Rotating status of the traveler of a ring spinning system has previously been analyzed by many researchers with emphasis primarily on the property of the mechanism, twist propagation in a yarn, and theoretical analysis of the result. Little attention has been paid to physical measurements of rotating parameters and other validation tests. In this paper, we put forward a measurement method of rotating speed to investigate the traveler’s speed variations and other dynamic behaviors. Spinning yarn experiments are conducted by normal, exceptional subjects, and spinning position for comparison in which associated rotating speed is measured and analyzed. The results indicated that in the traverse of the ring bar of a spinning process, system signal after noise filtering fluctuated about 0 V, while the range of signals produced by the traveler was about 1.5 V for all of statuses and the distance of pulse was stability. The maximum amplitudes of signals increased gradually along with the ring bar went up. On the contrary, the maximum amplitudes of signals decreased gradually along with the ring bar, which also went down.
