Abstract: The present invention relates to electric machines (EM), such as electric motors and electric generators, which convert electrical energy into mechanical energy and mechanical energy into electricity respectively, including linear motion EMs, curvilinear motion EMs and rotary (turning) motion EMs. More particularly, the present invention relates to an EM induction method and device, said induction system comprising two main magnetic coupling subsystems, for example a subsystem comprising permanent magnets and a subsystem comprising electromagnets. Thus, EM induction system comprises at least one special feature chosen from the group consisting of the following kinds (a)-(c): (a) it is configured as a multiple-vector (MV) system and it is configured such as to provide multiple-vector coupling; (b) at least one of the permanent magnets is selected from the group consisting of: a closed-laminated permanent magnet; and a ?-shaped anti-symmetric group of permanent magnets.
