I am trying to reduce the electrical noise from a 12V 5A brushed dc motor, driven via a pulse width modulator. Much as I would have fun trying various configurations, I would also like to get the ...

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 ...

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 ...

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 ...

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, ...

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 ...
