Abstract

The invention discloses a three-freedom-degree magnetic levitation switch reluctance motor of a 12 / 4 pole structure. One three-phase 12 / 4 pole radial magnetic field bearing-free switch reluctance motor and two three-phase 12 / 4 pole axial magnetic field bearing-free switch reluctance motors are integrated. The three-freedom-degree magnetic levitation switch reluctance motor of the 12 / 4 pole structure comprises a radial magnetic field motor stator core (1), a radial magnetic field motor rotor core (2), an axial magnetic field motor rotor core (3), a radial magnetic field motor winding (4), an axial magnetic field stator core (5) and an axial magnetic field motor winding (6). The functions of a bearing-free motor and the functions of an axial magnetic levitation bearing are integrated, integration is high, radial suspension force, axial suspension force and torque are completely decoupled on the structure, the control method is simple, the suspension performance is good, the torque pulsation is small, the power density is high, and the high-speed adaptability is strong.

Description

technical field [0001] The invention relates to a three-degree-of-freedom magnetic levitation switched reluctance motor with a 12 / 4 pole structure, belonging to the field of bearingless switched reluctance motors and magnetic levitation bearings. Background technique [0002] The bearingless switched reluctance motor is a new type of magnetic levitation motor developed at the end of the 20th century. According to the number of windings on the stator, there are single-winding bearingless switched reluctance motors and double-winding bearingless switched reluctance motors. The control strategies of the two are different, but the mechanism of the levitation force and torque generation is the same. They both control the winding current to form an asymmetrical magnetic flux, and then generate a radial direction and size controllable. Suspension force, so that the motor has the ability to rotate and self-suspend. Compared with the double-winding bearingless switched reluctance m...
