Patented solution
Project description
Due to the many possible shapes and topologies they can embrace, slotless windings represent a substantial potential for improvement. Indeed, windings are a key part of electrical machines and their enhancement directly affects the performances of electrical machines. A new patented solution for slotless winding involving non-constant wire sections and an optimised shape enables the increase of the performances of motors by 25% compared to traditional windings. With the help of constantly improving additive manufacturing technologies, new manners of designing and manufacturing electrical machines are now possible.
