Electric machine with elevated power density

Abstract

The invention relates to an electric machine comprising either a circular-ring-cylindrical stator and a circular-cylindrical rotor which is arranged rotatably inside the stator, or a circular-cylindrical stator and a circular-ring-cylindrical rotor, which is arranged rotatably outside the stator, there being an air gap formed between the stator and the rotor. The rotor comprises a magnetically conductive rotor body and at least one pair of magnets arranged adjacently within the rotor body, wherein magnet axes leaving identical poles of the magnets of the magnet pair intersect one another on the side of the magnets of the magnet pair facing the stator. The rotor body has at least one recess in a region extending in the circumferential direction and radial direction of the rotor and defined by the magnet pair.
