发明名称 Electric motor
摘要 <p>An electric motor comprising a rotor (1) having plural magnetic poles in the circumferential direction; and a stator (2) whose teeth are disposed opposite to the periphery of the rotor (1), with an air gap interposed between the rotor (1) and the stator (2), wherein the coil conductors (31, 32, 33) are wound on the stator (2) so that two stator magnetic poles (91, 92) may be formed by two coil units of a phase wound around stator teeth within the range of 360 electrical degrees subtended by the magnetic poles of the rotor (1); each of the two coil units forming the stator magnetic poles (91, 92) spans an electrical angle less than 180 electrical degrees; the two coil turns forming the two stator magnetic poles (91, 92) are laid out so that they may not overlap each other; and the coil conductors (31, 32, 33) are so wound that the adjacent stator magnetic poles (91, 92) exhibit opposite magnetic polarities. </p>
