Abstract :
A transient 2-D finite element model for fast-acting pulse-width-modulated (PWM) solenoid actuators is presented. The unique feature of this model is that it couples the electrical, mechanical, and magnetic systems of these devices. Transient calculations taking into account the nonlinearity of the magnetic materials, eddy currents, and motion are compared with dynamic test results for a ball-type solenoid. Flexibility of the software allows one to apply it to any type of PWM solenoid actuator and any desired excitation profile
