Abstract

In recent years, the application of high speed motor in various fields has attracted extensive attention. Due to the high speed of high-speed motor, the iron consumption of its loss occupies a large proportion, how to reduce iron consumption and improve efficiency is the key to motor design. This paper presents a mathematical model for the design optimization of permanent magnet direct current motors. This model can be used to calculate armature reaction parameters, brush pressure drop characteristics and magnetic saturation parameters of the motor, in combination with electromagnetic and physical variables of the motor. This paper presents a variety of variable conversion methods, so that the model can be widely applied to various types of permanent magnet DC motor. After the model is embedded in the computer program, the program can determine the optimal design parameters of the motor system. In this paper, using orthogonal design method, the principle of mathematical statistics, through the establishment of a permanent magnet DC motor program design, orthogonal analysis program and a comprehensive design program, scientific analysis results, determine the factors affecting the size, in order to find an optimum design scheme.
