Brushless and brushed motors, as two common types of DC motors, exhibit significant differences in structure, working ...

Sizing a DC motor to accurately meet a set of requirements can be a thankless task. Sizing a DC motor to accurately meet a set of requirements can be a thankless task. Having to choose between ...

DC motors may not be the wave of the future, but they certainly have a secure place in today’s workplace (see DC Isn’t Dead). Therefore, it’s worthwhile for electrical professionals to take a look at ...

In the 1830s, a self-educated blacksmith invented a brush and commutator dc motor. Thomas Davenport first witnessed an electromagnet in action separating iron ore in the mining process. He bought one ...

Scientific American is the authority on science and technology for a general audience, with coverage that explains how research changes our understanding of the world and shapes our lives. First ...

Several industries – including mining, steel, rail and power generation – rely on large motors equipped with commutators to produce the power required by their applications. However, without precision ...

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 ...

DC machines can be classified as self-excited, separately excited, permanent magnet (PM), and brushless. Self-excited machines can be further classified as shunt, series, and compound. Compound ...

Sponsored by Texas Instruments: With the driver ICs available today, brushed DC motor control is a snap to integrate in building-, home-, and industrial-automation applications. Motors are everywhere, ...
