Abstract

Provided are a power supply unit and a rotary electric machine. A power supply unit (1) comprises: a plurality of power supply bodies (11) electrically connecting to each of conductors (107) constituting a coil (106) wound for each of a plurality of phases; and a resin holding part (21) formed of a resin material and integrally connecting and holding the plurality of power supply bodies (11). Theresin holding part (21) of the power supply unit is provided with: outside protection sections (22) surrounding the power supply bodies (11); and a connection section (23) connecting two adjacent outside protection sections (22). The power supply unit makes it possible to reduce the influence of thermal stress by setting a thickness dimension L (23) of the connection section (23) to be the same asa thickness dimension L (22) of the outside protection sections (22).

Description

technical field [0001] The present invention relates to a power supply unit for connecting coils of each phase of a rotating electric machine to the outside, and a rotating electric machine having the power supply unit. Background technique [0002] In a rotating electrical machine, lead wires are connected to the coils of each phase, and electric power is supplied and received (electric power transmission) between the outside and the coils of each phase through the lead wires. [0003] For example, Patent Document 1 discloses a structure in which corresponding lead wires are integrated with each other by insert molding.
