Abstract:
1. A brushless multi-stage direct current electric motor, comprising: a. A plurality of inner rotors and two end rotors embedded with a plurality of magnets with the north pole facing the south pole forming one continuous loop of magnetic flux that flows in at least six paths; with three flux paths flowing in one direction and three flux paths flowing in the opposite direction in an axial fashion from end rotor to end rotor that is parallel with the motor shaft and across all the stators of the motor at the same time; b. said end rotors have a plurality of magnetic transfer plates affixed to the outer-most side of each end rotor to accept and redirect the loops of magnetic flux that flows across the stators; wherein c. the rotors are attached to a shaft to provide rotational torque, further comprising; d. A plurality of stationary non metal stators, machined for windings, is sandwiched between the rotors, the non metal stators, allows the axial flux to travel from rotor to rotor with no eddy currents, no cogging, and no head loss; and e. The plurality of windings is for receiving electrical power to produce a magnetic field around the wire windings; f. The windings are electrically powered with three phase direct current to produce a magnetic field about the windings, and g. A plurality of magnetic sensors that can be operated as a group of three sensors or as a group of six sensors for monitoring shaft position and timing of activation and deactivation of electrical power to the windings.
