2. Servo control - Wikipedia

   en.wikipedia.org/wiki/Servo_control

   Servo and receiver connections A diagram showing typical PWM timing for a servomotor. Servo control is a method of controlling many types of RC/hobbyist servos by sending the servo a PWM (pulse-width modulation) signal, a series of repeating pulses of variable width where either the width of the pulse (most common modern hobby servos) or the duty cycle of a pulse train (less common today ...

3. Servo (radio control) - Wikipedia

   en.wikipedia.org/wiki/Servo_(radio_control)

   A hobby digital servo is controlled by the same "standard pulse servo mode" pulses as an analog servo. [1] Some hobby digital servos can be set to another mode that allows a robot controller to read back the actual position of the servo shaft. Some hobby digital servos can optionally be set to another mode and "programmed", so it has the ...

   The grey/green cylinder is the brush-type DC motor. The black section at the bottom contains the planetary reduction gear, and the black object on top of the motor is the optical rotary encoder for position feedback. Small R/C servo mechanism. 1. electric motor 2. position feedback potentiometer 3. reduction gear 4. actuator arm

5. Servomotor - Wikipedia

   en.wikipedia.org/wiki/Servomotor

   A servomotor (or servo motor or simply servo) [1] is a rotary or linear actuator that allows for precise control of angular or linear position, velocity, and acceleration in a mechanical system. [ 1 ] [ 2 ] It constitutes part of a servomechanism , and consists of a suitable motor coupled to a sensor for position feedback and a controller ...

6. Radio-controlled model - Wikipedia

   en.wikipedia.org/wiki/Radio-controlled_model

   Off-the-shelf servos respond directly to servo control pulse trains of this type using integrated decoder circuits, and in response they actuate a rotating arm or lever on the top of the servo. An electric motor and reduction gearbox is used to drive the output arm and a variable component such as a resistor "potentiometer" or tuning capacitor ...

7. Servo drive - Wikipedia

   en.wikipedia.org/wiki/Servo_drive

   A servo drive receives a command signal from a control system, amplifies the signal, and transmits electric current to a servo motor in order to produce motion proportional to the command signal. Typically, the command signal represents a desired velocity, but can also represent a desired torque or position.
