Variable Frequency Speed Regulating Asynchronous Motor,YJ19,YJ19A AND YJ19B Motor

YJ19,YJ19A AND YJ19B Motor

YJ19,YJ19A AND YJ19B Motor are cage variable frequency speed regulating asynchronous motors developed for AC-DC-AC electric drive oil drilling machine in China. They can drive rotary table, winch and slurry pump and sone other unit of the oil-drilling machine. The motors' installation dimension is the same as that of imported DC oil drilling machine. They take explosion-proof strcture with heaters, pressure switches and  auxiliary switches installed in them. The main characteristics are: Large torque, wide range constant power speed regulating, free maintenance, high universality, efficiency and reliability. The terminal mode of each motor is different.
