A Short Magnetic Circuit Switched Reluctance Motor Generating Axial Force

Abstract

The invention discloses a short magnetic circuit switch reluctance motor capable of generating axial force. A plurality of stator tooth electrodes are evenly distributed in the circumferential direction of the radial cross section on the inner wall of an motor outer shell. A sleeve is fixedly arranged on the outside of a rotating shaft in a sleeved mode, and a plurality of rotor tooth electrodes are evenly distributed in the circumferential direction of the radial cross section on the outer wall of the sleeve. The axial cross section of each stator tooth electrode is in a rectangle shape which is defined by four faces and is provided with an L-shaped notch, and each rotor tooth electrode is in an L shape defined by two vertical faces in the same axial cross section. Radial gas gaps are reserved between the radial ends of the rotor tooth electrodes and the radial ends of the stator tooth electrodes, axial gas gaps are reserved between the axial ends of the rotor tooth electrodes and the axial ends of the stator tooth electrodes, and the axial cross section shape of the stator tooth electrodes and the axial cross section shape of the rotor tooth electrodes define a complete rectangle shape with two gas gaps reserved. The structure of the stator tooth electrodes and the rotor tooth electrodes is changed to change magnetic circuits, circulating of the short magnetic circuits is achieved, and all kinds of performance of the motor is improved.
