Experimental verification of the one-phase linear actuator with permanent magnets for robotic system applications

In this paper an experimental results of a static and transient characteristics of the linear motor is to be presented. The linear motor consists of the one cylindrical unmovable coil surrounded by a soft ferromagnetic case and a moveable core made from sequence of ferromagnetic and permanent rings. The model of the linear motor is to be presented with mechanical, electrical and magnetic consideration. At the end of this paper the experimental results are presented with focus on static magnetic force and transient response for a series input voltage steps. The aim of this investigation it was to check the static and dynamic characteristics and assume the usability for application in robotic systems.
