Abstract: An electrical machine, which may be a motor and/or a generator has a rotor mounted to rotate about an axis. A plurality of magnetic poles are spaced circumferentially around the rotor in the bore. The rotor comprises a shell shaped to provide a toroidal bore centered on the axis. A slit extends circumferentially around the rotor. The slit penetrates through the shell into the bore. The electrical machine also includes a stator that is supported in the bore by one or more supports extending through the slit of the rotor. The stator carries plural windings that are spaced apart around the bore.

Abstract: According to an aspect, a rotor for a Synchronous Reluctance Motor (SynRM) is provided. The rotor core includes alternating layers of radially fabricated flux carrier and flux barrier material, defining flux barriers extending through the core without bridges and/or center-posts. In some embodiments, the alternating layers include layers of permanent magnet (PM) and soft magnetic composite (SMC) material fabricated on, and adhered directly to, the rotor shaft. A corresponding method for manufacturing the SynRM is also provided.
