YJ21 motor

YJ21 motor is squirrel cage variable frequency speed regulating saynchronous motor developed for AC-DC-AC electric drive oil drilling machine. The motor takes international advanced insulation processes and special measures protecting bars from breaking. Its centerline height and installation dimension are the same as that of imported DC oil drilling machine. The motor's main features are: large torque, wide range constant power speed regulating, free maintenance, high universality, efficiency and reliability. YJ21 motor can be used as slurry pump motor, rotary table motor or winch motor of AC drive drilling machine
