A generator converts mechanical energy into electrical energy, while a motor does the opposite – it converts electrical energy into mechanical energy. Both devices work because of electromagnetic induction, which is when a voltage is induced by a changing magnetic field.
How does an electric generator work?
Electric generators work on the principle of electromagnetic induction. A conductor coil (a copper coil tightly wound onto a metal core) is rotated rapidly between the poles of a horseshoe type magnet. … The magnetic field will interfere with the electrons in the conductor to induce a flow of electric current inside it.
How are electric motors and electric generators similar?
With a chuckle I explained that I just did, and that an Induction Motor and a Generator are essentially the same device. … While an electric motor converts electricity into mechanical work, a generator converts mechanical work into electricity.

What is the price of electric generator?
The price of a generator with a power rating between 100 and 200 KVA varies from Rs 5.4 lakh to Rs 10.7 lakh with specifications that include: Diesel powered. Available in single phase and three phase power generation. Soundproof.
Can electric motors be used as generators?
You can use just about any motor to generate electric current, if it is wired correctly and you follow specific rules for its use. Modern AC induction motors are quite simple to wire as alternating current generators, and most will begin generating electricity the first time you use them.
What are examples of electric motors give at least 2 examples?
Electric motors :
- Ceiling fan – Induction motor.
- Air conditioner – contains motor in compressor and blower fan.
- Computer CPU and laptop – Brushless DC motor(Cooling fan)
- Table fan, exhaust fan – Induction motor.
- Grinder – Induction motor.
What kinds of devices are powered by electric generators?
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.
What is the cheapest way to generate electricity?
The consensus of recent major global studies of generation costs is that wind and solar power are the lowest-cost sources of electricity available today.

Which generator is more expensive?
In this regard, diesel generators score high. While they are a considerably more expensive alternative in comparison to natural gas generators, since the price of diesel is more than that of gas, diesel has a higher energy density.
What size generator do I need to run a 30 hp motor?
Rule of Thumb
|Electric Motor Size||Minimum Generator Req’d (KVA) by Starting Method|
|HP||KW||S.D to KVA Size (Note 2)|
How big a generator do I need to run a house?
You can run the most critical household equipment with a generator rated at 5,000 to 7,500 watts. These include things like a well pump, refrigerator and freezer, and lighting circuits. A generator with around 7500 running watts can run all these appliances at once. For RV, a 3000 – 4000-watt generator would be ideal.
