Tips
The RC servo motor is widely used in automatic control occasions. Its output torque, rotation speed, command update frequency, etc. standardize the working performance of the radio control servo motor. Normally, the operation of the RC servo motor depends on the unique pulse command high-level time width of it, and has nothing to do with the frequency of the pulse command. Therefore, the function of the pulse waveform that controls the RC servo motor and the PWM waveform that controls the operation of the motor are different. There is a drive circuit board inside the RC servo motor to ensure a proportional relationship between the output angle and the width of the pulse command. The output angular speed of RC servo motor depends on various factors such as the internal mechanical structure of it, the performance of the motor, and the working voltage. Since the speed of the RC servo motor has nothing to do with the command, in essence, it is not a linear model. When it rotates at a larger angle, its dynamic nonlinearity is more obvious.
