Abstract: A rotor for an axial flux motor with a disk-shaped rotor plate, a plurality of permanent magnets and a holding structure. The disk-shaped rotor plate has a plurality of magnet receptacles, which are distributed in the circumferential direction and introduced into the rotor plate in the axial direction. The magnet receptacles are each defined by four inner side surfaces of the rotor plate. The plurality of permanent magnets are arranged in the magnet receptacles and are each defined by four outer side surfaces. A first groove is introduced into at least one of the inner side surfaces, and a second groove is introduced into at least one of the outer side surfaces. The first and the second groove are arranged and formed in such a way that they jointly form a channel portion in which the holding structure for fixing the permanent magnets in the rotor plate is arranged.

Abstract: The present disclosure relates to a rotor 10 for an axial flux motor 1. The rotor 10 comprises a rotor wheel 100, a plurality of permanent magnets 50 and a holding structure 60. The rotor wheel 100 comprises disk-shaped main body 110 and a plurality of arms 120. The disk-shaped main body 110 defines an inner circumference 111 and an outer circumference 114. The plurality of arms 120 protrude from the outer circumference 114 radially outwards to a respective arm tip 123. The plurality of arms 120 is circumferentially distributed on the outer circumference 114. The plurality of permanent magnets 50 is distributed circumferentially about the outer circumference 114 and arranged circumferentially between the plurality of arms 120. The holding structure 60 is attached to the rotor wheel 100 and to the plurality of permanent magnets 50 to hold the plurality of permanent magnets 50 in position.
