OPTIMIZATION OF ACTUATOR WITH PERMANENT MAGNET FROM VIEWPOINT OF THEIR ARRANGEMENT AND TOTAL MASS OF MAGNETIC CIRCUIT

Ivo Doležel – Pavel Karban – Bohuš Ulrych

   Actuators with permanent magnets represent modern and prospective devices with widely controllable parameters as the lift and magnetic force acting on its movable parts. The paper represents an introductory study of such a device with more permanent magnets connected in series. Solution of its mathematical model is illustrated on a typical example whose results are discussed.
