Abstract: High amplitude electromagnetic vibration machinery is vibration system running in electromechanical resonance and realizing high vibration displacement, electromagnetic analysis of high amplitude electromagnetic vibration machinery was basis of optimized design to the structural parameter of electromagnetic vibration machinery. For obtaining electromagnetic relationship, according to the magnetic circuit model of high amplitude electromagnetic vibration machinery, using the method of equivalent analysis of the magnetic circuit, relationship between the main magnetic flux and the winding current and that between the electromagnetic force and the current were deduced in great detail. Finally, the results obtained by using the method of equivalent analysis of the magnetic circuit are verified.
