Abstract
A hydrodynamic bearing assembly includes a first stationary component, a shaft coupled to the first stationary component, and a second stationary component coupled to the shaft opposite the first stationary component. The hydrodynamic bearing assembly also includes a rotating component coupled to the shaft between the first stationary component and the second stationary component. The rotating component includes a first end surface including a first diameter and an opposing second end surface including a second diameter that is greater than the first diameter.
