When choosing a modern power tool, there are many factors to consider before buying. The power source, brand, and price are arguably the most important, but there's one more key distinction to make: ...

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, ...

With the increasing use of variable-frequency drives (VFDs), there is increased generation of electrical currents on shaft motors, causing electrical damage to bearings. Manufacturers and end users ...

Running a brushed motor in muddy or dusty environments takes a toll on controllers, with both heavy back EMF and high stall currents. This explains one of the challenge in Europe’s Hacky Racer series, ...

This article explains how to create a brushed DC motor programmable speed regulator that is low-noise, high-performance, and affordable. The regulator is not affected by changes in temperature, ...

The motor and motor control markets are thriving in a number of areas, particularly medical and robotic applications. Also, there is a rich demand for small, efficient, high- and low-torque, and high- ...

Permanent magnet direct current (dc) motors convert electrical energy into mechanical energy through the interaction of two magnetic fields. One field is produced by a permanent magnet assembly; the ...

Why there’s a continuing role for brushed DC motors. The multitude of small-motor applications for autos. How motor drivers can enhance performance and connectivity. It’s easy to assume that brushed ...

Design engineers know that both brush DC and brushless DC (BLDC) motors can operate as generators, but many tend to avoid running brushed DC motors in generating mode because they believe it is ...

In the world of motion technology, few components have proven as enduring and versatile as the brushed DC motor. Known for its simplicity, reliability, and cost-effectiveness, this classic motor ...

A motor — or a generator — requires some normal magnets and some electromagnets. The usual arrangement is to have a brushed commutator that both powers the electromagnets and switches their polarity ...
