Abstract:
This busbar unit comprises: busbars of three phases connected to coils of three phases; and external terminals of three phases that are made from a different material from the busbars of three phases, are connected to the busbars of three phases, and are electrically connected to a power supply source. Each of the external terminals of three phases comprises: a terminal body; a busbar-side connection part that is connected to a busbar of one phase from among the busbars of three phases; and a power-supply-source-side connection part that is electrically connected to the power supply source. For at least two terminals from among the external terminals of three phases, the lengths of conduction routes in the terminal bodies through which current flows between the busbar-side connection parts and power-supply-source-side connection parts are different.
