Concept explainers

Speed control of motor

Speed control by DC motor-speed controller is required to realize variable speed drive. Whenever a motor drives a particular load, it is called drive, and variable speed drive refers to a load requiring variable speed. All this is obtained by a DC motor speed controller.

3.12 A carbon brush used to conduct current from the commutator of a DC generator has a length of 4 in. It must conduct a current of 400 A with a voltage drop not exceeding 2 V. Determine the cross-sectional area of this carbon brush. 3.13 Early DC machines use brass brushes instead of carbon brushes. The com- mutator bars do not last very long since brass is a rather hard metal. If a brass brush of the dimensions determined in problem 3.12 is used instead to conduct the same current, determine the voltage drop.
According to Coulomb's law: Select your answer. The product of two charges produces an inversely proportionate force. The force of two-point charges is proportional to the square of their distance. The point charge cannot be stationary (at rest). The two-point charges must be along the line joining them.
