ROTATING ELECTRICAL MACHINE FOR INTERNAL COMBUSTION ENGINE

摘要

This rotating electrical machine (10) for internal combustion engine comprises a rotor (21) connected to a rotary spindle of an internal combustion engine (12), and a stator (31) fixed to the body (13) of the internal combustion engine (12). The stator (31) is connected and fixed to a boss part (13a) which extends from the body (13). A radial direction connecting part (71) is provided by the engagement of the protruding part (73a) of the boss part (13a) and the inner cavity (72a) with the stator core (32). The rotating electrical machine (10) is further equipped with a circumferential direction connecting part (81). The circumferential direction connecting part (81) is positioned further to the inside in the radial direction than the outer edge in the radial direction of the stator (31). The circumferential direction connecting part (81) connects the stator core (32) and the body (13) in the circumferential direction of the stator (31). The circumferential connecting part (81) restricts the position of the stator core (32) in the circumferential direction with respect to the body (13). The circumferential connecting part (81) is provided by meshing between notches and protrusions, or by a pin.
