US 12,556,055 B2 · Electrical interconnector and motor including the same

Abstract

A stator of an electrical machine including stator windings, a stator insulator, connectors, and a printed circuit board. Each of the stator windings is wound by magnet wire on a stator lamination core such that the stator has a plurality of magnet wires. The stator insulator is formed of an insulative material and has a ring structure and connector receivers. The connectors include legs such that the legs of each connector are coupled to a corresponding one of the connector receivers by snap-fit engagement. Each of the connectors electrically connects to single or multiple magnet wires. The printed circuit board is coupled to an input power line and is electrically connected to each of the connectors such that the printed circuit board is electrically connected to the magnet wire of each of the stator windings.
