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. A bottom surface portion of a busbar holder body portion includes a bearing holder holding a bearing defined therein, and includes resistors and capacitors defining a portion of a Hall IC circuit arranged thereon. The Hall IC circuit is arranged to input and output electrical signals to or from Hall ICs. An upper surface portion includes sensor holders each holding a separate one of the Hall ICs defined therein. A connector portion is arranged to project radially outward from the busbar holder body portion. The sensor connection busbars and each of the coil connection busbars are arranged one above another along an axial direction.
