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 hydrodynamic bearing assembly also includes a second member including a 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 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: A motor controller configured to be coupled to a motor that is coupled to a fan is described. The motor controller includes a processor coupled to a memory, and is configured to operate the motor in a first operating mode in which the motor rotates the fan in a first direction at a first speed. The motor controller is further configured to operate the motor in a restriction detection mode in which the motor rotates the fan in a second direction that is opposite the first direction, determine a torque associated with the motor while the motor is rotating the fan in the second direction, determine that the torque is not within a predefined threshold range in the memory, and determine that a restriction exists in a fluid flow path associated with the motor in response to determining that the torque is not within the predefined threshold range.
