Publication number: 20230412031Abstract: An electric machine includes a rotor extending along an axis and a stator lamination stack radially spaced from the rotor. The stator lamination stack has circumferentially spaced teeth defining gaps therebetween. The electric machine also includes a coil winding disposed in the gaps between the circumferentially spaced teeth and a guard plate disposed at one of the first and second stator ends. The guard plate extends radially away from the axis and includes a plurality of teeth guards extending radially, with each of the teeth guards aligned with one of the teeth of the stator lamination stack to electrically insulate the coil winding from the teeth of the stator lamination stack. The plurality of teeth of the stator lamination stack extend radially inward toward the axis and the teeth guards of the guard plate extend radially inward toward the axis.Type: ApplicationFiled: August 30, 2023Publication date: December 21, 2023Inventors: Christopher Joel Maurus, Jeffrey Carter, Tyler Ransom Garrard
