Tachometers directly report angular speed. Some are simple processors that merely digest output from an external sensor or encoder; others are integrated units that combine an encoder or sensor and a ...

Basic motion designs compete with those produced in emerging markets, but automation reigns where value trumps cost. Key to extracting superior production from such sophisticated machinery is the ...

Alignment of optical encoder commutation signals to a Brushless DC (BLDC) motor could be thought of as being comparable to timing the distributor on a car engine. The distributor tells the spark plugs ...

In a speed controller, the motor’s speed (or velocity) is being controlled. There is an element that detects speed, whether it be a tachometer or some sort of encoder. This monitoring element provides ...

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 ...
