Introduction YJ13YJ13A for Oilfield Use
     YJ13 And YJ13A motor are squirrel cage variable frequency speed regulating asynchronous motor developed for the first AC-DC-AC electric drive oil-drilling machine. They take international advanced insulation processes and special measures protecting the bars from braking. The center height and installation dimension of the motors are the same as that of imported DC oil drilling motor. Their main features are: large torque, wide range constant power speed regulating, free maintenance, high universality, efficiency and reliability. YJ13 and YJ13A motor can be used as slurry pump motor, rotary table motor or winch motor of AC drive oil drilling machine.
