Most hobby servos of this type are restricted to a certain range of motion (usually 180 degrees) because the position encoder is a simple potentiometer connected to the output shaft.

Position encoders are sensors that, when used in industrial settings, produce critical motor information such as speed and position. The encoder delivers data for display or data that may serve as ...

A 12-bit encoder tells the microcontroller where the motor is and the output drivers can handle over 3 A of motor current. The microprocessor is a tried-and-true ATmega328.

The Icon PID Position Controller is designed to work seamlessly with the Icon H-Bridge module. When used with a brushed dc motor and quadrature encoder, the two devices form a highly versatile ...

This excerpt from the book "Electric Motors and Drives: Fundamentals, Types and Applications" examines servo motors and both analog and digital position control.

The Rock-Tenn paperboard mill in Aurora, Ill., automated the positioning and tensioning of belts on its conveyor system with low-cost motors and drives paired with absolute encoders.
