What is the difference between AC and DC Generator?

AC Generator DC Generator
AC Generator is a device which converts mechanical energy to AC Electrical Energy DC Generator is a device which converts mechanical energy to DC Electrical Energy

What are the advantages of AC generator over DC generator?

Below are the advantages of AC over DC:

  • AC can be generated at high voltages, but DC cannot be generated at high voltages because sparking starts at the commutator at high voltage, due to which commutator gets damaged.
  • High voltages AC generators are much simpler and cheaper than DC generators of the same range.

How can you convert an AC generator into a DC generator?

Answer Expert Verified The slip rings used in the AC generator can be removed and split rings can be replaced instead. Now, AC generator uses concave magnets, change them and lastly remove the coil and replace it with armature instead. The AC generator will start functioning as a DC generator.

Can a DC motor be converted into a DC generator?

A DC motor converts electrical energy into direct power output while a DC generator converts mechanical energy into direct electric power. A DC motor can be converted into a DC generator while the vice versa is also possible.

What is the working principle of DC generator?

Working Principle of DC Generator. The DC generator working principle is based on Faraday’s laws of electromagnetic induction. When a conductor is located in an unstable magnetic field, an electromotive force gets induced within the conductor. The induced e.m.f magnitude can be measured from the equation of the electromotive force of a generator.

What are the parts of a DC generator?

It mainly consists of three main parts, i.e. Magnetic field system, Armature and Commutator and Brush gear. The other parts of a DC Generator are Magnetic frame and Yoke, Pole Core and Pole Shoes, Field or Exciting coils, Armature Core and Windings, Brushes, End housings, Bearings and Shafts.

How does a DC generator work?

Just as a simple DC electric motor uses direct current (DC) electricity to produce continual, rotary motion, so a simple DC generator produces a steady supply of direct current electricity when it spins around. Like a DC motor, a DC generator uses a commutator.
