More Information
Summary:In a brushless electric motor, a static commutator including thyristors, and an angular position detector for detecting the relative angular position between an armature winding and a d.c. excited rotor are provided. The thyristors are turned on in sequence with a predetermined commutation lead angle by the signals transmitted from the angular position detector. A compensating winding is also provided in addition to a field winding and is wound on the rotor. A d.c. excitation current proportional to the armature current flows through the compensating winding to compensate the magnetomotive force resulting from the armature reaction.
