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 ...

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 ...

Measuring a magnetic field can be very easy with some pretty low tech, or it can be very high tech. It just depends on what kind of measurement you need and how much effort you want to expend. The ...

Diodes is aiming at contactless rotary motion and proximity detection with a 3D Hall-effect magnetic field sensor. Automotive applications are envisaged, include infotainment rotary and push selectors ...

A new range of automotive-qualified current sensors is addressing the growing need for accurate, isolated current measurement ...

Enlisting patent-pending BiCMOS technology, the SNDH series quadrature industrial speed-and-direction sensors take a practical approach to replacing sensor-bearing products with the goal of making ...

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 ...
