Disc type permanent magnet motor comprising winding in printed circuit board structure

Abstract

The invention provides a novel disc type permanent magnet motor against the defects in the existing production and manufacturing process of an armature of the disc type permanent magnet motor, which is characterized in that a stator component is in a slotless structure or a coreless structure; an armature winding for generating electrical excitation is fixed on a stator, and a stator winding is in a printed circuit board structure; a magnetic pole of a rotor is made of permanent magnet material; and the motor does not comprise an electric brush and a commutator. By adopting the technical scheme, not only the production and manufacturing process of an iron core can be simplified, but also the processes, such as winding, paying off, wire connecting and the like can be simultaneously saved, thereby simplifying the manufacturing process of the armature of the disc type permanent magnet motor, which is complex originally, and bringing convenience to automatic mass production by using a machine. The disc type permanent magnet motor has the advantages of being convenient to mount, saving working time, being high in production efficiency, being firm in structure, being low in failure rate, reducing product defects caused by human factors, being applicable to mass production and being low in cost.

Description

technical field [0001] The invention relates to a disc permanent magnet motor, in particular to a disc permanent magnet motor whose winding is a printed circuit board structure. Background technique [0002] Disc permanent magnet motor is also called axial magnetic field motor because its air gap magnetic field is distributed along the axial direction. This kind of motor has a flat structure, short axial dimension, small moment of inertia, and high torque density. It is suitable for thin installation space drive or servo field. [0003] At present, the manufacturing process of the armature of the disc permanent magnet motor is a bottleneck restricting the wider application of the disc permanent magnet motor, which is mainly manifested in two aspects of the core production process and the winding process. In terms of core production process, the core of the traditional radial field motor is different from the stacked structure of silicon steel sheets. The core of the disc pe...

AI Technical Summary

Problems solved by technology

In terms of core production process, the core of the traditional radial field motor is different from the stacked structure of silicon steel sheets. The core of the disc permanent magnet motor is a winding structure of silicon steel sheets, and slots are made on the core of the winding structure. The process is quite complicated and the cost is high

In terms of winding process, the winding and off-line process of traditional radial field motors is mature, and most of them can realize automatic winding and off-line of machines, while the off-line process of disc permanent magnet motor is complicated, and the winding ends are seriously crossed and piled up. Unable to use the machine to automatically go offline, prone to man-made process defects, time-consuming and labor-intensive, and high production costs
