Abstract
A stator for an electric machine comprising a rotor and stator poles. At least one partial amount of stator poles each comprises a pole winding and a permanent magnet unit. A first magnetic flux induced by the permanent magnet unit is superimposed by a second magnetic flux is an electric voltage is applied to the pole winding or an electrical current is injected into the pole winding. A recess is arranged in the permanent magnet unit, which recess faces the rotor. An electric machine comprising a stator according to the invention, wherein the rotor is designed to change a magnetic resistance of a magnetic circuit, which extends through a permanent magnet unit of stator poles of the stator, according to the position of the rotor.
