Laser cutting machine servo motor and the working principle of stepper motor

by：Transon 2020-11-01

Servo positioning by pulse laser cutting machine, and basically can understand it, servo motor to receive a pulse, will rotate one pulse of the corresponding point of view, so as to realize the displacement, because, the function of the servo motor itself has a pulse, so each rotation Angle of a servo motor, send out the corresponding number of pulses, in this way, and the servo motor to accept pulse forming the echo, or closed loop, as a result, the system will know how many pulses sent to the servo motor, how much charge pulse back again at the same time, in this way, can be very precise control of the motor rotation, so as to realize accurate positioning, can reach 0. 001mm。 Stepper motor is a kind of discrete movement of the device, it has the nature of the contact and the modern digital control technology. In the current domestic digital control system, stepping motor is widely used. With the emergence of digital ac servo system, ac servo motors are increasingly used in the digital control system. In order to adapt to the development trend of digital control, motion control systems mostly adopt stepper motor or all-digital ac servo motor as the executive motor. Although both similar on control mode ( Pulse sequence and direction signal) Elastic coupling, but in the use of performance and applications where there is a larger difference.
