RELUCTANCE MOTOR

摘要

A reluctance motor has: a stator provided with drive coils to which multiphase drive currents are inputted; and a rotor provided with a plurality of salient poles which receive primary rotating force when magnetic fluxes generated in the drive coils are interlinked with the rotor, and the rotor has: inductor pole coils which are placed on magnetic paths on which spatial harmonic components superimposed on the magnetic fluxes generated in the drive coils are interlinked with the rotor side so that induced currents can be generated in the inductor pole coils due to the spatial harmonic components of the magnetic fluxes; rectifier elements which rectify the induced currents generated in the inductor pole coils; and electromagnet coils as defined herein, and the inductor pole coils and the electromagnet coils do not serve for each other's purposes but are placed on the rotor individually.

1. A reluctance motor comprising: a stator provided with drive coils to which multiphase drive currents are inputted; and a rotor provided with a plurality of salient poles which receive primary rotating force when magnetic fluxes generated in the drive coils are interlinked with the rotor, wherein:
the rotor comprises: inductor pole coils which are placed on magnetic paths on which spatial harmonic components superimposed on the magnetic fluxes generated in the drive coils are interlinked with the rotor side so that induced currents can be generated in the inductor pole coils due to the spatial harmonic components of the magnetic fluxes; rectifier elements which rectify the induced currents generated in the inductor pole coils; and electromagnet coils to which the induced currents rectified by the rectifier elements are conducted as field currents so that the electromagnet coils can be self-excited to thereby generate electromagnetic force as auxiliary rotating force for assisting the primary rotating force, and the inductor pole coils and the electromagnet coils do not serve for each other's purposes but are placed on the rotor individually.
