DC Motor for Oil Drilling Rig

YZ08 and YZ08A DC motor are high power series excited DC motor developed for electric drive oil drilling machine. The international advanced technology has been adopted in it such as Kapton insulation process, main pole coils formed by hot pressing, pressed and welded frame, spiral slot of commutator, reacting brush holder, wire banding etc. The main features of the motors are as follows: plus pressure explosion-proof, high current, large torque, wide range constant power speed regulating, free maintenance, high universality, efficiency and reliability. Their outline installation dimension is strictly in accordance with that of imported DC oil drilling motor. The oil drilling motor can be used instead of the imported one. They can function as slurry pump motor, rotary table motor and winch motor of DC electric drive drilling machine. Facing from the driving end, the terminal out of YZ08 is on the right side, and from YZ08A is on the left side.

The oil drilling motors Yonge manufactured can meet various installing requirements on oil drilling rig. The motors can be divided into two series. One is the YZ DC motor with separate excitation and series excitation, the other is the YJ asynchronous motor with frequency control of motor speed.
 Its rated power can be from 200kw to 1600kw (different grades of rated power can be supplied according to the needs of users). At present, these motors are installed on the drilling rigs with drilling depth from 1000m to 7000m.
