The adaptation of stepper motors to fill roles normally suited for continuous-motion machines is increasingly popular. The advantages include low cost, simplicity of operation, and a holding ability not easily achieved or even possible with other types of motors.
For this project we examined the motion of a stepper motor in order to get an idea of how to correct for undesirable velocity fluctuations. To determine the level of improvement it is useful to have a systematic way of quantifying motion quality. To fulfill this need, we developed a linear-slide test platform on which a motor can be mounted and tested. We also created a software solution that performs the duties of test control and data processing.
