Transverse flux permanent magnetic motor and method for manufacturing stator thereof

Abstract

Disclosed are a transverse flux permanent magnetic motor and a method for manufacturing a stator thereof. The motor is axially equipped with two or three phases of electromagnetic induction components, and each phase of electromagnetic induction component consists of a stator and a rotor. An iron core of the stator is assembled by a left portion, a middle portion and a right portion, and jointing surfaces of the three portions of the iron core of the stator are conical surfaces utilizing a motor shaft as a symmetrical shaft. The left portion and the right portion of the iron core of the stator are formed by overlapping a plurality of annular silicon steel plates with the same outer diameter and then processing further, the middles of the left portion and the right portion are respectively provided with a through hole with symmetrical tooth profile on the periphery, the outer appearances of the left portion and the right portion are respectively a conical surface which is inclined to the middle and gradually reduced in radius, the middle portion of the iron core of the stator is formed by utilizing a silicon steel plate with equivalent width to wind axially to form a thin-wall cylindrical structure and then processing the thin-wall cylindrical structure further, and two ends of a through hole of the middle portion are respectively equipped with an internal conical surface which is dovetailed with each outer diameter conical surface of the left portion and the right portion of the iron core of the stator. By aid of the stator structure, volume of the motor can be reduced, and power and torque density of the motor are increased.

Description

technical field [0001] The invention relates to a permanent magnet motor with a novel structure, in particular to a transverse flux permanent magnet motor and a manufacturing method for a stator thereof, and belongs to the technical field of permanent magnet motors. Background technique [0002] With the development of science and technology in the field of robotics and aerospace, people's requirements for high power density, high torque density or direct drive motors are becoming more and more urgent and intense. [0003] In the traditional motor structure, the teeth where the magnetic flux passes and the grooves where the armature windings are located are located in the same section, the plane where the magnetic force lines are located is parallel to the rotation direction of the motor, and the width of the grooves and the width of the teeth are mutually restricted. If a larger current needs to flow through, a larger coil cross-sectional space is required, and the width of...

Problems solved by technology

[0005] see figure 1 , introduce the stator structure of the transverse flux permanent magnet motor developed at home and abroad, which basically adopts the U-shaped iron core uniformly distributed in the circumferential direction, and there is a large gap between every two stator cores, so in a certain To a certain extent, the space between the U-shaped iron cores is wasted, and the volume of the motor is increased
