Title:
DYNAMO-ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2020/158389
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a dynamo-electric machine with which it is possible to inhibit vibration of a frame and a bearing, and which has excellent manufacturability. The dynamo-electric machine according to the present invention comprises: a stator (2); a rotor (1) disposed on the radially inner side of the stator (2), the rotor (1) being provided with a rotary shaft (10); a bearing (16) for supporting the rotary shaft (10); an intermediate frame (15) for supporting the stator (2); and a stator frame (8) for supporting the bearing (16) and the intermediate frame (15). The stator frame (8) comprises pedestals (83) at the two widthwise end sections of the bottom part thereof. The pedestals (83) each comprise an upper surface (83a) positoned higher than the bottom surface of the stator frame (8). The intermediate frame (15) is fixed to the upper surfaces (83a) of the pedestals (83).
