Electric motor for a small electric device
First Claim
1. An electric motor for operating a small electric device, comprising:
- at least one first oscillatory motor component;
an inductor for producing a magnetic field;
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);
at least one second oscillatory motor component; and
a second magnet arrangement including a second permanent magnet configured to generate a force for activating a translatory oscillating movement (L) of the at least one second oscillatory motor component in y-direction;
wherein 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 exclusively as a righting moment for the rotatory oscillating movement (R) to maintain the oscillatory movement without any additional mechanical return springs; and
wherein the translatory oscillating movement (L) is perpendicular to the rotating axis (z) of the rotatory oscillating movement (R).

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).
