A high-speed universal motor running at over 10,000 or even over 20,000 rpm includes a non-rubbing water repellent sleeve that protects the bearings from moisture damage. Rather than having a sliding contact seal that can quickly wear out under such high speeds, the sleeve is made of material having a low solid surface energy so that the seal material itself repels waters on its own. TEFLON is the preferred material, which is relatively soft, so to prevent the compressibility of the seal from affecting the axial positioning of parts on the motor shaft, the seal is installed such that the seal does not contribute to the critically precise positioning of the shaft and the parts mounted to it. In some embodiments, for example, the relatively soft seal simply overlies a much stiffer, accurately machined metal spacer.
