Abstract:
A submersible electric motor has feature to enhance thermal conductivity from the motor interior to the exterior. The motor has a cylindrical housing and a stator rigidly mounted within housing. A rotatable rotor is located within the stator. A gap formed between the stator's outer diameter and the inner wall of the housing is filled with a high thermal conductivity material to improve heat transfer from the motor. The remaining portion of the housing may be filled with a dielectric lubricant that has lesser thermal conductivity than the high thermal conductivity material.
