Abstract

The invention provides a permanent magnet auxiliary synchronous reluctance motor and a mounting method thereof. The permanent magnet auxiliary synchronous reluctance motor comprises a stator and a rotor, wherein the stator comprises a stator iron core and a concentrated winding, and the stator iron core comprises a plurality of convex magnetic poles; the convex magnetic poles comprise magnetic pole teeth and tooth boots, and the widths of the tooth boots are larger than the widths Lc of the magnetic pole teeth; the rotor comprises a rotor iron core and a plurality of permanent magnet groups, and a plurality of permanent magnet slot groups are uniformly distributed on the rotor iron cores; each permanent magnet slot group comprises at least two layers of permanent magnet slots, and each permanent magnet group comprises a permanent magnet arranged in a corresponding permanent magnet slot; the permanent magnets in each permanent magnet slot group have the same polarity, and the polarities of two adjacent permanent magnet groups are opposite; and a relation between a minimum interlayer distance g between two adjacent layers of permanent magnets in each permanent magnet group and the widths T of the tooth boots is disclosed in the specification. According to the permanent magnet auxiliary synchronous reluctance motor, the reluctance torque is maximally utilized, so that the efficiency of the motor reaches a higher level.

Description

technical field [0001] The present invention relates to the field of motors, more specifically, to a permanent magnet assisted synchronous reluctance motor and an installation method thereof. Background technique [0002] The built-in permanent magnet synchronous motor is a motor that places a layer of permanent magnets inside the rotor and uses permanent magnet torque and reluctance torque. It mainly improves the performance of the motor by improving the performance of the permanent magnet. quasi-permanent magnets. However, rare earth is a non-renewable resource, and its price is expensive, so the wider application of this kind of motor is limited. [0003] In order to save rare metal resources and reduce the environmental burden, combining the advantages of synchronous reluctance motors and built-in permanent magnet synchronous motors, it is the general trend to develop permanent magnet assisted synchronous reluctance motors that use a small amount of rare earths or do no...
