Scroll Compressor Having A Single Phase Induction Motor With Aluminum Windings

A scroll compressor, the scroll compressor comprising:

• a compression unit;
• and
• a single phase motor driving the compression unit, the single phase motor comprising:
• a stator having a stator core that includes a stack height chosen to be a height between 4.25 inches and 4.75 inches, the stator core defining plurality of slots positioned radially about an interior of the stator core and windings located within the plurality of slots, the windings include a main winding and a start winding and each of the main winding and start winding are formed from a conducting wire that includes aluminum;
• a slot fill ratio chosen to be a ratio between 0.64 and 0.72;
• and
• a rotor disposed concentrically within the stator, the rotor including an outer periphery and aluminum bars evenly spaced about the outer periphery, a number of aluminum bars chosen between 34 and 36.
