Abstract: A permanent magnet rotor core includes a plurality of rotor poles circumferentially-spaced about a central axis and including a first rotor pole and an adjacent second rotor pole that each include an outer wall, and wherein the rotor core includes a rotor diameter. The rotor core also includes a plurality of radial apertures alternately-spaced with the plurality of rotor poles. The rotor core also includes a first protrusion extending from the first rotor pole into a first radial aperture of the plurality of radial apertures positioned between the first rotor pole and the second rotor pole. The rotor core further includes a second protrusion extending from the second rotor pole into the first radial aperture such that a circumferential opening is defined between the first protrusion and the second protrusion. The opening extends a first length of between approximately 0.052% and approximately 0.058% of the rotor diameter.

Abstract: A hydrodynamic bearing assembly includes a first member including a first engaging surface. The first member is stationary in a non-operating mode of the bearing assembly and rotates about an axis in an operational mode of the bearing assembly. The first member includes a first bore and a shaft positioned within the first bore and including an end surface. The hydrodynamic bearing assembly also includes a second member including a second bore and a second engaging surface positioned adjacent the first engaging surface. The second member is stationary in both the non-operating mode and the operational mode of the bearing assembly. The hydrodynamic bearing assembly further includes a spacer member positioned within the second bore and is configured to engage the first member to define a first gap between the first engaging surface and the second engaging surface in the non-operational mode.

Abstract: An axial flux electric machine comprises a rotor assembly configured to rotate about an axis of rotation. A stator core is coupled to the rotor assembly. The stator core comprises a stator core base and a plurality of circumferentially-spaced stator teeth extending from the base in a direction parallel to the axis. Each stator tooth of the plurality of stator teeth comprises a top surface, a pair of opposing circumferential sides, and a chamfered portion defined at an intersection of the top surface and each of the pair of opposing sides. The chamfered portion facilitates reducing an amount of torque ripple produced by the axial flux electric motor.

Abstract: An electric machine includes a housing having an air intake, an air outlet, and defining an air passage therein. The air passage includes a first channel extending from the air intake in a radial direction and a second channel extending in the radial direction to the outlet. The electric machine further includes a motor assembly positioned within the housing that includes a shaft that rotates about a rotational axis that is generally perpendicular to the radial direction. The electric machine further includes an electronics assembly within the housing interior and a heat sink positioned at least partially within the air passage and thermally connected to the electronics assembly. Operation of the motor assembly draws an ambient airflow into the air passage in the radial direction through the air intake, directs the airflow along the heat sink, and exhausts the airflow through the air outlet in the radial direction.
