Control system for commutatorless motor

摘要: A control system for commutatorless motor comprising a synchronous having multi-phase armature winding and field winding, frequency converter supplying a-c current of variable frequencies to the position detector detecting signal based on rotational motor, voltage setting circuit producing constant exciting reference determining magnitude terminal first operational nominal induced electromotive force representing vector sum reaction drop basis proportional signal, second obtaining phase difference between obtained from circuit, means controlling, given according as by advanced in derived controlling adjusting firing signal.
