AC motor testing system based on energy self-feedback

In order to solve the problem of performances testing in AC motor design and manufacture, several motor control methods such as the frequency control and energy feedback were investigated. A new testing system called energy self-feedback AC motor testing system was proposed. The design principle and rationality of the system were analyzed, the feasible and stable were proved by simulations and experi- ments. At last, the development direction of the new system was pointed as well. The research results show that, the system has advantages in simple structure, easv control and little effect to grid when feeding hack.
