting torque, so it can run for a period of time, but the speed has a significant decline, if the load does not decline at this time, then the other two-phase stator current is too large, it is easy to burn the motor.

       After the motor stops due to the lack of phase operation, because the motor has no starting torque at this time, the motor that is stopped at this time can not be restarted. We know that this motor has a rotating magnetic field as a prerequisite for rotation, but the phase-out start cannot generate a rotating magnetic field, so it cannot start by itself.
