Patent ID: 7915778

Claim:
An electric motor, comprising: a rotor having plural magnetic poles along its periphery; and a stator having teeth that are disposed opposite to the periphery of the rotor; wherein, the stator includes two stator magnetic poles of the same phase, each of which is formed by a tooth, a first coil turn, and a second coil turn coupled in series with the first coil turn and having a polarity opposite to a polarity of the first coil turn, within a range of 360 electrical degrees subtended by the magnetic poles of the rotor; each of the first coil turn and the second coil turn is wound so as to span an electrical angle less than 180 electrical degrees in a circumferential direction; and a tooth constituting a part of a stator magnetic pole of the other phase is disposed between the first coil turn and the second coil turn.
