Abstract :
The measurement of steady-state and transient load-angle, angular velocity, and acceleration using an optical encoder is described. The accuracy of measurement is assessed, and results are given for the run-up of a three-phase reluctance motor. Accurate values of speed and load-angle are determined, but the measurement of acceleration is more difficult, and significant errors are present for values in excess of approximately 50 mechanical rad/s2. Predicted results for a computer model are in reasonable agreement
