Abstract: Stepper motors are widely used in various space orientation and execution mechanisms. The basic principles of stepper motors and typical drive control circuits were introduces. The development of electronic components used in space stepper motor drive control, the iterations of drive circuits, and the characteristics of component localization were overviewed and summarized. A forecast on the future development of stepper motor drive circuits was given, providing reference for the design of stepper motor drive circuits in aerospace applications.

Key words: stepper motor, drive circuit, component localization, aerospace applications
