A study on the thrust force of solenoid considering hysteresis phenomenon

In this paper, a study on effective method of analysis for the thrust force of solenoid is conducted. First of all, the method of analysis applying 2D axis-symmetric model which is equivalent to 3D model is proposed. Various characteristics of solenoid can be examined in limited time because the time of analysis is reduced. The method of applying minor loop considering hysteresis phenomenon is also suggested. The method of analysis is similar to actual phenomenon than the method applying initial magnetization curve. The minor loop can be experimentally obtained by measuring and interpolating many points of each material. Finally, validity of method is verified by the decrease in error compared to measured result.
