An improved electric motor

摘要

A highly efficient electric motor for converting electrical energy into rotational mechanical energy having at least one bobbin (3) wound stator coil through which passes a ring rotor upon which a plurality of permanent magnets are mounted. The permanent magnets are circumferentially mounted around the axis of rotation of the ring rotor having their North poles alternatively facing toward and against the direction of rotation. The bobbin (3) wound stator coils receive electrical signals from an electronic controller, causing the coils to generate magnetic fields which attract and then repel the permanent magnets mounted on the ring rotor (1). This electric motor may be ganged together with one or more other motors of this design to increase the mechanical power output. This electric motor may also be driven by an external torque applied to the output shaft (8) of this motor whereby mechanical energy may be converted to electrical energy.
