Motor control circuits in appliances including refrigerators, washing machines and air conditioners, need to operate more efficiently, reliably and safely while meeting cost requirements. With energy ...

Recently, [Solder Hub] put together a brief video that demonstrates the basics of a Hall Effect sensor — in this case, one salvaged from an old CPU fan. Two LEDs, a 100 ohm resistor, and a 3.7 volt ...

Hall effect sensors are everywhere right now. Keyboards, game controllers, and DIY kits use them for more precise inputs. But with any newly popular device, it can be easy to immediately jump onto the ...

Sensing current, especially in higher-voltage settings, is often a challenge. It’s generally more difficult than voltage sensing, as it is usually “invasive” and requires “breaking” into the ...

As previously mentioned, the feedback sensors include position sensors to track the rotor’s location, current sensors to measure the motor phase currents, voltage sensors to monitor the DC bus voltage ...

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds deceptively simple. There’s a metal plate with current flowing across it in one ...
