摘要： An electric submersible pump is provided which has improved vibrational characteristics relative to conventional electric submersible pumps. The improved electric submersible pumps comprise an electric motor mechanically coupled to a pumping section. The improved vibrational characteristics of the electric submersible pump are attributed to the presence of one or more rotor bearings selected from the group consisting of herringbone patterned rotor bearings, pressure dam rotor bearings, circumferential groove rotor bearings, and combinations of two or more of any of the foregoing rotor bearings.
