  • Publication number: 20260031668
    Abstract: A modular stator assembly for an electric machine comprises a plurality of stator pole modules distributed circumferentially, each module including at least one press-formed phase coil. The machine includes a rotor assembly, which may comprise two or more rotors, having permanent magnets. These magnets are positioned to substantially surround each stator pole, with their magnetic fields oriented either in-plane or through-plane. Energizing a phase coil generates a magnetic field, creating a complete magnetic circuit that flows from the stator poles through the surrounding permanent magnets and, optionally, the back iron. This interaction between the stator's magnetic field and the permanent magnets produces torque, causing rotation of the rotor assembly relative to the stator assembly.
