ABSTRACT:
The invention discloses a controller for controlling an electric motor having a stator and an armature, the stator includes stator magnetic poles, the armature includes multiple two-node, open circuit armature windings. The armature windings are inductively linked the armature and insulated from the armature and from each other. The motor has at least one repeatable section, each repeatable section includes a group of poles and windings. The stator has two stator magnetic poles per repeatable section. The controller comprises magnetomotive force means for energizing the stator magnetic poles as a north pole and a south pole per repeatable section with adjacent poles being of opposite polarity, means to control electrical currents in from none to at least one two-node, open circuit armature winding thereby forming armature electromagnetic poles of various numbers to the strength levels available, with adjacent armature electromagnetic poles having opposite polarity, and with no more than two armature electromagnetic poles per repeatable section, to control the force and torque generated by the motor.
