Embodiment Construction

[0014] The invention proposes a transverse magnetic field permanent magnet synchronous motor with a rotor magnetic pole three-wall structure, which is proposed to solve the complicated stator structure in the existing magnetic concentration type transverse magnetic field permanent magnet motor. The present invention will be described below in conjunction with the accompanying drawings.

[0015] figure 1 Including U-shaped stator core 5, annular stator winding 7, three-wall rotor permanent magnet poles 6, 10, 11; rotor cores 3, 4, 12, rotor bracket 2, rotating shaft 9, bearing 1. The stator 5 is made of U-shaped silicon steel sheets, forming a U-shaped iron core with the same number of pole pairs as the motor, which is evenly distributed along the circumference and fixed on the casing 8; the stator winding 7 is a ring coil structure, placed in the stator U-shaped The bottom of the core slot (such as image 3 shown); each phase of the rotor has two magnetic pole rings, and the...

Abstract

The disclosed horizontal magnetic-field permanent magnet synchronous motor comprises: the U-shaped stator with number same as motor pole pair fixed on shell, a ring stator coiling on bottom of U-shaped slot, every phase of rotor with two magnetic pole rings included 180deg electric angle to form main magnetic pole. This invention applies three-wall gather-magnetic structure for rotor to reduce iron core loss and increase magnetic air gap density.

Description

technical field [0001] The invention belongs to the field of permanent magnet motors, in particular to a transverse magnetic field permanent magnet synchronous motor with a rotor magnetic pole three-wall structure. Background technique [0002] Existing transverse magnetic field permanent magnet motors are mainly divided into two types: planar type and magnetism-concentrating type. The flat type has a simple structure, but has a low air-gap magnetic density and poor performance. The magnetic-concentration structure has a higher air-gap magnetic density and better performance, but the stator structure generally adopts an inner and outer double stator structure, or a three-dimensional stator core structure, which is more complicated and increases the difficulty and cost of manufacturing. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the stator structure is relatively complicated in the existing magnetism-concentrating ty...
