The MTD6501D is a three-phase brushless DC sinusoidal sensorless fan motor driver in an MSOP package. This devices features 180º sinusiodal drive, high torque output, and silent drive. It is intended ...

For the PDF version of this article, including diagrams, click here. Laptop/notebook PC cooling fans demand low noise and high efficiency. The latter is particularly important as notebook designers ...

Brushless-dc motors are taking center stage in medical-equipment design because they last twice as long a competing technologies. • Sensorless brushless-dc-drives have evolved to a point where they ...

Motors are everywhere—from air conditioners and vacuum cleaners to power tools and industrial equipment. As globalisation and ...

[Davide Gironi] shows us how to implement a sensorless brushless DC motor controller (sensorless BLDC) using an ATmega8 microcontroller. In order to control a BLDC motor you need to know its ...

There are trade-offs between brushed and brushless motors, considering factors such as maintenance, efficiency and upfront costs, Control Design writes. For automation engineers, the evolving ...

One of the perennial challenges of building robots is minimizing the size and weight of drive systems while preserving power. One established way to do this, at least on robots with joints, is to fit ...

In the world of power tools, brushless motors are all the rage. While the technology isn't exactly new, it has gained traction in recent years due to some high-profile releases by Makita, Milwaukee, ...

Does your "winter project" need some cooling-fan help? As in one that doesn't eat up a lot of juice from the battery, has an ultra-efficient design to cool your Mopar down, and can last a long time?
