Abstract:
1. A linear switched reluctance motor comprising: a movable coil bracket including first and second coil assemblies, each of the first and second coil assemblies further comprising a plurality of coils, each coil separately wound around a respective 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, the number of coils in the first coil assembly being equal to the number of coils in the second coil assembly, and each of the coils in the first coil assembly being electrically connected to a separate one of the coils in the second coil assembly; a stator track comprising tooth members which 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; and a multiple-phase motor driver electrically connected to the first and second coil assemblies that is operative to generate symmetric multiple-phase sinusoidal currents, wherein an electrical degree of separation between a first coil in the first coil assembly and a second coil in the second coil assembly that is electrically connected to the first coil is 180 electrical degrees or odd multiples of 180 electrical degrees and, wherein each motor coil core further comprises a plurality of tooth members facing the tooth members of the stator track.
