摘要： A linear switched reluctance motor comprises a movable coil bracket including first and second coil assemblies. Each of the first and second coil assemblies further comprises a plurality of coils separately wound around a plurality of motor coil cores, each of the coils being configured to receive a sinusoidal current at a different phase from other coils comprised in the same coil assembly. Tooth members of a stator track are located adjacent to the motor coil cores such that a magnetic flux path is created which passes through the motor coil core, the stator track and an air gap between the motor coil core and the stator track. A multiple-phase motor driver electrically connected to the first and second coil assemblies generates symmetric multiple-phase sinusoidal currents for driving the motor.
