Abstract

The paper describes a numerical method of calculating the magnetic fields, forces, inductances, and the dynamic behaviour of electromagnetic actuators. The solution of the non-linear partial differential equation for the magnetic vector potential is obtained by finite difference techniques using line iteration and acceleration of convergence. Examples of application are given for an electromagnetic print needle actuator.
