Zusammenfassung: | A synchronous reluctance motor includes a stator and a rotor. The rotor is configured to rotate relative to the stator about a rotational axis. The rotor is spaced apart from the stator to define an air gap between the stator and the rotor and includes a rotor core defines an outermost rotor surface and an innermost rotor surface opposite the innermost rotor surface. The rotor core includes a plurality of ribs separating rotor cavities from each other and includes a plurality of rotor bridges separating the air gap and the rotor cavities. Permanent magnets are each disposed in one of the rotor cavities. The magnet surface area of the permanent magnets is less than cavity surface area of the rotor cavities. Each of the permanent magnets is adjacent to the outermost rotor surface to maximize magnetic saturation at the ribs and the rotor bridges. |
