Subdivision drive control of stepping motor
The stepping motor is limited by its own manufacturing process. For example, the size of the step angle is determined by the number of rotor teeth and running beats, but the number of rotor teeth and running beats are limited. Therefore, the step angle of the stepping motor is generally large and fixed, with low step resolution, lack of flexibility, vibration at low frequency, and higher noise than other micromotors, Make the physical device easy to fatigue or damage. These shortcomings make the stepper motor can only be used in some occasions with low requirements. For occasions with high requirements, it can only adopt closed-loop control, which increases the complexity of the system. These shortcomings seriously limit the effective utilization of the stepper motor as an excellent open-loop control component. Subdivision driving technology effectively overcomes these shortcomings to a certain extent.
Stepping motor subdivision driving technology is a driving technology developed in the mid-1990s, which can significantly improve the comprehensive performance of stepping motor. In, American scholars first proposed the control method of step angle subdivision of stepping motor at the annual meeting of American incremental motion control system and devices. In the following twenty years, stepping motor subdivision drive has been greatly developed. Gradually developed into a fully mature in the 1990s. The research on subdivision drive technology in China is almost the same as that in foreign countries.
In the mid-1990s, China's economy witnessed great development. It is mainly used in industry, aerospace, robotics, precision measurement and other fields, such as photoelectric theodolite for tracking satellite, military instrument, communication and radar. The wide application of subdivision drive technology makes the phase number of motor not limited by step angle, which brings convenience to product design. At present, in the subdivision drive technology of stepping motor, chopper constant current drive, instrument pulse width modulation drive and current vector constant amplitude uniform rotation drive control are adopted, which greatly improves the operation accuracy of stepping motor and makes stepping motor develop in the direction of high speed and precision in the field of medium and small power applications.
