YZ08 and YZ08A DC motors 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, and its performance is equivalent to GE752BR3.
