Abstract :
A new method for reduction of transient torques in a three phase induction motor, for starting from rest is described. In this method an initial DC current in the stator windings is necessary. The procedure to find the necessary amount of this current is explained. The method is also tested in a digital simulation and compared with one of the previously proposed methods
