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 ...

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 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 ...

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 ...

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, ...

The development of moving-coil or coreless motors dates back to the middle 1930s. The development of moving-coil or coreless motors dates back to the middle 1930s. But it wasn't until the early 1960s ...
