    Abstract: A brushless motor is provided including a rotor rotating around a center axis and a stator including a stator core and stator teeth radially extending from the stator core forming stator slots therebetween. Each stator tooth includes a radial main body and a tooth tip extending substantially laterally from an end of the radial main body opposite the stator core, and stator windings are wound around the stator teeth. Winding retention wedges are axially received within the slots, each winding retention wedge comprising: a first portion received within gaps formed between tooth tips of adjacent stator teeth, and a second portion received at least partially between adjacent stator windings to apply a force substantially in a range of a radially-inward direction to a lateral direction to the adjacent stator windings.
