Embodiment Construction
[0048] Hereinafter, embodiments of the present invention will be described using the drawings and the like.
[0049] Prior to the description of the radial gap type rotating electrical machine of the present invention, the structure of the conventional radial gap type rotating electrical machine will be described. Figure 12A It is a schematic diagram showing the structure of a conventional radial gap motor (inner rotor type), Figure 12B Yes Figure 12A Cross-sectional view. Such as Figure 12A as well as Figure 12B As shown, the radial gap motor 200 has a generally cylindrical shape. The stator core (stator core) 11 is arranged in the axial center portion of the housing 10 in which radiating fins are provided on the outer portion.
[0050] The stator core 11 is fitted with a stator coil 12 wound around its teeth, and a rotor including a permanent magnet 13 and a rotor core (magnetic core) 14 is rotatably held inside the stator via a bearing 18. The bearings 18 are held by end b...

Abstract
Provided are: a radial-gap-type rotary electric machine that uses an amorphous metal that makes it possible to achieve high efficiency and has excellent producibility; a production method for the radial-gap-type rotary electric machine; a production device for a rotary electric machine teeth piece; and a production method for a rotary electric machine teeth member. This radial-gap-type rotary electric machine is characterized by comprising: a rotor (102) that has a rotary shaft, an inner-circumferential-side rotor core (31a) that can rotate around the rotary shaft, and an outer-circumferential-side rotor core (31b) that is arranged on the outer circumferential side of the inner-circumferential-side rotor core and can rotate around the rotary shaft; and a stator (101) that is provided between the inner-circumferential-side rotor core (31a) and the outer-circumferential-side rotor core (31b). The radial-gap-type rotary electric machine is also characterized in that permanent magnets (22,23) are provided on an outer-circumferential-side surface of the inner-circumferential-side rotor core (31a) and / or an inner-circumferential-side surface of the outer-circumferential-side rotor core(31b). The radial-gap-type rotary electric machine is also characterized in that the stator (101) has a stator core that includes teeth that comprise laminates in which amorphous metal foil strips areheld by the friction therebetween.
Description
Technical field [0001] The present invention relates to a radial gap type rotating electric machine and a method for manufacturing the same, a manufacturing device for a gear plate for a rotating electric machine, and a method for manufacturing a tooth member for a rotating electric machine, and in particular to a radial gap type rotating electric machine using amorphous metal in the core The manufacturing method thereof, the manufacturing device of the gear piece for a rotating electric machine, and the manufacturing method of the gear member for the rotating electric machine. Background technique [0002] Rotating electric machines (motors) used as power sources for industrial machines and for driving motor vehicles are required to increase efficiency. To increase the efficiency of the motor, it is a common design to use low-loss materials among the materials used, or to use permanent magnets with high energy products. [0003] Motor losses mainly include copper loss, iron loss,...
