Motor

A motor comprising:

• rotor assemblies configured to be rotated within a stator and stacked one on another in an axial direction to be relatively rotatable in relation to each other,
• wherein each rotor assembly includes:
• a first rotor including a first outer rotor having a hollow shape, in which a plurality of first magnet members are mounted on an outer circumferential surface of the first outer rotor and a first support recess, which is radially recessed, is formed on a hollow inner circumferential surface of the first outer rotor, a first inner rotor inserted into the first outer rotor, in which a first latch is formed on an outer circumferential surface of the first inner rotor to be inserted into the first support recess, and first elastic support provided in the first support recess so as to elastically support the first latch to one side in a circumferential direction;
• and
• a second rotor including a second outer rotor having a hollow shape, in which a plurality of second magnet members are mounted on an outer circumferential surface of the second outer rotor and a second support recess, which is radially recessed, is formed on a hollow inner circumferential surface of the second outer rotor, a second inner rotor inserted into the second outer rotor, in which a second latch is formed on an outer circumferential surface of the second inner rotor to be inserted into the second support recess, and second elastic support provided in the second support recess so as to elastically support the second latch to the other side in a circumferential direction,
• wherein the first rotor and the second rotor are arranged to deviate from each other so as to form a skew angle.
