A dc generator is an electrical machine which converts mechanical energy into direct current electricity. This energy conversion is based on the principle of production of dynamically induced emf. Learn everything related to dc generator from this page.
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
Please go through the construction of dc generator before reading this article about different types of dc generator. A DC generator requires MMF to establish flux in its magnetic circuit.
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
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
Speed control of dc motor is achieved using different methods. There are three types of dc motors. For each of them, there are different methods of speed control. Each of
Insulation Resistance or IR Test is carried out by maintenance engineers to ensure the healthiness of the overall insulation system of electrical equipment. It reflects the presence or absence of
Electric Motors need maintenance regularly in order to avoid failure and prolong their lifespan. Generally, motors and motor parts should be maintained and tested at least every 6 months. Then
DC generator characteristics are the relations between excitation, terminal voltage and load exhibited graphically by means of curves. These characteristics of dc generators are very important in the design and operation of dc generators. This article describes the
Compensating Windings and Interpoles are one of the important step taken to minimize the undesirable effect of armature reaction in dc machines. Armature reaction causes many undesirable effects on a
In a separately excited dc generator, the field coils are energized from an independent source. The disadvantage of a separately excited DC generator is the same that we require an external
