The broad world of DC motors is divided into two basic categories: brushed and brushless. The brushed motor has been around “forever” and while billions of such motors in use prove it can work well, ...

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 ...

A family of brush and brushless dc vibration motors are aimed at a wide range of applications. The 10-mm diameter coin-shaped devices include the brushless dc vibration motors: the LBV10L at 3.4 mm (0 ...

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, ...

Klaus Neuenhueskes looks at brushless DC motor control in cars and discovers that H-bridge controllers have specific advantages for designers. According to a recent report by research firm IHS, around ...

What is a brushless ESC, really? Well, generally, it’s usually a microcontroller with a whole lot of power transistors hanging off it to drive three phases of brushless motor coils. [Frank Zhao] ...
