Latest Patents

One of Graham Sentance's latest patents is focused on an electrical machine designed specifically for vehicles. This invention includes a rotor that can be rotated about an axis of rotation, defining an axial direction. The machine features 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 patent involves a method for producing a stator for an electric machine. This method includes 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 is 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 it remains free from the second plastic mass, allowing for the formation of a cooling duct.
