China nema stepper motor suppliers tells you step motor detailed history summary.
China is not a lot of electrical engineering, industrial control, mathematics, systems, advanced control of the strong professional? Abroad in low-power occasions, but also the use of stepper motor, such as some industrial equipment, industrial production equipment, printers, photocopies, speed printing machine, bank automated teller machine. In addition to the above mentioned Rotary Encoder, the printer also uses the photoelectric code tape or the induction code tape to cooperate with the DC motor to realize the closed loop linear displacement control. In the past, CNC machine tools were realized with high torque stepper motor, and powerful companies now also use AC motor to drive CNC machine tools, which is the main gap in driving equipment, aC motor is a foreign control theory and Engineering Analysis and application capability, advanced control theory as software, written in the controller. Generally speaking, stepper motor is a simple open-loop control, low requirements for the user, not suitable for high-power occasions. In satellite, radar and other applications, China in the late Cultural Revolution, on the production of Torque Motor, on the production of Ring Torque Motor, in high-quality control occasions, sometimes can not use stepper motor. China is not a lot of electrical engineering, industrial control, mathematics, systems, advanced control of the strong professional? These questions should be answered accurately by them, I am unemployed. Step Motor subdivision control, in the early reform and opening up, China has been basically mastered, this and AC motor vector control, much less difficult.
