The magnetic energy that is used to run a motor over time does not require an outside energy source to generate electricity like the sun or water. It is running purely on the magnet arrangement. However, over time, the magnets can lose their magnetism, so they will have to be replaced at some point to continue to generate electricity.

What is an electric generator?
An electric generator is a device that converts a form of energy into electricity. There are many different types of electricity generators. Most of world electricity generation is from generators that are based on scientist Michael Faraday’s discovery in 1831 that moving a magnet inside a coil of wire makes (induces) an electric current to flow in the wire. He made the first electricity generator called a Faraday disk, which operates on this relationship between magnetism and electricity and which led to the design of the electromagnetic generators that we use today.
