Abstract

The invention consists in providing a new brushless dc motor of new and improved type, which can be manufactured economically; that can be built in an extremely small volume; or that may be provided with axis position detectors located inside the envelope of the extreme turns of the armature winding. Another object of the invention is to provide a new and improved circuit that responds to an internal voltage state of the armature windings to detect the position of the rotor axis and to accumulate signals indicative thereof, whereby switching can be effectively performed of the energization signals of the windings.
