The permanent magnet hysteresis motor has the advantages of both the hysteresis motor and the permanent magnet. This engine is ideal for applications for electric vehicles, compressor pumps, robots and precision industrial drives, such as inertial navigation systems and video recorders that require high-performance soft, low-performance, and high-performance audio. . In this article, we will model and simulate this engine. We first derive the dynamic equations of the engine by considering the Foucault effect, and then we present the equations of its state for simulation in the SIMULINK / MATLAB environment. Finally, we compare the results of the simulation with the results of the numerical method and the finite element. This comparison shows a good match for these results. The method presented in this paper is time-limited, faster than the finite element method, and has acceptable accuracy.

Today, the use of numerical methods in solving different problems is widely used. The application of these methods has been accompanied by the development and presentation of new and innovative methods in order to meet the different needs of numerical problems. Although numerical methods such as finite element are very time-consuming and costly in solving three-dimensional problems with multifaceted elements, the finite point method as one of the non-network methods has been able to attract many researchers with its unique capabilities. To provoke. In this paper, while introducing the finite point method, the numerical solution of numerical problems is explained using this method. In the following, this method is used as one of the fast and convenient methods in determining the distribution of stress under the feet. The results of the finite point method are analyzed using different shape and distribution functions of the points and compared with other common methods such as traditional and experimental methods as well as the finite element method. Comparison of results shows that the finite point method has a more acceptable speed and accuracy compared to other methods, especially the finite execution method.
