Title The design of stepper motor drive system
Abstract
Stepping motor is an the electrical component to turn pulse signal into electrical mechanical angular displacement , it can achieve good positioning accuracy under the condition of complex feedback loop to servo system, and has high performance price ratio,easy control etc. It is a wide range of application in economical numerical Opening access control positioning system in civil and industrial use . Therefore the research and development of the hybrid stepping motor has the important theory significance and practical value.
It is a new stage of stepping motor driver development that the use of single-chip microcomputer controls the driving power of stepping motor control in recent years. The use of single-chip stepping motor control is not only flexible, convenient, easy to implement, easy to program,save the cost, but also has the advantages of simple structure, good reliability and strong anti-interference ability, so it can be widely used in the industrial field. this paper explains the characteristics and basic principle of hybrid stepping motor, and the development status and trend of the drive technical research,controlled deceleration or Acceleration and Forward or reverse of the stepping motor.
Keywords Stepping motor Driving system Single chip microcomputer Forward or reverse deceleration or Acceleration
