Current. Too little of it, and you can’t get where you’re going, too much and your hardware’s on fire. In many projects, it’s desirable to know just how much current is being drawn, and even more ...

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 ...

A 22.38 kW, 440-V, 4-pole wave-wound d.c. shunt motor has 840 armature conductors and 140 commutator segments. Its full-load efficiency is 88% and the shunt field current is 1.8 A. If brushes are ...

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 ...

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 ...
