Abstract
An example method of producing an electric machine is described herein. The method can include providing the electric machine. The electric machine can include a rotor and a stator, where the stator includes a magnetic core and a stator winding. Additionally, the magnetic core can include a plurality of teeth defining a plurality of slots between adjacent teeth. The stator winding can also include a first portion arranged inside a slot and a second portion arranged outside the slot. The method can further include optimizing, using a computing device, a geometry of the first portion of the stator winding, where the first portion of the stator winding in the provided electric machine has the optimized geometry.
