    摘要： Rotor disk (100) for an axial flux machine, the rotor disk (100) comprising:
    - magnets (103) being attached to the front side (107) of a back iron (101);
    - the back iron (101), provided as a wound coil comprising multiple turns (106) and being mounted on an inner hub (104),
    wherein:
    - the back side (108) of the back iron coil (101) is, at least partially, exposed; and
    - the rotor disk (100) comprises a retention system providing structural strength to the back iron coil (101), the retention system comprising
    o a retention ring (102) placed around the back iron coil (101), thereby retaining the turns (106) of the back iron coil (101) by compressing the turns (106) in radial direction,
    and/or
    ∘ one or more radially extending welds (1100), thereby retaining the turns (106) of the back iron coil (101) by welding consecutive turns to one another.

    摘要： A motor rotor apparatus is provided. The motor rotor apparatus includes a rotor core (201) and a bonding element (401). The bonding element (401) is embedded in the rotor core (201). The rotor core (201) is provided with a first air sub-groove (301a), and the first air sub-groove (301a) includes a first tooth (3011a) and a first slot (3011b). The bonding element (401) includes a second tooth (4011a) and a second slot (4011b). The first tooth (3011a) is engaged with the second tooth (4011a), and the first slot (3011b) is engaged with the second slot (4011b). A structure that the bonding element (401) is engaged with the first air sub-groove (301a) in the rotor core (201) can effectively absorb centrifugal force generated when a rotor is rotated at a high speed. This significantly reduces stress on a rotor magnetic bridge, ensures robustness of the rotor that rotates at a high speed, and increases a speed of a motor as much as possible.
