Commercial shaft encoders use magnets and Hall-effect sensors, or optical sensors and encoder discs. But these can be quite expensive, so [Hello1024] hacked together an alternative in an afternoon.

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 ...

We always think it is interesting that a regular DC motor and a generator are about the same thing. Sure, each is optimized for its purpose, but inefficiencies aside, you can use electricity to rot… ...

HEIDENHAIN's new PressFit rotary encoders are uniquely designed for feedback and to ease mounting within small motors particularly during automated assembly.

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 ...

POSITAL’s new 22 mm multiturn kit encoders clear the way to exciting new possibilities for miniature motors and drives. While motion feedback devices for small motors have previously been ...

The RENCO R35i and R35iL encoders are ideal for use in brushless DC motors or stepper motor solutions. Their compact size combined with the high level of performance and availability make these ...

The encoder has a high resolution of 4000 CPR, with quadrature, it can reach 16,000 pulses per revolution. A 5-V and 24-V encoder is available, each with a line driver.

Requirements on encoders are becoming more and more demanding. This applies particularly to positioning applications with precision constant-speed control, where increasingly compact housings need to ...
