Permanent magnet motor uses permanent magnet to generate the magnetic field of the motor, without excitation coil excitation current, high efficiency simple structure, it is a good energy-saving motor, the application of permanent magnet motor has become more more extensive.


Today, permanent magnet motor manufacturers will introduce to you what design methods are usually used in the design to meet our needs produce a better motor.


1. Magnetic circuit method

The unevenly distributed alternating magnetic field in the permanent magnet motor can be equivalent to the corresponding magnetic circuit, so that the magnetic field calculation is transformed into the magnetic circuit calculation. Because many correction factors are used in the calculation of equivalent magnetic circuit, its value cannot be calculated theoretically. Empirical data are generally used.


2. Finite element method

In order to make the calculation accurate, it is necessary to analyze the electromagnetic field, such as the shape size of the permanent magnet magnetic stage, local demagnetization phenomenon. The numerical analysis of electromagnetic field by finite element software saves the development cost of products provides an accurate basis for the design of permanent magnet motor.


3. Field junction method

Although the calculation speed of magnetic circuit method is fast, but the degree is high, the computer calculation is high, but the calculation is slow the computer requirements are higher. Therefore, the combination of finite element method traditional magnetic circuit method in the numerical calculation of motor electromagnetic can only improve the calculation efficiency, but also improve the accuracy. This is of great practical value for motor parameter design.


The above is the motor design method introduced by the permanent magnet motor manufacturers. Nowadays, with the development of science technology, most permanent magnet motors can be applied without magnetic field control only armature control. Of course, there are many kinds of permanent magnet motors, different applications also need different motor equipment, so we should pay attention to it in the later use.
