Abstract

The invention discloses a duplex-winding bearing-free switched reluctance motor of a composite structure. The motor comprises a motor stator, a motor rotor and motor windings. The motor stator is composed of a reluctance motor stator, a magnetic separation disc stator and a magnetic bearing stator. The motor rotor is composed of a reluctance motor rotor, a magnetic separation disc rotor and a magnetic bearing rotor. The magnetic bearing stator is of a [-shaped structure, and the magnetic bearing rotor is of a cylindrical structure. The reluctance motor stator and the reluctance motor rotor are both of a salient pole structure. The motor windings comprise the torque winding and the suspension force winding. The torque winding is wound on one tooth of a [-shaped iron core of the reluctance motor stator, one tooth of a [-shaped iron core of the magnetic separation disc stator and one tooth of a [-shaped iron core of the magnetic bearing stator. The suspension force winding is wound on the other tooth of the [-shaped iron core of the magnetic bearing stator. According to the duplex-winding bearing-free switched reluctance motor of the composite structure, the reluctance motor rotor generates torque, suspension force rotors generate suspension force, and decoupling of the torque and the suspension force is achieved structurally; motional electromotive force is zero in a suspension breakover interval, influences of the motional electromotive force on current chopped waves are eliminated, and the current real-time control effect is improved.

Description

technical field [0001] The invention belongs to the technical field of motors, and relates to a double-winding bearingless switched reluctance motor with a composite structure. 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 wound on the stator, it can be divided into single winding and double winding structures. Composite structure double-winding bearingless switched reluctance motor is to stack the levitation winding which generates the levitation force and the winding of the original switched reluctance motor on the stator of the motor. By controlling the current of the two sets of windings, it has the ability to rotate and self-levitate at the same time. , so as to realize the ultra-high-speed operation of the motor. [0003] There is a strong coupling relationship between the torque and the levitation force of the composite s...
