An electric drive motor that is intended for a vehicle, in particular for a motor vehicle, includes a stator and a rotor with at least one pole pair, wherein each pole of a respective pole pair has a magnet arrangement having at least one buried magnetic layer. The drive motor is characterized in that each pole has a number of magnetic flux influencing groups, each of which has a number of air-filled recesses, which are not assigned to a magnet of a respective magnetic layer for purposes of flux conductance.
