Story Of Servo Motor
What is Servo Motor?
A Servo is a small device that incorporates a three wire DC motor, a gear train, a potentiometer, an integrated circuit, and an output shaft bearing.
Out of the three wires that stick out from the motor casing, one is for power, one is for ground, and one is a control input line.
The shaft of the servo can be positioned to specific angular positions by sending a coded signal. As long as the coded signal exists on the input line, the servo will maintain the angular position of the shaft. If the coded signal changes, then the angular position of the shaft changes.
Applications of Servo Motor:
- In Industries they are used in machine tools, packaging, factory automation, material handling, printing converting, assembly lines, and many other demanding applications robotics, CNC machinery or automated manufacturing.
- They are also used in radio controlled airplanes to control the positioning and movement of elevators.
- They are used in robots because of their smooth switching on and off and accurate positioning.
- They are also used by aerospace industry to maintain hydraulic fluid in their hydraulic systems.
- They are used in electronic devices such as DVDs or Blue ray Disc players to extend or replay the disc trays.
