This set of DC Generator Problems with Solution focuses on problems based on EMF equation of DC Generator. DC Generator Problem 1 A four-pole generator, having wave-wound armature winding has …
A DC generator is a machine which converts mechanical energy (or power) into electrical energy (or power). The energy conversion is based on the principle of the production of dynamically …
Slip rings are small devices that have a very important role in all types of devices, equipment, and machinery that come in all sizes, from the smallest to the largest …
An amplidyne is an electromechanical amplifier with the characteristics of a rotating machine. It was invented prior to the second world war by Ernst Alexanderson. An amplidyne is a special-purpose …
In this post, we will look at the voltage and power equation of a dc motor and the condition for maximum power in a dc motor. Voltage Equation of a …
This set of DC Generator Problems with Solution focuses on problems based on Types of DC Generator. DC Generator Problem 1 A shunt generator delivers 450 A at 230 V …
The machine which produces 3 phase power from mechanical power is called an alternator or synchronous generator. The working of an alternator is based on the principle that when the flux …
Swinburne’s test is the simplest indirect method of testing dc machines. In this method, the dc machine (generator or motor) is run as a motor at no-load and losses of …
There are several tests that are conducted for testing a dc machine (generator or motor) to judge its performance. The most important performance tests to be conducted on the dc …
