A motor includes: a stator having 12n teeth at equal intervals in a circumferential direction of the motor, with a coil being formed on each of the teeth, where n is a natural number; a rotor having magnetic poles, number of magnetic poles being one of 2n, 10n and 14n, where n is a natural number; a three phase first coil group formed by star-connecting the coils formed on the odd-numbered teeth; and a three phase second coil group formed by delta-connecting the coils formed on the even-numbered teeth, connected to the three phase first coil group in parallel.
