Summary: | 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.
La présente divulgation concerne un moteur à réluctance commutée comprenant des aimants permanents et, en particulier, un moteur à réluctance commutée comprenant une pluralité de modules d'aimant permanent, le moteur ayant un aimant permanent (stator-PM) et un enroulement de bobine qui sont agencés sur un stator, l'enroulement de bobine étant agencé en tant qu'enroulement de dent de remplacement, le flux magnétique de l'enroulement de bobine et le flux magnétique de l'aimant permanent étant dans des directions opposées, un guide de trajet magnétique de l'aimant permanent étant ajouté de telle sorte que, lorsqu'un courant ne circule pas dans l'enroulement de bobine, le flux magnétique de l'aimant permanent à travers une ouverture et un rotor circule à peine et est mis en circulation uniquement à l'intérieur du stator, ce qui permet de supprimer le couple de détente, et, lorsqu'un courant est appliqué à l'enroulement de bobine, le flux magnétique induit (pôle N) généré par le courant appliqué et le flux (pôle N) de l'aimant permanent sont poussés de force vers l'ouverture par l'action de répulsion des mêmes pôles de telle sorte que le flux magnétique généré par l'aimant permanent et le flux magnétique généré par l'enroulement sont ajoutés dans l'ouverture, ce qui permet d'augmenter la force électromagnétique, et ainsi, un couple électromagnétique est plus élevé et une efficacité est augmentée et, malgré l'aimant permanent, la tension induite ou le couple de détente est supprimé.
본 개시는 영구 자석이 포함된 스위치드 릴럭턴스 전동기에 관한 것으로서, 구체적으로 고정자에 영구자석[Stator-PM]과 코일 권선을 배치하고, 코일 권선은 대체치아 권선으로 배치하고, 코일 권선의 자속과 영구자석의 자속 방향은 서로 반대 방향으로 하고, 영구자석의 자기 경로 가이드를 추가하여 코일 권선에 전류가 흐르지 않을 때 공극과 회전자를 통한 영구자석의 자속이 거의 흐르지 않고 고정자 내부로만 순환되어 코깅 토크가 억제되며, 코일 권선에 전류를 인가 할 때 인가된 전류에 의해 생성되는 유도 자속(N극)과 영구자석의 자속(N극)은 같은 극 끼리의 척력 작용으로 강제로 공극으로 밀어 공극에서 영구자석에 의해 생성된 자속과 권선에 의해 생성된 자속이 더해져 전자기력이 증가되어 더 높은 전자기 토크 및 효율이 증가하고 영구자석이 있음에도 불구하고 유도전압 이나 코깅 토크(cogging torque)를 억제하는 복수의 영구자석 모듈을 포함하는 스위치드 릴럭턴스 전동기에 관한 것이다. |
