The anti-deformation ability and rigidity of this down-hole motor’s rubber is enhanced and can enduring high pressure for single grade motor; torque and output power improved more than 50% than conventional motors. The thickness of the rubber is uniform, which reduces the sensitivity to temperature; performance of heat dissipation is good; slows the aging process and extend the life of the stator.
