Rotary motor unit, power generator unit, wind power generation system, rotary motor and power generator

Abstract

The utility model provides a rotary motor unit; and in a structure which is provided with a rotor capable of supporting a rotating shaft part with a single arm, an assembly procedure which can inhibit an assemble procedure that the rotating shaft part is supported on the rotor from becoming complicated. The specific scheme is as follows: a power generator unit (1) (a rotary motor unit) comprises the rotor (31), a stator (21), and a clamp (41) which also serves as a cover; the rotor (31) comprises a rotor iron core (32) and a rotating shaft support part (33) which can support the rotating shaft part (2a) with the single arm; the stator (21) comprises a stator iron core (22) which is over against the rotor iron core (32) in a radius direction; the structure of the clamp (41) which also serves as the cover is as follows: when the rotating shaft part (2a) is not supported on the rotating shaft support part (33), the rotor (31) is restricted to move to the radius direction; and simultaneously, and when the rotating shaft part (2a) is supported on the rotating shaft support part (33), the clamp becomes the cover which covers the rotor iron core (32) and the stator iron core (22).

Description

technical field [0001] The present invention relates to a rotating electrical machine unit, a generator unit, a wind power generation system, a rotating electrical machine, and a generator, and more particularly to a rotating electrical machine unit, a generator unit, a wind power generation system, a rotating Motors and generators. Background technique [0002] Conventionally, there is known a rotating electric machine unit including a rotor capable of supporting a shaft portion in a cantilevered state (for example, refer to Patent Document 1). [0003] The above-mentioned Patent Document 1 discloses a built-in motor (rotary electric machine unit), which includes: a rotor (rotor), including a rotor core, which supports an output shaft (rotation shaft portion) in a cantilever shape; The stator cores facing each other in the radial direction; and the motor cover covering the rotor core and the stator core.

AI Technical Summary

Problems solved by technology

[0005] However, in the motor described in the aforementioned Patent Document 1, it is necessary to consider not to make the rotor core and the stator core contact when the output shaft is not supported by the rotor, and there is a problem that the assembly process becomes complicated due to this consideration.
