A dual-mode reluctance motor

Abstract

The invention provides a double-mode magnetic resistance motor, which comprises a stator iron core, an outer rotor iron core, an exciting winding, an armature winding, a stator isolation block and a shaft and belongs to the technical field of a special motor. 16 uniformly distributed rotor poles are arranged on the outer rotor iron core; the stator iron core consists of six fan-shaped iron cores; the fan-shaped edge of each fan-shaped iron core is provided with two armature stator poles; the pole arc mechanical angle of each armature stator pole is 9 degrees. The exciting winding in the double-mode magnetic resistance motor is not electrified; the motor realizes electric or power generation operation in a work mode of switching on or switching off the magnetic resistance motor; the exciting winding is electrified; the motor realizes the electric or power generation operation in a work mode of electrically exciting a double-convex-pole motor. Meanwhile, according to the technology, the stator isolation block does not conduct magnetism, so that the coupling between stator sub iron cores is small; in addition, the motor is an integrated winding permanent magnet motor, so that the magnetic path is short; the copper loss and iron loss consumption is low; the efficiency is high.

Description

technical field [0001] The invention relates to a dual-mode reluctance motor, which belongs to the technical field of special motors. Background technique [0002] Electrically excited doubly salient motors are similar to switched reluctance motors in structure, and they also have a lot in common in terms of torque characteristics. However, there are great differences between electrically excited doubly salient motors and switched reluctance motors in terms of working principle, motor performance, and control methods. Therefore, in order to better adapt to changes in working conditions, the working modes of the two motors can be concentrated on one motor, that is, the dual-mode reluctance motor referred to in this application. According to the change of the working environment, the two working modes can be switched to make the motor work in an efficient and reliable state all the time. [0003] Currently related patents mainly focus on switched reluctance or doubly salient...
