Electric disk motor for driving a wheel rim

An electric disk motor for operation in a wheel rim of a vehicle, the electric disk motor comprising:

• a first rotor comprising a rotor ring, which comprises
• a first ring-shaped surface;
• a second ring-shaped surface located parallel to the first ring-shaped surface on an opposite side of the rotor ring, the first and second ring-shaped surfaces each extending perpendicular to an imaginary axis of rotation through a center of the rotor ring;
• a first plurality of permanent magnets regularly arranged on a circular path in corresponding circular segments and extending through the rotor ring from the first ring-shaped surface towards the second ring-shaped surface, wherein north-south alignments of permanent magnets of the first plurality respectively run parallel to the imaginary axis of rotation, and respective ones of adjacent permanent magnets comprise north-south alignments rotated by 180° to each other;
• a first tube section extending from an outer periphery of the rotor ring concentrically to the imaginary axis of rotation away from the first ring-shaped surface, the first tube section comprising a second plurality of permanent magnets regularly arranged on an inner side of the first tube section,
• wherein the first plurality of permanent magnets is numerically identical to the second plurality of permanent magnets,
• wherein north-south alignments of permanent magnets of the second plurality respectively run perpendicular to the imaginary axis of rotation, and adjacent ones of the permanent magnets of the second plurality each comprise north-south alignments rotated by 180° to one another, and
• wherein respective different poles of the corresponding permanent magnets of the first plurality of permanent magnets and of the second plurality of permanent magnets in the respective circular segment are located at a predefined angle to one another,
• a stator comprising a first stator ring, which comprises
• a first ring-shaped surface;
• a second ring-shaped surface located parallel to the first ring-shaped surface on an opposite side of the first stator ring, the first and second ring-shaped surfaces each extending perpendicular to the imaginary axis of rotation through a center of the first stator ring and of the first rotor, wherein the imaginary axes of rotation of the first stator ring and the first rotor are identical;
• a third plurality of electromagnets within the first stator ring,
• wherein the third plurality of electromagnets magnets is numerically smaller than the first plurality of permanent magnets,
• wherein electromagnets of the third plurality of electromagnets each comprise a separate curved core, and
• wherein one pole of one of the respective electromagnets of the third plurality of electromagnets points towards an outer circumferential periphery of the first stator ring, and a correspondingly other pole of the respective one of the electromagnets of the third plurality of electromagnets,
• wherein a first gap is located between respective poles of the electromagnets of the third plurality of electromagnets pointing towards the periphery of the stator ring and the second plurality of the permanent magnets on the inner side of the first tube section of the first rotor, and
• wherein a second gap is located between the poles of the electromagnets of the third plurality of electromagnets pointing towards the first surface and the first plurality of permanent magnets, wherein the second gap is located opposite a plane of the corresponding poles of the electromagnets, so that the rotor is rotatable freely with respect to the stator ring.
