Abstract: 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.
