How do electric motors and generator work?

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?

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.
