Brushless and brushed motors, as two common types of DC motors, exhibit significant differences in structure, working ...

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 ...

Common terms you will hear discussed with DC motors include commutator, brushes, counter electromotive force (EMF), torque, speed regulation, and speed-torque characteristic curves.

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 ...

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 ...

Brushless-dc motors are taking center stage in medical-equipment design because they last twice as long a competing technologies.

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 ...
