Abstract :
In this paper, the weak harmonic voltage of SPWM frequency converter 3-phase cage induction motor variable-speed system which is single pole modulation model at carrier wave ratio N=9 and modulation degree M=0.99 employed to form completely new 3-phase cage induction motor variable current servo-system by way of amplitude control. It is our hope that the motor could be developed into existence soon and so that further tests on such system could be performed
