Abstract
The present invention may provide a motor including a shaft, a rotor coupled to the shaft, and a stator disposed to correspond to the rotor, wherein the rotor includes a rotor core and magnets coupled to the rotor core, the rotor core includes holes which pass through the rotor core in an axial direction and in which the magnets are disposed, an outer circumferential surface of the rotor core includes grooves extending in the axial direction, and a center of the groove does not overlap the hole in a radial direction from the shaft.
Claims9
A motor comprising:
- a shaft;
- a rotor coupled to the shaft;
- and
- a stator disposed to correspond to the rotor,
- wherein the rotor includes a rotor core and magnets coupled to the rotor core,
- the rotor core includes first holes and second holes in which the magnets are disposed,
- an outer circumferential surface of the rotor core includes grooves extending in an axial direction, and
- the groove is disposed between the first hole and the second hole in a circumferential direction,
- wherein the first hole and the second hole each include a first curved surface, an outer circumferential surface of the rotor core includes a second curved surface formed between two virtual straight lines extending from a center of the rotor core to pass through both ends of the first curved surface of the hole, and the first curved surface and the second curved surface are concentric.
