Abstract
A bar-wound stator, which is connectable to a plurality of fixed terminal points, includes a plurality of stator teeth and a plurality of magnet wires. Each of the plurality of magnet wires has a winding portion wound about at least one of the plurality of stator teeth and a junction portion extending away therefrom. A plurality of flexible leads each have a first portion ultrasonically welded directly to a respective one of the junction portions of the plurality of magnet wires. A second portion of each of the plurality of flexible leads extends flexibly away from the first portion and is configured for attachment to a respective one of the fixed terminal points.
