Claim 0:
1. A motor comprising:
a housing; and
a stator disposed in the housing,
wherein the housing includes a body and a plurality of protrusions protruding inward from an inner surface of the body and disposed to be spaced apart from each other in a circumferential direction,
the stator includes a stator core and a coil wound around the stator core,
an outer circumferential surface of the stator core forms a circle at a radius,
the inner surface of the body is spaced apart from an outer circumferential surface of the stator core, and
an inner surface of the protrusion is in contact with the outer circumferential surface of the stator core,
wherein the stator core includes yokes formed in a ring shape and teeth protruding from the yokes in a radial direction,
wherein each of the plurality of protrusions is not disposed in a first width area between two virtual lines each extending along a corresponding one side surface of one of the plurality of teeth of the stator core, plus an additional width at each side of the two virtual lines, the additional width being at least 10 percent of a width of the first width area.
