Abstract: An electric motor is provided, including a stator having two electromagnetic poles diametrically opposite each other, a rotor including a rotor core configured for being rotatably mounted with a shaft for rotation relative to the stator. The rotor core is formed by stacking a plurality of laminations each of which has a central hole and a plurality of generally radially extending teeth. The stator and the rotor have geometric attributes such that: R1=G*0.9968, wherein G is defined as thickness of a field yoke, and R1 is defined as a distance from an outside edge of a central hole to bases of the teeth. A compressor assembly is also provided that employs the present motor.
