Title:
ROTATING ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2020/213052
Kind Code:
A1
Abstract:
In this rotating electric machine, by providing a cylindrical inner housing 1i inside of a cylindrical outer housing 1o, a coolant flow path is formed between the two. One end of the inner housing 1i is fixed to the outer housing 1o by press fitting (or shrink fitting), and the other end of the inner housing 1i is fixed to the outer housing 1o by fastening with a bolt 5. In other words, the inner housing 1i is fixed to the outer housing 1o at both ends. The shrink fitting area Y between the inner housing 1i and a stator core 2s and the (press fitting or shrink fitting) fixing area X between the outer housing 1o and the inner housing 1i do not overlap in the axial direction of the rotation shaft O.
