ELECTRIC MOTOR
First Claim
1. A permanent magnet DC electromagnetic heteropolar motor, including:
- (a) at least one permanent magnet rotor;
(b) a shaft in mechanical communication with the rotor such that axial rotation of the rotor causes axial rotation of the shaft;
(c) a stator including at least one stator winding; and
(d) a plurality of switches, each functioning to provide commutation switching for the stator so as to generate a torque on the rotor and thereby cause said axial rotation of the shaft,wherein the stator includes circumferentially distributed and radially directed slots therein that define corresponding radially directed elongate electrically conductive bars, wherein the bars extend radially from a common inner conducting ring, such that said at least one stator winding is formed by the bars.

Abstract
A low voltage high current permanent magnet DC electromagnetic heteropolar motor, including (a) at least one permanent magnet rotor; 48 (b) a shaft in mechanical communication with the rotor such that axial rotation of the rotor causes axial rotation of the shaft; (c) at least one stator winding; (d) a plurality of switches, each functioning to provide commutation switching for the stator so as to generate a torque on the rotor and thereby cause said axial rotation of the shaft, wherein a terminal voltage of said machine is equal to the voltage of one electrochemical cell, and wherein the power of said machine is at least 1 kW.
