Abstract

The invention discloses a 12 / 14 bearing-less switched reluctance motor with an adjustable air gap. The 12 / 14 bearing-less switched reluctance motor comprises a rotor core and a stator core; the rotor core is connected with the stator core through a shaft (8); the rotor core comprises a rotor yoke (6) and rotor magnetic pole teeth (7), wherein the rotor yoke (6) is positioned in the bottom end; uniformly distributed 14 rotor magnetic pole teeth (7) are embedded at the upper end of the rotor yoke (6); the stator core comprises a stator yoke (1) in the topmost end, 4 stator auxiliary magnetic pole teeth (2) and 8 stator torque magnetic pole teeth (3); the stator auxiliary magnetic pole teeth (2) comprise adjusting magnetic pole teeth (11) and permanent magnets (10) tightly clung to the inner sides of the stator auxiliary magnetic pole teeth (2); and a gap exists between the stator core and the rotor core to form the air gap (9). The 12 / 14 bearing-less switched reluctance motor has the characteristics of the axial suspension, the adjustable air gap, and the high power density.

Description

technical field [0001] The invention relates to a bearingless switched reluctance motor, in particular to a bearingless switched reluctance motor with an adjustable air gap, which is especially suitable for applications with low speed, high torque and small axial space. Background technique [0002] The traditional switched reluctance motor rotor has no permanent magnets and no coils. It has a simple structure, durability, high reliability, and good controllability. Therefore, it has been greatly developed. The products are widely used in electric vehicle drive systems, household appliances, and general industries. However, with the increasingly prominent energy crisis and environmental problems, the problems of traditional switched reluctance motors such as large torque ripple, low energy conversion density, and high noise have also attracted widespread attention. Subsequently, the switched reluctance motor that generates a disk-type axial magnetic field not only combines t...
