Purpose of Slip Rings in an Alternator

by

Slip rings are used in rotating electrical assemblies to make a continuous electrical connection between stationary and moving conductors. This enables the stationary power source to transmit electrical power to the rotating component. Basically, a slip ring is a band of electrically conductive material mounted on a shaft. Although insulated from the shaft itself, the … Read more

Brushless Excitation System

by

Brushless Excitation System is a technology for providing the field current to the Synchronous Generator without using Slip Ring and Carbon Brushes. As this method of Excitation i.e. Brushless Excitation System do not use Carbon Brushes, therefore the losses because of contact resistance of carbon brushes is eliminated. Also, in case of initial start up … Read more
