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 ...

ROHM recently announced the development of the BU6904GF/NUX and BU6906GF/NUX fan motor drivers with built-in Hall element ideal for driving cooling fans in notebook PCs, tablets, and gaming systems.

This file type includes high-resolution graphics and schematics when applicable. In the seemingly endless quest for higher motor performance and improved system cost efficiencies, motor manufacturers ...

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 ...

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 ...

Closed-loop motion designs in aerospace, semiconductor, automotive, military, and medical manufacturing, as well as oil-and-gas exploration and production, require repeatable and reliable measurement ...

In the first installment of this series, "Calculating a practical hotspot safety margin", we discussed how two-parameter thermal models assume that the entire motor, including windings, exhibits one ...
