Latest Patents

Cunningham's latest patents include an electrical machine designed specifically for vehicles. This invention features a rotor that can be rotated about an axis of rotation, defining an axial direction. The machine includes a stator with stator windings, a coolant distribution chamber, and a coolant collecting chamber arranged axially apart. The coolant distribution chamber fluidically communicates with the coolant collecting chamber to effectively cool the stator windings. Additionally, a cooling duct and stator winding are embedded in an electrically insulating plastic for optimal thermal coupling. The stator is designed with stator teeth that extend along the axial direction, spaced apart in the circumferential direction, and bear the stator windings. The insulating plastic is formed from two different plastic masses, enhancing the machine's efficiency.

Another notable patent is a method for producing a stator for an electric machine. This method involves providing a stator with an annular body from which multiple stator teeth protrude radially inward. An intermediate space is formed between adjacent stator teeth, which are encapsulated with a first plastic mass. A stator winding is arranged on a stator tooth and fixed in place by encapsulating it with a second plastic mass. A first mask is introduced into the intermediate space to ensure that part of the space remains free from the second plastic mass, allowing for the formation of a cooling duct.
