Precisely tracking speed, acceleration, and position of a motor's rotor is an essential requirement for many motor control applications found in everyday equipment such as fax machines, elevators, and ...

Reading quadrature encoder signals at high speeds (e.g., 1MHz, or, 1m/s with a resolution of 1µm) often requires dedicated hardware. This Design Idea shows a simple scheme to accomplish this function ...

Encoders are widely used in the motion control and automation industry to monitor the position and speed of motors. This information can be used by the motion control electronics to detect if the ...

To attain accurate positioning, a servo system requires a feedback signal to close its feedback loop. Instruments that typically supply the feedback signal include optical encoders, resolvers, and ...

• The new mantra of position encoding is low-current drain. • Capacitive encoding is a way to realize low-power consumption without giving up resolution or accuracy, even at relatively low speeds.
