Abstract
A core for an electric machine includes a core component having a plurality of core teeth defining a plurality of core slots between adjacent core teeth of the plurality of core teeth. The plurality of core slots are receptive of one or more windings. A coolant flowpath through the core component is formed through at least one core tooth. The at least one core tooth has one or more coolant tube banks and one or more mixing chambers arranged in an alternating pattern along the at least one core tooth.
