Electric axial flux machine with housing having openings

An electric axial flux machine, comprising:

• a stator, and a rotor, wherein the rotor includes a rotor shaft with a rotor body arranged on the rotor shaft in a non-rotatable and non-displaceable manner;
• wherein the stator includes a first annular disk-shaped stator member and a second annular disk-shaped stator member arranged coaxially with respect to one another and to the rotor shaft and axially spaced apart from one another with the rotor being arranged therebetween, and wherein a first air gap is formed between the first annular disk-shaped stator member and the rotor and a second air gap is formed between the second annular disk-shaped stator member and the rotor, wherein the rotor has a plurality of receiving slots distributed equidistantly over a circumference and extending radially through the rotor body, in each of which a rotor magnet is fixed, wherein the axial flux machine further includes a cylindrical ring-shaped motor housing which encloses the first annular disk-shaped stator member, the rotor and the second annular disk-shaped stator member in the axial direction, wherein the cylindrical ring-shaped motor housing has a plurality of openings distributed over a circumference of a lateral surface thereof;
• wherein each one of the plurality of openings in the lateral surface of the motor housing has a substantially rectangular contour, an axial extent of which is greater than a circumferential extent, and
• wherein each one of the plurality of openings in the lateral surface of the motor housing completely covers the rotor body in its axial extent.
