Study of a Mini-Actuator with Permanent Magnets
The paper presents an analytical method for the determination of the magnetic force produced by a mini actuator with permanent magnets. The results are compared with those obtained by performing a numerical field analysis with COMSOL Multiphysics, showing a very good agreement. The study reveals that the actuator has two equilibrium points, one of which is stable and the other one unstable.
