[0020] based on Figure 1 to Figure 5 The terminal block according to the first embodiment of the present invention will be described.

[0021] The rotating electric machine 1 is used for a rotating electric machine (rotary electric machine) such as an electric motor (electric machine) and a generator (generator). The rotating electric machine 1 is, for example, a motor having three-phase poles.

[0022] like figure 1 As shown, the rotating electrical machine 1 has: a housing 2 ; a stator 3 accommodated in the housing 2 ; and a rotor (not shown) disposed inside the stator 3 . The stator 3 is formed in a cylindrical shape, and multi-phase coils including U-phase, V-phase, and W-phase are wound in slots formed at equal angular intervals on the inner peripheral side. The stator 3 has a plurality of (three in this embodiment) strong electric wires (lead wires) 4 drawn from the coils of the respective phases. In addition to the strong wires 4 of the U-phase, V-phase, and W-phas...

Abstract

A terminal block (10) of a rotating electric machine (1) is provided with: a terminal block main body (13); high-current electrical wire connecting sections (17) for connecting high-current electricalwires (4) of the rotating electric machine (1); a plurality of neutral wire connecting sections (18) for connecting neutral wires (5) of the rotating electric machine (1); and a bus bar (21) that connects the neutral wire connecting sections (18) to each other.

Description

technical field [0001] The present invention relates to a terminal block of a rotating electric machine. Background technique [0002] Conventionally, rotating electric machines used as electric motors, generators, etc. are known (for example, refer to Patent Document 1). [0003] In a rotating electric machine having a parallel circuit of a plurality of star connections (Y connection), there are cases where neutral points of circuits are connected to each other. In this case, since the potential of the neutral point is equalized between the circuits, an effect of making the magnetic flux uniform between the circuits can be obtained. [0004] In the rotating electrical machine described in Patent Document 1, the neutral points of circuits are connected using arc-shaped bus bars. The bus bar has a connection portion to a neutral-point-side lead wire of the rotating electrical machine, and is arranged at a coil end portion of the rotating electrical machine. [0005] Patent...
