1-2. (canceled)
A rotor comprising:
- a rotor core comprising a plurality of grooves formed at regular intervals in a circumferential direction, wherein the number of the grooves is an integer multiple of the least common multiple of numbers of common poles;
- and
- a plurality of magnets separated by reference grooves among the plurality of grooves and disposed on an outer circumferential surface of the rotor core.
A motor comprising:
- a rotational shaft;
- a rotor having a hole in which the rotational shaft is disposed;
- and
- a stator disposed at an outer side of the rotor,
- wherein the rotor comprises a rotor core coupled to the rotational shaft and magnets disposed on an outer circumferential surface of the rotor core,
- the rotor core comprises a plurality of grooves formed at regular intervals in a circumferential direction, and the number of the grooves is an integer multiple of the least common multiple of target numbers of common poles, and
- the magnets are separated and disposed by reference grooves among the plurality of grooves.
