Due to the limitations of its own manufacturing process, such as the size of the step Angle is determined by the number of rotor teeth and the number of running beats, but the number of rotor teeth and the number of running beats is limited, so metal planetary gearbox The step Angle of wholesale is generally large and fixed, the resolution of the step is low, the lack of flexibility, the vibration at low frequency operation, and the noise is higher than that of other micromotors, which makes the physical device easy to fatigue or damage. These shortcomings make metal planetary gearbox wholesale can only be applied in some occasions with lower requirements, and can only take closed-loop control for higher requirements, increasing the complexity of the system. These shortcomings seriously limit metal planetary gearbox wholesale as an efficient use of excellent open loop control components. Subdivision drive technology to some extent effectively overcome these shortcomings.

metal planetary gearbox wholesale subdivision drive technology is a drive technology developed in the middle of the decade that can significantly improve the comprehensive performance of metal planetary gearbox wholesale. The control method for step Angle subdivision of metal planetary gearbox wholesale was first proposed by an American scholar at the Annual Meeting of Incremental Motion Control Systems and Devices. In the following two decades, the metal planetary gearbox wholesale subdivision drive has been greatly developed. Gradually developed to full maturity in the 1990s. The research on subdivision driving technology in China starts at the same time as abroad.
In the mid-1990s to a greater development. Mainly used in industry, aerospace, robotics, precision measurement and other fields, such as tracking satellite photoelectric theodolite, military instruments, communications and radar and other equipment, the wide application of subdivision drive technology, so that the phase number of the motor is not limited by the step Angle, which brings convenience to product design. At present, on the subdivision drive technology of metal planetary gearbox wholesale, chopper constant current drive, instrument pulse width modulation drive, current vector constant amplitude uniform rotation drive control stop, and greatly improve metal planetary gearbox wholesale operation precision, so that metal planetary gearbox wholesale in the field of medium and small power applications to high speed and precision direction.
Initially, the phase current control of metal planetary gearbox wholesale is realized by hardware, usually using two methods, using multiple power switch current supply, current superposition on the winding, this method makes the power tube loss is less, but because of the number of channels, so the device is more, the volume is large.
First, the pulse signal is superimposed, and then linearly amplified by the power tube to obtain the step current, the advantage is that the device used is less, but the power tube power consumption is large, the system power is low, if the tube works in the nonlinear region will cause distortion, due to its own insurmountable shortcomings, so the two types of methods are rarely used.
