    40KG RC Servo Motors Details

    Tips: Types of micro RC servo motor

    According different working signal, the micro RC servo motors are divided into Digital servo motor and analog servo motor. Digital servo is a digital transmission, which has strong anti-interference ability and can facilitate two-way communication. It is flexible, reliable and compact. The analog servo is the existing PWM analog transmission, that is, the change of pulse width directly represents the control vector and is easily disturbed.

    In addition, ordinary volt radio control servo motor has operating voltage of 4.8-6V, high volt RC servo motor has operating voltage of 6-12V. The advantages of HV micro servo motor are less heat generation, more sensitive response, and greater torque.
