Claim 2:
3. The motor of claim 2, wherein:
the rotor includes a cylindrical rotor core and a plurality of magnets disposed to surround an outer circumferential surface of the rotor core,
each magnet has an inner circumferential surface in contact with the outer circumferential surface of the rotor core, and, when an angle formed by the outer circumferential surface of the rotor core divided by the number of the magnets is referred to as a first angle, the magnet has a second angle formed between a first extension line and a second extension line, which extend from two end points of the inner circumferential surface of the magnet to a center point of the rotor core on transverse cross sections of the rotor core and the magnet, and
a ratio of the second angle to the first angle ranges from 0.92 to 0.95.
