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 ...

This file type includes high resolution graphics and schematics when applicable. Rotary encoders track motor shaft movement for myriad pieces of industrial equipment and commercial devices. For ...

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 ...

Position encoders are sensors that, when used in industrial settings, produce critical motor information such as speed and position. The encoder delivers data for display or data that may serve as ...

Torque motors are also called "frameless" motors. They don't have housings, bearings, or feedback devices. In this sense the motor is a kit and meant to be part of the machine structure. Torque motors ...

An interesting trend in industrial motion control has been the replacement of self-contained encoders (rotation sensors with their own housing, bearings and shaft) with modular or “kit” encoders.
