Generator or dynamo is a device, which produces electric current by the process of electromagnetic induction.
Dynamos and Generators convert mechanical rotation into electric power. Dynamo - a device that makes direct current electric power using electromagnetism. ... Generator - normally this term is used to describe an alternator which creates AC power using electromagnetism.Electric generator, also called dynamo, any machine that converts mechanical energy to electricity for transmission and distribution over power lines to domestic, commercial, and industrial customers. Generators also produce the electrical power required for automobiles, aircraft, ships, and trains.
A dynamo is an electrical generator that creates direct current using a commutator. ... It is basically a DC generator, i.e. an electrical machine which converts mechanical power into direct current electrical power.
An alternator is a device that generates AC power from the rotation of an axle (mechanical energy). They are a bit similar to dynamos, but differ in the fact that they make AC power, whereas dynamo's generate DC power. In addition, they also tend to be more efficient.Dynamos are divided into two general lands: direct current (D. C.) and alternating-current dynamos (A. C.) or simply alternators.
AC and DC generators both use electromagnetic induction to generate electricity. However, the process they use is different. An AC generator creates an alternating current that periodically reverses direction. But in a DC generator, a direct current flows in one direction.
