[Abstract]:In this paper, the working principle and design method of permanent magnet DC motor are analyzed and studied, and a 2-pole 8-slot permanent magnet DC motor is designed. Using Visual basic language, a finite element analysis program of electromagnetic field of motor is developed. The finite element analysis program is used to calculate and analyze the performance of the designed permanent magnet DC motor. If the performance is not up to requirements, some dimensions of the motor are adjusted and calculated repeatedly. First, according to the design principle and experience of permanent magnet DC motor, the equivalent magnetic circuit method is adopted. Then, the finite element mathematical model of permanent magnet DC motor is established, and the two-dimensional finite element calculation program of electromagnetic field is compiled by Visual basic language, and the program is debugged by microcomputer. Using the finite element calculation program, the performance of the initial scheme is calculated, and the individual dimensions are adjusted according to the design requirements. After repeated adjustment and calculation, the final design scheme is determined. Finally, the running characteristics of the motor are calculated by using finite element calculation program for the final design scheme. The magnetic field distribution diagram and air-gap magnetic density curve, the electromagnetic torque curve and the working characteristic curve of the motor under no load and load, respectively, are plotted. The results are in good agreement with the experimental data. In addition, this paper introduces the features, functions and usage of the software. The design steps, design flow and running interface of the software are introduced in detail.
