Structure Optimization Design and Analysis of Transverse Flux Linear Oscillation Motor with Moving Stator

The electromagnetic and vibration characteristics of transverse flux linear oscillatory motor with different magnetization methods are compared and analyzed. The spatial distribution of air gap magnetic field of linear oscillatory motor with two different magnetization methods is calculated by finite element method. Moreover, the electromagnetic harmonics are extracted and used to analyze the harmonic response of the motor working system. Through the method of multi physical field coupling calculation, the natural frequencies and harmonic responses of the two motors are compared and analyzed. It is concluded that the performance of Halbach linear oscillation motor is better than that of magnet concentrating linear oscillation motor in terms of electromagnetic performance and mechanical vibration performance, which lays a foundation for subsequent motor optimization design.
