Patent ID: 8829754

Claim:
An electric rotating machine, 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 coil conductors are wound on the stator so that two stator magnetic poles may be formed by two coil units of a phase wound around stator teeth within a range of 360 electrical degrees subtended by the magnetic poles of the rotor; each of the two coil units forming the stator magnetic poles spans an electrical angle equal to or less than 180 electrical degrees; each coil unit has multiple turns within a range narrower than 180 electrical degrees; the coil turns of the two coil units forming the two stator magnetic poles are laid out such that they may not overlap each other; the coil conductors are so wound that adjacent stator magnetic poles exhibit opposite magnetic polarities; and two coil units forming two adjacent stator magnetic poles are staggered by 180 electrical degrees from each other.
