Abstract

In order to achieve the purpose, the invention provides a parametric design method of a multi-phase permanent magnet motor. The method is characterized by comprising the following steps of 1, inputting or modifying design variables of the motor; 2, inputting or modifying virtual testing configuration of the motor; 3, according to the design variables in the step 1, generating a motor design list needing to the estimated; 4, performing finite element modeling and setting on the motor in the motor design list in the step 3; 5, performing finite element virtual testing by means of the finite element model in the step 4 according to the parameters in the step 2; 6, performing post-processing on the result in the step 5; 7, repeatedly executing the steps 4-6 till all the parameters in the motor design list in the step 3 are estimated; 8, generating a motor design and performance report forms. The design method is applicable to radial flux permanent magnet motor design of any phase number, any pole-slot cooperation, various stator slot types and magnetic pole types.

Description

technical field [0001] The invention belongs to the technical field of motor design, and in particular relates to a parameterized electromagnetic design method of a multiphase permanent magnet motor. Background technique [0002] The permanent magnet motor uses rare earth permanent magnet materials with high magnetic energy product to replace the excitation winding, and has the advantages of high power density, simple mechanical structure, and high efficiency in the full speed range. It has been widely used in wind power generation, electric (hybrid) vehicles and ship propulsion and other fields. In addition, the output torque of the specially optimized permanent magnet motor is very smooth and stable, and the harmonic component of the air gap electromagnetic force is small, so it has the characteristics of low vibration and noise, and is especially suitable for high-end applications such as naval propulsion, aerospace and advanced manufacturing. occasion.
