  • ELECTRIC MOTOR
    Publication number: 20200313520
    Abstract: A low voltage high current 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) 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.
    Type: Application
