Recently, permanent magnet motors have become widely known in the industry that among them hysteresis motor can be considered axial flux and radial flux. In fact hysteresis motors are a kind of synchronous motors that have unique capabilities. Simplicity of performance, good startup torque and constant speed at synchronous speed are a significant advantage of the hysteresis motor. With the advent of permanent magnet materials technology, the research, manufacturing and entry into the industry of hysteresis motors has sharply increased.
Electric motors are one of the most important and widely used components in different industries. Therefore, it is necessary to design and improve their performance.
In this thesis, the simulation of the hysteresis motors of axial flux and radial flux is performed with the objective function of the torque density using finite element method. In design and structures of the past, design and optimization for a particular model and a specific volume have been made and the design and comparison of all existing structures for a given volume has not been made, which is done in this thesis and the torque density has been calculated for all common structures in a given volume.
Consequently, due to the unique features and characteristics mentioned for the hysteresis engine, as well as the use of this type of engine for specific applications and using simulation results, and taking into account the constraints of construction and mechanical factors, ultimately the structure in a given volume with the maximum torque density is introduced.
