Patent Searching and Data


Title:
DYNAMO-ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2021/186526
Kind Code:
A1
Abstract:
A partition plate (6) positioned in a ring shape around a rotary shaft (5) and used to form a refrigerant channel has a structure in which a plurality of partition plate split bodies (11) made of insulating members are joined in the circumferential direction. Mutually adjacent partition plate split bodies (11) are made to face each other and joined at splitting surfaces (6a), which are circumferential end surfaces. Grooves (13a) formed on each of the splitting surfaces (6a) communicate, and form a single hole (130a), due to the splitting surfaces (6a) of the partition plate split bodies (11) being made to face each other. The holes (130a) have a shape obtained by, e.g., sweeping the shape of the opening thereof in the thickness direction of the partition plate (6). Joining bodies (12a) made of an insulating member are inserted into the holes (130a). A friction force is produced between the joining bodies (12a) and the partition plate split bodies (11), joining the joining bodies (12a) and the partition plate split bodies (11).
