Abstract: An electrical machine includes a rotor, a stator, and a winding mounted within a housing. The rotor includes a rotor core mounted to a shaft and a plurality of blades extending radially away from the rotor core. Each blade of the plurality of blades is curved axially along the rotor core. The stator includes a stator core and a plurality of teeth extending from the stator core toward the rotor core to define a plurality of slots between successive teeth. The winding is wound through at least two slots of the plurality of slots. The stator is mounted radially relative to the rotor. The housing includes a front wall, a back wall, and a radial sidewall mounted between the front wall and the back wall to define an enclosure. A radial inlet aperture wall is formed circumferentially through the radial sidewall to form an opening through the radial sidewall.
