| Abstract: | Using symmetry,a theoretical analysis has been made on the Three-phase asynchronous motors running
with one phase cut off. By the change of electromagnetic moment and the current of the motor, the running criterion
of protection. with one phase cut down has been put forward, according to the relationship between the positive state
current and negative state current. |
