Abstract: Being driven by natural commutating inverter, induction motor frequently self-excites due to peculiar circuit formation of inverter. Then in this paper we proposed the checking method of self-excitation of induction motor by controlling the DC excitation of inverter transformer, and proved its availability. It is shown in chapter 3 that self-excitation of induction motor is expressed as functions of circuit constants of inverter and degree of DC excitation of inverter transformer. From these facts we set up the relation between the bounds of induction motor and DC excitation of inverter transformer, and proved that self-excitation of induction motor could be checked by controlling the DC excitation of inverter transformer. In chapter 4, we calculated this theoretical results using the constants of 6KW inverter, compered this calculated values with experimental ones, and verified the theoretical results. Control method discussed here has special merits that self-excitation of induction motor is checked perfectly without changing the circuit constants of inverter and also its control procedure is very easy.
