Dynamic characteristics analysis of linear dc motor for the electric screen door

초록

In order to simulate the dynamic characteristics, we have developed a method of calculating the force of the linear dc motor screen door system which is using three-dimensional data of flux density in air gap from finite element analysis. We use the coil mesh data to calculate Lorentz forces of each coil. Then they are used for the dynamic characteristic analysis. The simulated dynamic characteristic is compared with experimental value.
