Abstract
A stator assembly for a BLDC motor includes a stator core, at least one magnet wire wound on poles of the stator core, an end insulator mounted on an end surface of the stator core, a non-conductive mount member mounted on the outer circumferential surface of the stator core, and conductive terminals mounted on the non-conductive mount member. Each conductive terminal includes: a main portion mounted on the non-conductive mount, a tang portion extending from a first longitudinal end adjacent the end insulator and folded over the main portion, and a connection tab extending angularly from a second longitudinal end. A contact portion of the magnet wire is wrapped around the tang portion and fused to make an electric connection to the conductive terminal.
