Electromagnetic Mechanism Design and Analysis of Electromagnetic Engine

摘要

In order to solve the design problem of the electromagnetic mechanism of the electromagnetic engine, a method for the design of electromagnetic mechanism is proposed by means of finite element method and magnetic circuit method. According to the structure characteristics of the electromagnetic mechanism, the relation expressions of magnetic conductivity, magnetic leakage, magnetic resistance, total flux, magnetic potential and other parameters are deduced, and the calculation model of electromagnetic coil and core size is determined. Using three dimensional finite element method, the analysis of the electromagnetic coil current, electromagnetic agencies within the armature contact with iron core in the separation and two kinds of state, the magnetic induction intensity, magnetic field intensity and distribution of electromagnetic energy. The simulation results show that the electromagnetic mechanism has high magnetic conductivity, and the magnetic field intensity and magnetic energy distribution are uniformity.
