Rotary and linear optical encoders are common in position and motion sensing. Rotary and linear optical encoders are common in position and motion sensing. Here, a disc or plate containing opaque and ...

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 ...

Computer Conversions' Shaft-Tracker resolver-based encoder provides both incremental and true absolute position outputs with a resolution of 4096 counts/turn. A rugged, self-contained, resolver-based ...

The electric motor is the fundamental building block of almost all robotic projects but, without some form of feedback, it lacks the precise positional control required for the task. Small servos from ...

Quadrature-output incremental optical shaft encoders are popular in high-performance, bidirectional rotation-sensing applications. Available with resolution options extending beyond 2000 ...
