Basic knowledge of micro servo steering gear

Micro servo steering gear used in radio amateur model aircraft activity has a long history, and the most widely used, domestic also called "steering gear", meaning is: "the helm control machine". Steering gear is a kind of position servo drive. It is important of the robot, mechanical and electrical system and the model aircraft actuator.It receives a control signal, the output of the Angle, for those who need to Angle changing and can keep control system. Standard of the steering gear has three wires: the power cord (red), earth (black or grey), line (white or orange).Line of the input is a periodic width adjustable square wave pulse signal (PWM), the cycle of square wave pulse signal of 20 ms (that is, the frequency of 50 Hz), when the square wave pulse width change, change the Angle of the steering gear shaft, Angle change is proportional to the change of pulse width, the change of the duty cycle is used to change the position of the steering gear.Visible, the main control unit for direction. Below 180 degrees Angle range servo, for example, the control of pulse width corresponding relations as follows:
