Axial gap type motor generator |
摘要 |
The invention relates to an axial gap dynamo-electric machine comprising a rotor having a revolving shaft supported by a bearing and a magnet for generating a magnetic field, a stator yoke disposed so as to oppose the rotor, and a plurality of teeth being disposed on the magnet-opposed surface of the stator yoke substantially in the shape of a partly removed circle, wherein a removed portion is free of teeth, the partially removed circle having a midpoint at a predetermined point in relation to a center axis of the bearing and opposing the magnet at a predetermined gap. The invention aims to provide an improved axial gap dynamo-electric machine having a structure in which some of the teeth in the stator are missing, to limit inclination of a rotor caused by such missing of the teeth. Therefore, the invention provides that a center of the revolving shaft is deviated from the midpoint of the partly removed circle in a direction away from the removed portion. |
