Personnel engaged in the work of step motor research design know, electricity opportunities because of low resolution is limited by its own manufacturing process exists, lack of flexibility, when running in low frequency vibration, noise,

Higher shortcomings, and subdividing motor drive control, would be able to overcome these shortcomings in a certain extent.
the stepping motor is the electrical pulse signal into angular displacement or linear displacement of open loop control motor, is a modern digital process, the main components of control system, has extensive application. In the case of the overload, planetary gear motor speed, stop position depends only on the pulse signal frequency and pulse number, and not affected by load change, when the stepper driver receives a pulse signal, it is driving a stepper motor according to set the direction of a fixed point of view, called & other; Interval Angle & throughout; , its rotation is based on the Angle of the fixed step by step. Can be controlled by controlling the pulse number of angular displacement, so as to achieve the purpose of accurate positioning; As well as by controlling the pulse frequency to control motor rotation speed and acceleration, so as to achieve the purpose of regulating.
so how about scenes of this planetary gear motor driver need to control?
at the beginning of the stepper planetary gear motor phase current control is implemented by hardware, and control methods mainly include one or two, one is to take multiple power ( Refers to the object of the work done in a unit time) Switch power supply, current and overlay on the winding current, in order to reduce loss of power tube. Another kind is to the pulse signal superposition, then through power tube linear amplifier, current step. More than one kind of method because the route is more, so the electric drill speed reducer, large volume, the second method the advantage, although there is a electric drill speed reducer ( Explanation: can overwhelm the favorable situation of each other) , but also there is a high power tube power, low system power of these shortcomings.
it is because of the early motor subdivision drive control technology not only there are a lot of disadvantages, so the two methods are phased out, to now are mainly adopt chopping constant current drive, pulse width modulation driving, constant amplitude current vector even rotation drive control.
stepper motor driver is a kind of electrical pulses into angular displacement of the actuator. When stepping drive receives a pulse signal, it drives stepper motor according to set the direction of a fixed point ( Called & other; Interval Angle & throughout; ) , its rotation is based on the Angle of the fixed step by step. Stepper motor driver in order to further improve the drive systems of high frequency response, frequency boost power driver interface can be used up.
the interface provided by the winding voltage and the operating frequency of the motor into linear relationship. Its main circuit is actually a switch regulated power supply, use of frequency - Voltage converter, drive pulse frequency conversion into dc level, and the level to control switch regulated power supply input, this constitutes a frequency feedback power driver interface.
by this technical application can greatly improve step motor running running accuracy ( C) And applications in the field of medium and small power motor, presented the high-speed and motors this two obvious trends.
