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 ...

To control system operation, motors require a current measurement, which can be achieved using shunt resistors that provide a simple and cost-effective solution. Motors are used in countless consumer ...

The DC series motor has some desirable properties, but it can become quite dangerous to use if proper safety precautions are ...

The first type of motor built is still in widespread use In the late 1800s, several inventors built the first working motors, which used direct current (DC) power. After the invention of the induction ...

THE first edition of this work appeared in 1904. Since then remarkable advances have been made in electrical engineering. A foremost place in this progress must be given to electric motors, and more ...
