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 quest for energy-efficient designs has made capacitive position encoders a hot topic. • The new mantra of position encoding is low-current drain. • Capacitive encoding is a way to realize ...

That level of resolution is ideal for commutation, high-speed motor control, position/velocity control, and replacement of potentiometers and optical encoders. It’s a low-power 3.3-V (or 5-V) device, ...

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 ...

This application report offers a solution for obtaining high-resolution position with sin/cos encoders using the Texas Instrument (TI) TMS320F240 digital signal processor (DSP) controller. This is ...

For engineers seeking a motor scaled down in size but not power, QuickSilver Controls has extended its Mosolver (portmanteau of “motor” and “resolver”) servo motion actuator into a NEMA 17 frame ...

Engineers using an incremental encoder for the first time often have a misunderstanding about what types of signals are provided by an encoder and how to interface an encoder to their application.
