Introduction：
YJ19 YJ19A YJ19B
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.
