<p>The invention relates to an electric motor (10,48,68,100,128) for operating a small electric device having a first oscillatory motor component (22,54,70,140) and an inductor (24,56,74,130) for producing a magnetic field. A first magnet arrangement has at least one first permanent magnet (14,16,18,20,50,52,76,134,136,138) that in interaction with a magnetic field produced with the inductor (24,56,74,130) generates a force for activating a rotatory oscillating movement of the first oscillatory motor component (22,54,70,140) around a rotating axis. According to the invention, the first oscillatory motor component (22,54,70,140) and the first magnet arrangement are designed in such a way that the magnetic reluctance torque acting between the first oscillatory motor component (22,54,70,140) and the at least one permanent magnet (14,16,18,20,50,52,76,134,136,138) of the first magnet arrangement acts as a righting moment for the rotatory oscillating movement. The invention also relates to a small electric device having an electric motor according to the invention, a method for operating an electric motor according to the invention and a method for manufacturing an electric motor according to the invention.</p> |
