A Measurement Method for Determining Speed of High-Speed Rotating Parts

This paper focuses on determining the speed of a high-speed rotating part, the gear of a starter motor, without disassembling the product. During the design process of the measurement method, the implementation of a machine vision system was chosen. Instead of using high-speed cameras, image acquisition was implemented by using line scan technology. Verification of the measurement data was performed using an asynchronous motor controlled by a frequency converter. The paper presents the measurement method based on image acquisition and summarizes the experiences gained during the testing process.
