Abstract

The present invention provides a rotating electrical machine capable of preventing damage to insulating parts and short-circuiting of coils. A rotating electrical machine (1) includes: a stator (5) having a stator core (6) and a coil (7) attached to the stator core (6); a housing (9); and a fastening member (8) having Fix the stator (5) to the housing (9). The housing (9) is formed of a material having a higher coefficient of linear expansion than the stator core (6). A buffer plate (50) is inserted between the fastening portion (40) of the stator core (6) and the contact portion (90) of the housing (9), and the buffer plate (50) and the stator core (6) The friction coefficient of the fastening part (40) is smaller than the friction coefficient of the abutting part (90) of the buffer plate (50) and the casing (9), and the fastening part (40) of the stator core (6) and the casing (9) The coefficient of friction of the abutting portion (90) is equal to or less than that.

Description

technical field [0001] The present invention relates to a rotating electrical machine mounted on an electric vehicle or the like. Background technique [0002] Conventionally, a rotating electrical machine has been used as a power source and a power generation source for vehicles such as a hybrid vehicle. The rotating electrical machine includes a stator. [0003] For example, the rotating electrical machine of Patent Document 1 includes a stator including a stator core and a coil. The stator core is formed in an annular shape by stacking a plurality of annular plates in the axial direction. The coil is surrounded by insulating parts such as a film and insulating paper. The attachment portion of the stator core is fixed to the case (stator support member) with bolts or the like, for example. [0004] The plurality of teeth are provided at intervals in the circumferential direction on the inner peripheral edge of the yoke portion. A slot for accommodating the coil is for...
