DOWNHOLE MOTOR

Motor Assembly 

Downhole motor rotor is manufactured from high quality alloy steel, while s-rotor is made  of rubber. High force and tearing strength of the rubber stator allows the tool to run in the  high temperatures (about 180 ℃ ) and high oil mud condition. All these benefits help to  maintain effective operation. We produce the downhole motor with an external coating on the motor rotor that gives  the tool a much longer service life.

Cardan Shaft Assembly 

The function of cardan shaft is to convert planetary motion into fixed constant rotation of  drive shaft, to transmit torque and speed from motor on the drive shaft and to the bit.

Drive Shaft Assembly 

The driveshaft assembly converts the eccentric motion of the rotor into concentric rotation  for the bearing assembly. It also accommodates any angle set on the adjustable bent  housing (or fixed bend housing) and carries the thrust load from the rotor caused by the  pressure drop across the power section. The drive shaft assembly are forged using superior alloy steel, it gives the shaft assembly  good strength and toughness and also greatly improve the anti-fatigue capacity during  the rotating movement, thus giving the downhole motor a much longer service life.Tianhe Downhole motors come in sizes ranging from Φ43mm to Φ286mm.
