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 and conductive terminals. Each conductive terminal includes: a main portion and a tang portion extending from a first 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. The tang portion has a smaller lateral width than the main portion and is folded over the main portion to capture the contact portion of the at least one magnet wire. A power wire supply electric power to the motor is coupled to the conductive terminal proximate the second longitudinal end of the main portion.
