Choosing the Right Encoder for a Servo Motor

Connected to specific software, Scott measures the accuracy of the encoder counting – it was found to be counting correctly and in factory specifications.

Encoders are special sensors that capture position information and relay that data to other devices. They are used to determine the position, velocity and direction of a motor shaft or other mechanical motion. They provide information required for the precise control of a variety of applications, such as positioning a rotary table, pick and place, machine assembly, packaging, robotics and more.

Encoders determine position using one of three technologies: optical, magnetic or capacitive.

The most accurate of the standard styles of encoders are the optical encoders. When choosing an optical encoder, it’s important that the encoder
