Abstract
Apparent rotational angular acceleration exist in the stepper motor operation processing, the stepper motor torque angle characteristics were described and the mathematical model of motor are constructed; The actual angular acceleration of stepper motor on single-step operation is measured by self-developed rotating angular acceleration sensor, the experimental results show that the angular acceleration fluctuations of stepping motor on three single clap operation are little greater than on six clap operation, and there are return oscillations of motor on three single clap operation are obviously more than on six clap operation; Finally, the experimental phenomenon reasons are analyzed, and the corresponding conclusions are obtained.
