Motor commutator noise – help me? 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, ...

ServoTek Products Inc. announced the successful application of its TachSyn Series brushless DC tachometer/commutator within industrial motor speed monitoring applications.

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 t… ...

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 ...

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 ...

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 ...
