ABSTRACT:
A submersible motor includes a stator section along the entire length of rotor sections attached to the motor shaft, and a non-magnetic rotor bearing and sleeve assembly between each rotor section, with the rotor bearing being releasable but normally interconnected with the stator to prevent its rotation relative to the sleeve which rotates with the motor shaft.
