Abstract
A stator assembly for a brushless DC motor includes a stator core defining poles and having an outer surface, at least one magnet wire wound on the poles forming phases, 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 is arranged to makes electric contact with a wire supplying electric power to the motor.
