Abstract: PURPOSE:To obtain a fine multi-step frequency generating function, by a method wherein a two-way control recitifying element is connected to each of the windings of a six-phase induction motor and each element is switch-controlled by a specified method. CONSTITUTION:Windings of three phases of a six-phase induction motor 3 which have successive 120 degree difference are connected to two-way control rectifying elements THU-THW and winding of other three phases opposite to the former three are connected to the elements THU1-THW1. Another end of each element is connected each other in a manner such as THU, THU1 and is connected to each phase of a three-phase source. Switching is made between the elements such as THU and THU1 at every period of no half-waves of the source. The switching is repeated K-1 times and at the K-th time the switching is made at the period of n0+ or -1 half-waves of the source and an output is generated so that the frequency of 1/(n0+ or -1/K) times of the source frequency is obtained. Thus the fine multi-step frequency generating function is obtained, so that the multi-step speed driving or the continuous variable speed driving at the speed less than a half of the synchronous speed can be made possible.
