ELECTROPERMANENT MAGNET-BASED MOTORS |
摘要 |
An electropermanent magnet-based motor includes a stator having at least one electropermanent magnet, at least one coil around the electropermanent magnet configured to pass current pulses that affect the magnetization of the magnet, and a rotor that is movable with respect to the stator in response to changes in the magnetization of the electropermanent magnet. A wobble motor has a stator with a centrally-located core from which arms radiate outward, an electropermanent magnet and coil on each arm, and a rotor exterior to the stator such that the rotor can rotate around the stator arms. A rotary motor has a centrally-located rotor that rotates about its axis and a stator exterior to the rotor such that the rotor may rotate within the stator arms, the stator including an anteriorly-located stator core from which stator arms radiate inward toward the rotor, and an electropermanent magnet and coil on each stator arm. |
