A quadrature encoder provides a way to let hardware read movement (and direction) of a shaft, and they can be simple, effective, and inexpensive devices. But [Paulo Marques] observed that when it ...

The counter project was created to read one or two digital or analog sensors and display the running total on an organic LED display. The speed of an attached DC motor can be controlled by the counter ...

LSI Computer Systems (LSI/CSI) has created a family of 63 tap (6bit) digital potentiometers for direct connection to quadrature decoders, push buttons, GPIOs or SPI serial controls. Debounce circuits ...

This Design Idea utilizes an optical computer mouse's sensor for measuring rotation of a disk which can be mechanically connected to any sort of rotating apparatus. One feature is to allow adjustment ...

To attain accurate positioning, a servo system requires a feedback signal to close its feedback loop. Instruments that typically supply the feedback signal include optical encoders, resolvers, and ...

Encoders are the most widely used feedback devices for electric motor control, capable of delivering precise position and speed feedback for closed-loop performance. With numerous technology options ...

UNTERPREMSTAETTEN, Austria--(BUSINESS WIRE)--The new AS5601 contactless rotary position sensor from ams AG (SIX: AMS), a leading provider of high performance analog ICs and sensors, gives designers an ...

New to the Posirot family of incremental magnetic ring encoders is the PMIR7 Series. The encoders are available in three sizes to accommodate 27, 35, and 50-mm shaft sizes and yield up to 184,320 ...

Constant-speed ac-induction motors don't really hold a constant speed. It's just that their speed varies least from no load to full load of all ac-induction motors. Other induction-motor types don't ...

This article is part of the Ideas for Design Series: Vol. 3, No. 8. In many applications, accurately sensing the position of an electrically controlled mechanical device such as a motor is critical.
