DES-YZ14 and DES-YZ14A motor are squirrel cage variable frequency speed regulating synchronous motors designed for the first AC-DC-AC electric drive oil-drilling machine in China. These two kinds of motors can drive the winch, rotary table, slurry pump and some other unit of oil drilling machine. Their installation dimension is as same as that of imported DC oil drilling motor. DES-YZ14 and DES-YZ14A motor have explosion-proof structure, and the heater, pressure switches and auxiliary switches are installed in them. Their main features are as follows: large torque, wide range constant power speed regulating, free maintenance, high universality, efficiency and reliability. Facing from the driving end, the terminal out of DES-YZ14 motor is on the left side, and from DES-YZ14A motor is on the right side.
