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.
