Problems solved by technology

Fourth: Due to the double-convex structure of the switched reluctance motor and the switching power supply mode, since the stator and the rotor poles rotate in opposite directions, the reluctance value between the stator and the rotor poles changes periodically in a large range, so that the reluctance is periodic The change of the magnetic circuit causes the magnetic circuit to be partially saturated periodically, thus generating serious noise and mechanical vibration
Fifth: Since the stator adopts salient poles and concentrated excitation windings, when one concentrated winding is energized and transformed into another concentrated winding, the angle at which the stator magnetic pole moves one step is 45° electrical angle, and the motor has poor low-speed performance and a small speed regulation range Wait for the problem to arise

Abstract

Recessive movable structure is adopted in stator magnetic pole. Number of magnetic pole of stator is equal to number of magnetic pole of rotor. Each magnetic pole of stator generates electromagnet force to pull rotor rotation in same direction and same speed. DC power supply is adopted in the generator. Moving speed and direction of magnetic pole of stator is decided by energized rule of stator winding, and energized rule for stator winding is decided by control system. Advantages are: simple structure. High reliability, high efficiency and good performance of speed adjustment.

Description

technical field [0001] The invention relates to a mechanical device for converting electric energy into mechanical energy, which is a switched reluctance motor with the same number of invisible moving stator magnetic poles and stator rotor magnetic poles. Background technique [0002] Switched reluctance motor is a new type of speed-regulating motor. It has the characteristics of simple and firm structure, low manufacturing cost, and excellent speed-regulating performance. It is one of the hot spots of research and development in various countries. The switched reluctance motors currently applied and researched at home and abroad, such as four-phase 8 / 6 poles, five-phase 10 / 8 poles, 6-phase 12 / 10 poles and other reluctance motors, have double salient poles for their stator poles and rotor poles. The structure and stator excitation adopt centralized winding, the position of each stator pole is fixed, and the number of stator poles is not equal to the number of rotor poles. F...
