Abstract:
An electric motor for operating a small electric device is disclosed. The electric motor includes at least one first oscillatory motor component; an inductor for producing a magnetic field; and a first magnet arrangement including a first permanent magnet that generates a force for activating a rotatory oscillating movement (R) of the at least one first oscillatory motor component around a rotating axis (z). The at least one first oscillatory motor component and the first magnet arrangement are configured such that a magnetic reluctance torque acting between the first oscillatory motor component and the first permanent magnet operates as a righting moment for the rotatory oscillating movement (R).
