ROTARY ELECTRICAL MACHINE

The rotating electrical machine disclosed in the present application provides a rotor shafts (12) supported by bearings (9), (11), a rotor (14) attached to the rotor shaft (12) and rotates with the rotor shaft (12), a stator (3) that surrounds the rotor (14) through a gap (314g) so that the rotor (14) can rotate, a frame (2) that surrounds the rotor (14) and the stator (3), an outer circumference of the stator (3) is attached to an inner circumference of the frame (2), and an annular member provided along the inner circumference of the frame (2) to prevent foreign matter existing at the boundary part between the frame (2) and the stator (3) from moving to a region different from the boundary part, it prevents foreign matter generated in the manufacturing process of the rotating electrical machine, such as shavings of a frame, from being scattered inside the rotating electrical machine.
