Abstract
In a busbar unit, which is a distributing device arranged to supply electrical currents to coils, a busbar holder is arranged to support coil connection busbars and sensor connection busbars. Conductor wire connection portions of the coil connection busbars are exposed on both axial sides and welded to a conductor wire defining the coils. The sensor connection busbars are combined with a plurality of electronic components to define a Hall IC circuit designed to output and receive electrical signals to or from Hall ICs. Sensor connection portions of the sensor connection busbars are exposed on both axial sides, and welded to terminals of the Hall ICs. Electronic component connection portions of the sensor connection busbars are exposed on both axial sides, and welded to the electronic components.
