This Design Idea combines a simple ISA-bus-resident interface circuit; a garden-variety PC; a high-resolution optical shaft encoder; and a PWM-controlled, 0.05-hp, brushed, permanent-magnet dc motor ...
Available in one-, two-, three-, and four-axis configurations, the Magellan PC/104 motion-controller card features trajectory generation, servo-loop closure, quadrature-signal input, ...
Rotary quadrature encoders often are used to command digital potentiometers or digital controllers, and quadrature decoding is typically performed in a programmable device (like an FPGA or ...
