Understanding the encoder resolutionElectronicSpecifier

An incremental rotary encoder can be used to measure rotational direction speed and angular displacement. The encoder generates two output channels as it rotates A and B. Each output is a square wave and in a quadrature encoder the two outputs are 90 deg out of phase. By Jason Kelly Motion Control Design and Applications Engineer CUI Devices

Encoder resolution and accuracy What s the difference

The higher resolution encoder just has the ability to break up that 90 degree movement into much smaller increments. Factors that affect resolution. An encoder s resolution is based on the number of lines (for an incremental encoder) or the pattern (for an absolute encoder) on the encoder disk or scale. Physically resolution is fixed.

Incremental Encoderan overview ScienceDirect Topics

Incremental encoders are the most widely used in motor drive applications. Since the incremental encoder produces a series of pulses as the rotor moves we cannot measure the rotor speed directly from the encoders. Thus we will next discuss a method to estimate the speed from the output pulses of an encoder.
