The invention discloses an E-shaped stator core flux switching type hybrid permanent magnet memory motor and belongs to the field of flux-adjustable permanent magnet motors. Both rotor and stator cores of the motor adopt a salient pole structure. A stator of the motor comprises six E-shaped stator cores, V-shaped aluminum-nickel-cobalt permanent magnets, tangential-magnetizing rectangular neodymium iron boron permanent magnets and a whole layer of stator yokes, wherein adjacent neodymium iron boron permanent magnets with opposite polarities are inlaid between the two adjacent E-shaped stator cores, and a three-phase concentrated winding armature winding is wound across a sandwich-shaped unit composed of the core edges of adjacent E-shaped stator units and the neodymium iron boron permanent magnets; a groove between two adjacent V-shaped aluminum-nickel-cobalt permanent magnets is used for placing a concentrated single-phase pulse winding. The E-shaped stator core flux switching type hybrid permanent magnet memory motor greatly alleviates a space conflict between electromagnetic loading in the stator cores and pulse magnet-adjustment capacity, can realize flexible online magnet adjustment and has little loss of excitation, the torque density and the force and energy expression of the motor can be improved, and the fault-tolerant fault operation ability is good.
Description
Technical field [0001] The invention relates to an E-shaped stator core magnetic flux switching type hybrid permanent magnet memory motor, belonging to the field of adjustable magnetic flux permanent magnet motors. Background technique [0002] In the field of motors, ordinary permanent magnet synchronous motors (PMSM) due to the inherent characteristics of ordinary permanent magnet materials (such as neodymium iron boron), the air gap magnetic field in the motor remains basically constant, and the speed regulation range is very limited during electric operation. Electric vehicles, aerospace and other wide-speed direct-drive applications are subject to certain restrictions. Therefore, the adjustable flux permanent magnet motor, which aims at realizing the effective adjustment of the air gap magnetic field of the permanent magnet motor, has always been a hot and difficult point in the field of motor research. . Permanent magnet memory motor (hereinafter referred to as "memory mot...
