Abstract

The invention provides a rotary electric machine having full rectification, easy to manufacture and having excellent durableness. The rotary electric machine (10) includes a stator, a passage (13), an inlet opening (23), an outlet opening (24), and a partition (3). The stator has an outer periphery. The passage is provided around the outer periphery. A cooling medium (M) is to flow through the passage. The inlet opening (23) is connected to the passage. The cooling medium (M) is to be supplied to the passage via the inlet opening. The outlet opening (24) is connected to the passage. The cooling medium is to be discharged from the passage (13) via the outlet opening. The inlet opening and the outlet opening divide the passage into a longer passage and a shorter passage shorter than the longer passage. The partition (3) is provided in the shorter passage and comprises an elastic material to contact with an inner surface of the shorter passage (3) so as to restrict a flow of the cooling medium.

Description

technical field [0001] The invention relates to a rotating electric machine. Background technique [0002] A rotating electrical machine including a stator and a case housing the stator is used in a hybrid vehicle or the like. For example, a rotating electric machine has been proposed in which a refrigerant flow path is formed between a stator and a housing (for example, refer to Patent Document 1). [0003] In a rotating electric machine having a flow path for refrigerant, a rectification structure such as a partition member that defines the flow direction of the refrigerant may be provided in the flow path (for example, refer to Patent Document 2). [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Patent Laid-Open No. 2006-296005 [0007] Patent Document 2: Japanese Patent Laid-Open No. 2014-140276 [0008] The problem to be solved by the invention [0009] However, in the aforementioned techniques, due to dimensional fluctu...
