Abstract
Provided herein is a motor including a plastic component; a stationary component having a thrustplate; and a rotatable component having a sleeve and a counterplate, wherein the plastic component is positioned outside the sleeve, and wherein the thrustplate and the counterplate are positioned to form a fluid dynamic bearing (“FDB”) at a top portion of the sleeve. Also provided is a motor comprising a plastic component; a stationary component comprising a thrustplate; and a rotatable component comprising a sleeve; wherein the plastic component is affixed to the sleeve, and wherein the thrustplate and the plastic component are positioned to form a FDB. Also provided is a motor comprising a plastic component; a stationary component comprising an inner component; and a rotatable component comprising the plastic component and a supporting means for supporting the inner component, wherein the inner component and the supporting means are positioned to form a FDB.
