摘要： A linear flux switching permanent magnet (FSPM) motor includes a longitudinal, linear stator with stator teeth facing an air gap and a mover including at least one armature including armature teeth embedding at least one permanent magnet, which armature teeth are spaced apart by slots for receiving an armature winding, and which armature teeth have an extended width portion towards the air gap. The extended width portion of the armature teeth begins in the longitudinal direction of the armature teeth already at the level of the armature windings.

摘要： A method for levitation control of a linear motor includes supplying an alternating current or alternating voltage to at least one oscillating circuit including at least one sensing coil being or assumed to be arranged in a fixed spatial correlation to a mover part of the linear motor such that an opening plane of the sensing coil faces a sensor counter-surface of a stator part of the linear motor with a gap therebetween; receiving a response signal from the oscillating circuit; determining a gap length of the gap based on the response signal; and controlling the gap length by driving a magnetic levitation unit of the linear motor based on the determined gap length. An inductive sensing device and an elevator system, and a method for determining a position of the linear motor are also disclosed.
