The modularized switch flux disc motor comprises a stator, a rotor and two sets of windings, wherein the stator comprises two stator disks; each stator disk comprises k stator modules; each stator module comprises m stator units and m connection blocks; the connection blocks are arranged between any two stator units; the stator units and the connection blocks are arranged along the circumferential directions of the disks; and each stator unit comprises two first laminated segments, a second laminated segment and two permanent magnets, the second laminated segment is arranged between two first laminated segments and the permanent magnets are arranged between the first laminated segments and the second laminated segment. According to the modularized switch flux disc motor, each stator disk is divided into k stator modules, each stator module comprises m stator units and each stator unit comprises two first laminated segments and one second laminated segment, so that magnetic circuit coupling of each phase of winding is reduced and the fault-tolerant ability and the utilization efficiency of the permanent magnets are improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a structure of a high torque density and compact space switched magnetic flux disc motor. Background technique [0002] In recent years, disk permanent magnet motors have attracted more and more attention from researchers due to their compact structure, high efficiency, and high power density. There have been a large number of literatures on the application of axial permanent magnet motors with various structures in different fields. conducted an in-depth study. Due to the advantages of high torque density and high power density, switched flux motors are combined with disc motors to form switched flux disc motors, which are especially suitable for occasions requiring high torque density and compact space, such as electric vehicles and renewable energy systems , flywheel energy storage system, etc. In order to overcome problems such as unilateral magnetic pull, the most widely st...

AI Technical Summary

Problems solved by technology

The traditional switched flux disc motor adopts U-shaped iron core lamination section, the output torque is limited, and the efficiency of the permanent magnet is low. The magnetic circuit between the windings is coupled to each other through the yoke of the iron core, and the magnetic field between the phases also interferes with each other. , leading to poor fault-tolerant performance of the motor
