The comparison of active and reactive magnetic couplers

In this paper there are researched and compared three types of cylindrical magnetic couplers (MC): active MC, reactive MC with yoke and reactive MC without yoke. The comparison is made by the couplers' maximal mechanical torque, which is their main characteristic. The torque is calculated applying software QuickField by designing the magnetic field. The QuickField is based on the finite elements method. It is researched and recommended a new type of reactive MC.
