【 摘 要 】

This paper describes the design and implementation of microstepper motor drive and a control system for two-phase hybrid stepper motor. Based on LM3S6965 arm processor, this paper proposes an approach to subdivide the step to microstep with required number of steps for stepper motor to improve positioning accuracy. Sine/cosine microstepping method is used to adjust the current in each winding of the stepper motor. This paper describes the running of motor at different speeds by changing the number of samples per rotation and position control by number of samples. The experiment showed that the system for controlling stepper motor can be used stably and reliably.
