Problems solved by technology

[0005] However, in conventional rotating electrical machines, since it is necessary to provide a plurality of lead-out parts for leading out the lead wires to different positions sandwiching the bracket with respect to the axial direction of the shaft, it is not easy to achieve this in the axial direction of the shaft. miniaturization problem

Embodiment

[0018] First, use figure 1 The configuration of the rotating electric machine according to the embodiment will be described. figure 1 It is a schematic longitudinal sectional view of the rotating electric machine according to the embodiment. like figure 1 As shown, the rotating electric machine 1 according to this embodiment includes: a housing 2 ; brackets 3 and 4 ; bearings 5A, 5B; a shaft 6 ; a stator 7 and a rotor 8 ; a position detector 9 ;

[0019] Further, the rotary electric machine 1 is interlockingly connected to the external device 100 via the shaft 6 . Hereinafter, a case where the rotary electric machine 1 is a motor and the external device 100 is a motor load will be described.

[0020] The case 2 is a cylindrical frame, and accommodates the stator 7 and the rotor 8 therein. In addition, in the case 2, the load-side bracket 4 is provided at the load-side opening end, and the load-side bracket 3 is provided at the non-load side opening end.

[0021] As for th...

Abstract

A rotating electrical machine (1, 1A, 1B) includes a cylindrical housing (2, 2B) that houses a stator (7) and a rotor (8), and a position detector (9) that is mounted on an opposite-to-load side of a shaft (6) that rotates together with the rotor (8), the position detector (9) being configured to detect a rotational position of the shaft (6). The rotating electrical machine (1, 1A, 1B) includes a bracket (3, 3A, 3B) that is mounted on an opposite-to-load side of the housing (2, 2B), the bracket (3, 3A, 3B) being configured to support the shaft (6) such that the shaft is rotatable and the bracket (3, 3A, 3B) having an opening portion through which a wire (91) connected to the position detector (9) and a wire (73) connected to the stator (7) are led to the outside.

Description

technical field [0001] The invention relates to a rotating electric machine. Background technique [0002] Conventionally, there is a rotating electric machine that includes a position detector on the opposite-to-load side of the shaft as a rotating electric machine that detects the rotational position of a shaft that rotates together with a rotor. In this rotating electric machine, the space in the casing in which the stator and the rotor are accommodated and the space in which the position detector is installed are blocked by the bracket that supports the shaft. [0003] Therefore, in such a rotating electric machine, it is common (for example, to refer to Patent Document 1) that the lead wires connected to the position detector are led out of the rotating electric machine and the lead wires connected to the stator are drawn out of the rotating electric machine. The lead-out parts are provided at different positions sandwiching the bracket with respect to the axial direct...
