Axial switch reluctance motor

Abstract

The present invention belongs to an electric transmission device filed, which is suitable for the transmission controlling in the special environment such as the electromotive vehicle filed, the food processing, the underwater operation, the nucleus industry, and the aviation field, The present invention consists of a rotor, a winding, a stator and an axis, the rotator and the stator are distributed along the axial direction. The directions of the rotator pole and the stator pole are along the axial direction, and the rotator pole and the stator pole are faced with each other along the axial direction. The pole number of the rotator and the stator can adopt the 6 to 4, 8 to 6, 12 to 8, or 4 to 6, 6 to 8, 8 to 12 and other type of the prior SRM proposal. The rotator and the stator adopt the different rotating axis, the rotator and the rotating axis can be completely separated from the stator. Due to the stator and the rotor has the distance along the axial direction, change the radial position to the axial direction relation, the radial size is decreased, the radial of the rotator is not limited, only need to form the magnetic loop with the stator at the axial direction, the energy transmission manner is changed to the direct axial direction transmission, and beneficial to the heating output of the electromotor, and suitable for using as the electromotor of the electric vehicle wheel.

Description

technical field [0001] The invention belongs to the field of electric transmission (mechanical transmission) equipment, in particular to an axial switched reluctance motor, which is suitable for transmission in the field of electric vehicles and in special environments such as food processing, wind power generation, underwater operations, nuclear industry, and aviation fields. field of control technology. Background technique [0002] In the 1980s, when the AC speed control system developed rapidly, a switched reluctance motor (SRM for short) appeared with simple structure, firmness, reliable operation, low cost, high efficiency, and good lateral torque and lateral power speed regulation performance. The speed control system composed of it has the advantages of both DC drive and ordinary AC drive. The structure of SRM's rotor without winding and stator concentric winding and its operating principle determine that it can achieve ultra-high-speed, low-loss operation and self-r...

Problems solved by technology

Therefore, it is of great significance to consider changing the traditional motor transmission mode, especially the energy transmission in the axial direction, such as the disc motor with the application number 85203304 and the axial air gap motor with the application number 87217225, and the axial air gap with the application number 87217225 The motor overcomes the disadvantage of excessive magnetic pull on one side of the disc motor with application number 85203304. Two stators are used on both sides of the rotor and arranged symmetrically to balance the magnetic pull on both sides. However, the rotor passes through the two stators. Forms a flux loop, greatly reducing the effective rotating flux

[0004] At present, there is no mention of axial switched reluctance motors in domestic and foreign literature and patent materials.
