A study on kinetic characteristics of a cylindrical moving coil linear DC motor for a vibrator

A cylindrical moving coil linear DC motor has been developed for a vibrator which is driven at a high frequency with a short stroke. The actuator is supposed to be driven using resonances of spring plates which are placed at the end of the permanent magnet and the armature, respectively. This paper describes the investigation of stroke to frequency characteristics as the kinetic characteristics of the actuator.
