Abstract
The invention relates to an electric machine comprising a rotor, a claw-pole stator (11) which surrounds the rotor, and a unit detecting the rotor position. According to the invention, a flux barrier (12) is provided in the area of a sensor (13) of the unit detecting the rotor position in order to block stray fields of the claw-pole stator (11).
