    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.
