A LIMIT to the power output of most rotating electrical machines is set by magnetic saturation in the teeth of the punchings employed. Designers of these machines have, however, never had data ...

In order to drive motors at high efficiency, it is necessary to consider a variety of factors, including construction of the motor, components, and drive method. This series will introduce some basic ...

The D36X50R MAGnum magnetic hammer drilling system uses rapidly rotating magnets of alternating polarity within the carriage assembly to create a high frequency percussive action that fractures and ...

A FULL discussion is given in this book of the practical theory of the induction motor and of several of the main types of alternating current motors. The author also gives a historical account of the ...
