  • Patent number: 11876404
    Abstract: The electric machine includes a rotor and an internal stator operatively coupled to the rotor. The internal stator further includes a back iron having a bearing and a plurality of teeth, a plurality of ring coils wound around the back iron, a central hub, and a plurality of connectors that connects the central hub to the back iron. The back iron is made of a first material and at least one connector is made of a second material that is different from the first material.
    Type: Grant

  • Publication number: 20230283136
    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.
