Abstract

The invention discloses a transversal magnetic flux variable-reluctance permanent magnet motor which relates to the field of a motor and solves the problems of complicated secondary structure and low reliability and current control accuracy. The secondary structure comprises a secondary iron core. The primary structure at least comprises a phase unit. Each phase unit consists of a phase unit iron core, a phase unit winding and a permanent magnet. The phase unit core consists of a plurality of iron core units and is provided with a sprocket hole. The sprocket hole is formed by stacking gear slots of the iron core units. A permanent magnet is arranged on the sprocket of each iron core units, and the magnetic field directions of the magnets on sprockets of adjacent iron core units are opposite to each other. A coil is wound into a one-phase phase unit winding through the gear hole of the phase unit core. The motor can be used as a motor and also can be used as a generator. The permanent magnet of the motor is arranged on the gear of the core unit, therefore the secondary structure has simple structure and high reliability. The vortex loss of the motor is reduced, the motor efficiency is enhanced, the control accuracy of the current is high, and the motor is easy to modularize.

Description

technical field [0001] The invention relates to motor technology, in particular to a transverse magnetic flux variable reluctance permanent magnet motor. Background technique [0002] The structure of the traditional flat-plate linear permanent magnet synchronous motor is as follows: Figure 28 shown. The motor has an integer slot structure, that is, the number of slots per pole and phase of the motor is an integer number. The main problems of the linear permanent magnet synchronous motor with an integer slot structure are: on the one hand, the positioning force of the motor caused by the cogging effect is large; The performance-to-volume ratio of the motor is low, which is mainly due to the p When the design is large, the magnetic yoke of the permanent magnet will be thickened, which will increase the volume and weight of the motor, and when the pole pitch τ of the motor is p If it is designed to be small, the tooth pitch of the armature core will be τ t is very small, w...
