Sizing a DC motor to accurately meet a set of requirements can be a thankless task. Having to choose between brush-type or brushless motors can complicate the selection. Even experienced designers may ...

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 ...

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 be ...

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 ...

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 possibility ...
