Title:
SWITCHED RELUCTANCE MOTOR COMPRISING PERMANENT MAGNETS
Document Type and Number:
WIPO Patent Application WO/2024/080774
Kind Code:
A1
Abstract:
The present disclosure relates to a switched reluctance motor comprising permanent magnets and, particularly, to a switched reluctance motor comprising a plurality of permanent magnet modules, the motor having a permanent magnet (stator-PM) and a coil winding that are arranged on a stator, wherein the coil winding is arranged as a replacement tooth winding, the magnetic flux of the coil winding and the magnetic flux of the permanent magnet are in opposite directions, a magnetic path guide of the permanent magnet is added so that, when a current does not flow into the coil winding, the magnetic flux of the permanent magnet through an aperture and a rotor hardly flows and is circulated only into the inside of the stator, thereby suppressing cogging torque, and, when a current is applied to the coil winding, the induced magnetic flux (N pole) generated by the applied current and the flux (N pole) of the permanent magnet are forcibly pushed to the aperture by the repulsive action of the same poles so that the magnetic flux generated by the permanent magnet and the magnetic flux generated by the winding are added in the aperture, thereby increasing electromagnetic force, and thus a higher electromagnetic torque and efficiency is increased and, despite the permanent magnet, induced voltage or cogging torque is suppressed.
