The current variation of three phase asynchronous motor in the absence of phase
When the asynchronous motor runs normally, the three-phase AC current is equal and less than or equal to the rated value due to the symmetrical load of the three-phase motor. If a phase break occurs, the line current is zero, so that the other two phase current will increase. For example, the motor is triangular connection, when the U phase is disconnected, the U and W two phase windings are connected in series and then connected with the V phase winding and connected to the V and W two-phase power supply. At rated load constant phase current V phase winding maximum is 2 times of normal operation (which is 1.16 times the rated current of the motor), and phase current of U and W phases remains unchanged, and the line on the line current is increased to the rated current of the times. Because the phase current of the V phase winding is twice as large as the normal operation, the winding is overheated.
