    Abstract: A motor includes a stator comprising windings configured to be energized, and a rotor electromagnetically coupled to the stator and configured to turn relative thereto when the stator is energized. The motor also includes a motor controller configured to measure a speed at which the rotor turns, and energize said stator to generate a first torque output at the rotor when the measured speed is below a first threshold. The motor controller is also configured to energize the stator to generate a second torque output at the rotor when the measured speed is at least the first threshold, wherein the second torque output is greater than the first torque output.

    Abstract: A lamination for use in an electric machine stator includes a body having a generally circular outer periphery and a generally circular inner periphery, spaced from the outer periphery and a plurality of spaced apart teeth extending inwardly from the circular inner periphery. Each of said teeth define opposed inner edges thereof. The lamination includes a first pair of tips extending tangentially in opposed directions from the inner edge of one of said teeth and a second pair of tips extending tangentially in opposed directions from the inner edges of another one of said teeth. A tip of the first pair of tips and a tip of the second pair of tips define a first configuration having a first gap therebetween and defining a second configuration having a second gap therebetween. The first gap being substantially less than the second gap.

    Abstract: In one aspect, a centrifugal blower assembly is provided. The centrifugal blower assembly includes a housing defining an interior space and an impeller configured to channel an airflow within the interior space. A motor is coupled to the impeller and configured to rotate the impeller about an axis. The centrifugal blower also includes a plurality of mounting arms. Each mounting arm of the plurality of mounting arms includes a first end coupled to the housing and a second end coupled to the motor. Each mounting arm of the plurality of mounting arms has a cross-sectional profile that comprises a portion of an airfoil shape.
