Document Type and Number:
WIPO Patent Application WO/2013/024609
Kind Code:
A1
Abstract:
A three-phase alternating-current motor, wherein, when U-, V-, and W-phase stator coils (3, 4, 5) are concentrated-wound via an insulating bobbin (8) onto a plurality of teeth parts provided to a stator core (2), the stator coils (3, 4, 5) of each phase are wound so that the coil height gradually increases from the inside-diameter side to the outside-diameter side of the insulating bobbin (8) in relation to a coil space on the side of a slot (6), and, in a space formed on the inside-diameter side of the insulating bobbin (8) and on the axially directed outside of the stator coils (3, 4, 5), there is housed a neutral point (9) at which connecting wires (11 through 16) of the stator coils (3, 4, 5) of each phase and the distal ends (3A, 4A, 5A) thereof are star-connected along the space.
