Abstract
An electric circuit for an electric motor. The electric motor having has at least one stator with at least three coils and a rotor with at least two magnetic poles. The motor is operable by the electric circuit at least in the following two states: a) in a first state, the coils can each be energized with different currents of a three-phase system and the rotor can be set into rotation about an axis of rotation; b) in a second state, the coils can be energized with an in-phase alternating current.
