摘要： An electric motor includes a rotor and a stator including a stator core, a plurality of armature windings, a plurality of field windings, and a plurality of bonded magnets. The stator core has a plurality of teeth alternately defining field slots and armature slots along a circumferential direction, and a stator yoke magnetically coupling the plurality of teeth opposite the rotor. Each armature winding is wound around two of the teeth sandwiched between an adjacent pair of the armature slots. Each field winding is wound around two of the teeth sandwiched between an adjacent pair of the field slots. The magnets are individually located in the field slots while opposing the field windings in the radial direction. Each adjacent pair of the magnets along the circumferential direction respectively has an adjacent pair of pole surfaces, with the adjacent pair of pole surfaces having a same polarity.

摘要： An electropermanent linear actuator has a stator, forcer, drive circuitry, and feedback control mechanism. The stator includes at least one electropermanent magnet with a coil that passes current pulses that change the magnetization of the magnet, which change persists after current is removed. The forcer moves with respect to the stator in response to the persistent changes in magnetization. Drive circuitry controls the position or speed of the actuator by controlling the timing, magnitude, and/or shape of the current pulses. The voltage and duration of pulses are of sufficient magnitude to cause the magnetization change to persist after cessation of current, with voltage and current returning substantially to zero between pulses. The feedback control mechanism determines, based on actuator velocity or position, when the next current pulse should be issued, pulse issuance being timed so that the actuator will continue to move throughout the absence of applied current between pulses.

摘要： An electromagnetic actuator (100) comprises magnets (109, 111, 113, 115, 11), and a ferromagnetic structure (103) accommodating control conductors (118, 121, 123, 125). The magnets and the structure can move with respect to one another under control of control currents in the control conductors. The magnetic field in a gap (107) between the magnets and the ferromagnetic structure is oriented perpendicular to the direction of relative movement. The structure (103) accommodates damping conductors (127) that form closed loops of an electrically conductive material, different from the ferromagnetic material. The damping conductors (127) provide a damping force induced by the relative movement.
