Introduction：
YJ14 YJ14A
YJ14 and YJ14A motor are squirrel cage
variable frequency speed regulating saynchronous 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. YJ14 and YJ14A motor have explosion-proof structure, and the
heater, pressure switches and auxiliary switches are installed in them. Their
main features are as follows: largetorque, wide range constant power speed
regulating, free maintenance, high universality, efficiency and
reliability.Facing from the driving end, the terminal out of YJ14 motor is on
the left side, and from YJ14A motor is on the right side
