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- ...

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, ...

Preventive maintenance maximizes uptime while controlling costs. Maintenance crews strive to reduce maintenance costs and manage their workloads more effectively. Since DC machines require more ...

We may receive a commission on purchases made from links. Shopping for tools can either be a straightforward process or one that requires a little research. Buying a new Philips screwdriver takes ...

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 ...

NASA considers several qualities of motor-brush materials when determining suitability for a given mission. Among the most important are the wear rate and the cohesiveness of the debris. Engineers ...

A few characteristics of dc motors maintain linear relationships that allow for very predictable operation. First, if enough voltage is applied across the terminals of a dc motor, the output shaft ...

The first type of motor built is still in widespread use In the late 1800s, several inventors built the first working motors, which used direct current (DC) power. After the invention of the induction ...
