<p>A bidirectional, axial air gap, brushless, printed circuit DC motor having a stationary, low inductance armature bonded to the motor frame and having a plurality of rotating permanent magnets. Electro-optical sensing is employed which produces a unique digital representation of the magnet position. The digital output of the electro-optical sensor is decoded and, using brush substitution techniques, is used to selectively and progressively energize fields in the armature winding ahead of the rotating magnets. Both single field per pole and multiple field per pole commutation techniques are taught. The armature may be cut so as to produce several independent coils which may be combined in various ways, depending on the application.</p> |
