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, ...

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, ...

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 ...

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 ...

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 ...

The LO-COG Series 8690 of 26-mm brush-commutated DC motors are available in 1.798'', 1.923'' and 2.173'' lengths and provide continuous torque output up to 3.17 oz.-in., peak torque up to 20 oz.-in., ...
