BIFILAR BRUSHLESS DC MOTOR Abstract A brushless D. C. motor is disclosed having two bifilar winding wire pairs with each bifilar pair forming alternate windings. Each winding is switched by a transistor which has a back poled diode connected in parallel therewith. The control circuit sequences energization of single windings with each winding energized being in a different bifilar pair than the next preceding energized winding whereby when a transistor is switched off the other winding of the bifilar pair and the associated back poled diode protect the transistor and provide an energy conserving/heat eliminating path for the induced current. Each winding is further formed of a pair of subwindings having an angle of separation therebetween approximately half the angular separation between adjacent windings. RO978-046
