Abstract: Based on virtual instrument technology, a motor speed control and measurement system was designed and developed using LabVIEW software, which can improve working conditions, reduce costs, and increase efficiency. Keywords: LabVIEW; motor; measurement and control Motor measurement and control occupies a very important position in industrial control systems. Traditional motor measurement and control systems mainly use ordinary pointer instruments, requiring manual reading, recording, data processing, curve plotting, and documentation. This results in slow measurement and control speed, inaccurate data, and complex data processing and analysis, making it difficult to meet the requirements of modern development. Motor measurement and control systems are generally divided into two parts: data acquisition and control and human-machine interface. Current automatic control systems often use various solutions such as single-chip microcomputer control, industrial PC control, and PLC control. We developed and designed a new type of motor speed control and measurement system using virtual instrument technology. This system uses an ordinary PC as the host and the graphical visual testing software LabVIEW as the software development platform to measure and control the motor's operating speed, collect data, and process, store, and display it. The equipment is cost-effective, convenient, and flexible to use, suitable for factories, enterprises, and teaching. LabVIEW is a general-purpose virtual instrument development software developed by National Instruments (NI). It integrates all the communication functions of hardware and data acquisition cards that meet protocols such as GPIB, VXI, PCI, RS-232, and RS-485. It contains a rich function library and is a powerful and flexible graphical software. It uses the graphical programming language G to create source code in flowcharts. This programming method emphasizes the actual signal processing process, making programming simple and debugging convenient. A program designed with LabVIEW consists of two parts: the front panel, which is the instrument's interface, and the block diagram, which implements the instrument's internal design and is the true "core" of the program.
