Title:
AXIAL-GAP DYNAMO-ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2015/159332
Kind Code:
A1
Abstract:
This invention reduces the shaft voltage of an axial-air-gap dynamo-electric machine while ensuring high output and high efficiency. Said axial-air-gap dynamo-electric machine comprises the following: a stator (19) comprising a plurality of stator cores (20), each of which comprises a core (21) and a coil (22), arranged in a circle around a shaft; a housing (40), the inside surface of which faces the stator radially; and at least one rotor (30), the surface of which faces the surface of the stator with a prescribed air gap interposed therebetween in the radial direction of the shaft. The rotor has, on the outside thereof, a conductive section (33 etc.) comprising a conductive member. This axial-air-gap dynamo-electric machine has a first region (11) where the inside surface of the housing faces the aforementioned conductive section (33 etc.) radially and a second region (12), closer to the stator than the first region is, that extends to the coil side surfaces that face the rotor. The proportion of connecting wires in the second region is higher than in the first region.
