Printed circuit board disk type motor without iron core

Abstract

The invention discloses a printed circuit board disk type motor without an iron core. The printed circuit board disk type motor without the iron core comprises a motor shaft and two rotor disks, a stator disk is arranged between the two rotor disks, permanent magnets are simultaneously installed on the two rotor disks, air gaps are formed between magnetic steel surfaces of the two rotor disks and two end faces of the stator disk respectively, the stator disk is formed by superposing at least two layers of printed circuit axial boards, a plurality of radialized straight guide wires are uniformly spread on the circumferential surface of each layer of printed circuit board, two ends of a part of straight guide wires are sequentially in a series connection through arc-shaped guide wires spread on the printed circuit boards, and thereby a phase of winding in a multi-phase motor is formed. By means of the structure, the printed circuit board disk type motor without the iron core has the advantages of being light, small in size, good in power density and control performance, low in manufacturing costs, convenient to process and suitable for batch production.

Description

[0001] technical field [0002] The invention relates to a disk motor, in particular to a printed circuit board ironless disk motor. Background technique [0003] Axial flux permanent disk motors have the advantages of small size and high power density, and are widely used, especially the disk permanent magnet motors with two permanent magnet rotors and an axial magnetic circuit with a stator structure have simple structure, high efficiency, and in order to further improve the efficiency of the motor, the stator can adopt a coreless structure, that is, the stator coil is cast from polymer materials, but the existing motor structure, the casting process of the stator coil is relatively complicated, and the production and production The efficiency is low, and the consistency of the product is also very poor. Since the quality of the casting process directly determines the performance of the motor, the performance of this motor is poor and cannot meet people's needs for goo...
