    Abstract: A power tool includes a housing having a large diameter rear portion and a narrow diameter nosepiece. An end effector is rotatably coupled to the housing. A holder with a substantially annular holder body is received over the nosepiece and non-rotatably coupled to the housing. A substantially annular cover having at least one transparent surface, and an internal annular groove, is received at least partially inside the holder body, and non-rotatably and axially fixed with respect to the holder. A substantially annular printed circuit board is received at least partially inside the annular groove in the cover, and non-rotatably and axially fixed with respect to the cover. A plurality of lighting elements is operatively connected to the printed circuit board and radially disposed about the printed circuit board. The lighting elements are aligned with the at least one transparent surface so as to illuminate a workpiece.

    Abstract: A stator assembly for a brushless DC motor includes a stator core including stator poles and an outer surface, at least one magnet wire wound on the poles forming stator windings, and a bus bar including a non-conductive mount arranged on the outer surface and conductive terminals. Each conductive terminal includes: a main portion mounted on the non-conductive mount substantially parallel to the longitudinal axis of the motor, a tang portion folded over the main portion from a first longitudinal end of the main portion, and a connection tab at a second longitudinal end of the main portion. At least a contact portion of the at least one magnet wire is wrapped around the tang portion and fused to make an electric connection to the conductive terminal, and the connection tab makes electric contact with a wire supplying electric power to the motor.
