Since DC machines require more attention than their AC counterparts ... If you detect threading soon enough, you can machine the commutator in place to restore the finish. Too little brush spring ...

By contrast, when a commutator is used in a generator application, it acts like a rectifier to convert the generated AC voltage of the machine into DC voltage. Brushes, which are usually made of ...

John Bird, Commutator Supervisor at Sulzer’s Birmingham Service Centre looks at the processes involved in delivering a fully refurbished commutator. The first, and possibly most important step ...

I am trying to reduce the electrical noise from a 12V 5A brushed dc motor, driven via a pulse width modulator ... Part of me is a bit itchy about putting caps straight across the commutator as I was ...

A linear dc motor, like a rotating dc motor ... transfers power into the conductors located under the slider through commutator segments. Two of three phases are energized at any one time.

RECENT advances in the application of single-phase alternating currents to electric traction have given rise to a large volume of literature dealing chiefly with the motors employed. The ...

THOSE who are acquainted with Dr. Goldschmidt's writings will open this book with the expectation of finding a very intricate subject treated in clear and simple style, and this expectation will ...

1. Simple in construction, a general-purpose dc brush motor includes an armature or rotor, a commutator, brushes, an axle, and a field magnet. Naturally, a battery or power supply is required.
