Structure and method of combined stator iron core claw pole transverse magnetic flux permanent magnet brushless motor

Abstract

The present disclosure proposes a combined stator iron core claw pole transverse magnetic flux permanent magnet brushless motor structure and method, including: a rotating shaft, a rotor and a stator sequentially arranged from the inside to the outside; It consists of phase stator modules. Each phase stator module includes a stator yoke, stator teeth and a phase winding coil. The stator teeth are composed of stator tooth tooth bodies and stator tooth tooth shoes. The stator tooth tooth body is partially embedded in the stator yoke. The stator tooth shoe and the stator tooth body have the advantages of high torque density, high efficiency, strong overload capacity, simple manufacturing process and simple driving control mode.

Description

technical field [0001] The present disclosure belongs to the technical field of electric motors, and in particular relates to a structure and a method of a combined stator iron core claw-pole transverse magnetic flux permanent magnet brushless motor. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] There is no very strict definition of direct drive motor at present. Its main feature is low speed and high torque. Generally, it refers to a motor whose speed is lower than 500 rpm and can directly drive the load. For a direct drive motor with a design speed below 50 rpm, it is called an ultra-low speed direct drive motor. At present, the direct drive motor has a very wide range of applications in the industrial field, and has gradually begun to play a role in commercial ventilation, industrial production transmission systems, oil field explor...

Problems solved by technology

[0012] 2. Application of new materials in claw pole transverse flux permanent magnet brushless motors

[0013] 3. Motor cogging torque optimization problem

[0014] 4. Motor manufacturing and processing technology issues

Because the structural shape of the claw pole transverse flux permanent magnet brushless motor is obviously different from the current various traditional motors, many empirical formulas and graph curves used for conventional motor design are not applicable to the claw pole transverse flux permanent magnet brushless motor. motor design

[0015] 5. The drive control problem of the direct drive motor. Because the direct drive motor directly drives the load, the intermediate reducer link is omitted, so higher positioning accuracy is required

In addition, the traditional servo motors commonly used at present, the magnetic circuits of each phase of the stator are coupled with each other, resulting in complex mathematical models for motor control and difficult solutions, which affect the accuracy and speed of motor drive control
