Special hardware can overcome software latency that may otherwise negate precise motion control. Precision motion control is virtually never an end in itself. Rather, it ties position to other events ...

• 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.

Quadrature encoders have many uses in position-sensing applications. This implementation uses a Xilinx complex programmable logic device (CPLD) to count the pulses from the encoder and determine the ...

Besides having standard data channels, the RCM and RCH series of incremental rotary encoders are able to develop output signals for commutation of brushless motors. The optically derived commutation ...

Encoders are integral parts of motor-control systems that sense mechanical motion, then generate digital signals in response to that motion. The trend today is to create smaller mechanical and ...
