Design of Stepping Motor control system based on LabVIEW

Abstract

By design the program and control the corresponding hardware devices, to design a Stepping motor control system to control the rotation of the stepping motor.The software part of this system is programmed based on LabVIEW, and communicates with the ELVIS II platform via USB port of the computer, so as to carry out a series of control on stepping motor.The hardware part consists of four parts, including the computer, the NI ELVIS II platform, the drive and the stepping motor.Through the LabVIEW program in the computer input the rotation angle.The rotation angle information is transmitted from the computer hardware interface to the NI ELVIS II platform and generates corresponding electrical signal.The electrical signal is transmitted to the driver and drives the Stepping motor to perform the corresponding rotation angle and control the rotation direction.The system test shows that the rotation angle is larger, the actual rotation error is smaller, and the frequency coefficient of stepping motor is larger, the actual rotation error is smaller.In addition to controlling the stepping motor, this system could be used in the production line and machine processing operation control.
