A Modular Switching Flux Disc Motor and System

Abstract

The invention discloses a modular switch flux disk motor and system, comprising: a stator, a rotor and two sets of windings; the stator includes two stator disks, the stator disk includes k stator modules, each of the stator modules includes m stator units and m connection blocks, the connection blocks are arranged between any two of the stator units, and the stator units and the connection blocks are arranged along the circumferential direction of the disc; the stator units include two first lamination segments , a second lamination section and two permanent magnets, the second lamination section is arranged between two first lamination sections; the permanent magnet is arranged between the first lamination section and the second between stacked segments. In the present invention, each stator plate is divided into k stator modules, each stator module includes m stator units, and each stator unit is composed of two first lamination sections and one second lamination section, thus The magnetic circuit coupling between windings of each phase is reduced, and the fault tolerance and utilization efficiency of permanent magnets are improved.

Description

Technical field [0001] The present invention relates to the field of motor technology, in particular to a switched magnetic flux disk motor structure with high torque density and compact space. Background technique [0002] In recent years, the disc permanent magnet motor has attracted more and more attention from researchers due to its compact structure, high efficiency, and high power density. There have been a large number of documents on the application of axial permanent magnet motors with various structures in different fields. Conducted in-depth research. Due to the advantages of high torque density and high power density, the switched flux motor is combined with the disc motor to form a switched flux disc motor, which is 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 wid...

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
