This paper discusses why appliance designers should consider Hall-effect sensor integrated circuits (ICs) for motor control. This document covers several key design characteristics that improve motor ...
Bipolar Hall-effect sensors are used in BLDC motors to detect the position of the rotating magnet. In this example, an eight-pole motor with a three-phase winding uses three bipolar latching ...

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 ...
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 ...
