Abstract:
A single phase induction motor includes a stator core having a stator yoke and a plurality of teeth extending toward a central opening. The plurality of teeth are spaced apart from one another and define multiple slots between the teeth for receiving windings of the single phase induction motor. The stator core includes a high permeability low coreloss (HPLC) steel having a relative permeability of greater than or equal to 3000 at 1.5 Tesla and 60 Hertz, and a coreloss of less than or equal to 1.75 watts/lb at 1.5 Tesla and 60 Hertz. The motor also includes multiple windings located within the plurality of slots and wrapped around the plurality of teeth of the stator core. Each of the multiple windings include aluminum wire. The motor further includes a rotor body located concentrically within the stator core and including an external surface that faces the stator core.
