Title:
THREE-PHASE AND FOUR-DEGREE-OF-FREEDOM AXIAL PHASE SPLITTING BEARINGLESS FLYWHEEL MOTOR
Document Type and Number:
WIPO Patent Application WO/2019/205683
Kind Code:
A1
Abstract:
The present invention relates to a three-phase and four-degree-of-freedom axial phase splitting bearingless flywheel motor, comprising a stator, a stator sleeve, a rotor, a rotor sleeve, and a flywheel. The stator and the rotor are divided into three parts in an axial direction, i.e., phase A, phase B, and phase C. An axial magnetizing permanent magnet is mounted between two adjacent phases. Twelve rotor poles and provided at equal intervals on inner sides of phase A, phase B, and phase C rotor iron cores, separately. Phase A rotor pole, phase B rotor pole, and phase C rotor pole are staggered at one-third rotor pole distance in sequence in a peripheral direction. Automatic start is carried out by enabling or disabling angle setting. Phase A and phase C stator iron cores are provided with eight narrow cogging torque poles and four wide cogging suspension poles, respectively. Phase B stator is provided with twelve equal-width torque poles. Control coils are wound on the torque poles and the suspension poles, separately. According to the present invention, automatic start and four-degree-of-freedom suspension are achieved, and effects of decreasing the torque pulsation and improving the torque output are achieved.
