Servo driver with phase memory for linear cutting machine

The utility model discloses a servo driver with phase memory for a linear cutting machine. The device comprises a device body, one end of the interior of the device body is fixedly connected with a servo motor through a screw, one end of the servo motor is fixedly connected with a pulse encoder, the middle of the other end of the servo motor is rotationally connected with a rotating shaft, and oneend of the pulse encoder is connected with a PWM generator in a clamped mode. The device is reasonable in design; convenient use, a PID controller, a PWM generator and an amplifier are arranged; theamplifier can improve the signal receiving and transmitting efficiency; a PID controller and a PWM generator of a general automatic control technology are conveniently adopted to realize a function oflarge-amplitude speed regulation and a function of high-speed load which are the same as those of an imported servo motor. According to the utility model, the moving shaft lead screw on the linear cutting machine can be conven
