碩士 === 元智大學 === 電機工程學系 === 91 === Due to intermittence, a step motor vibrates frequently while acting. Furthermore, misstep is possible when excitation magnetism changes phase in the high frequency. Both the cases will cause the motor to operate abnormally. However, these situations can be improved if operating frequency is chosen appropriately. Currently, the method of trial and error is adopted to get the applicable frequency. But, it is time consuming and hard to obtain acceptable solution! In the near future, the best operating frequency for a motor can be decided from optimal technique. To avoid large amount of expense of physical experiments, computer simulation can be used to study and analysis. Using the simulation, technique, it is necessary to realize the motion track of a motor. In other words, the values of characteristic parameters of the motor, such as inertia mass, coefficient of damping, … etc, must be available beforehand. Unfortunately, most of manufacturers can’t provide the whole parameters we needed. In this study, we propose two methods to solve the problem of finding the required parameters of the motor. The results based on these two methods and the data acquisition capability of a step response instrument for measuring the step motor will be compared and investigated in this thesis. The practical values of parameters can thus be estimated according to the step response of the motor if analytical values of parameters are identical with practical values. For users, this is an easy strategy to determine a motor performance. Especially, a motor will raise its performance, improving vibration and misstep while operating, and it is expected that the cost in the research and development of new step motors will be reduced thereafter.
