An electrical motor is a device that turns electrical energy into mechanical energy.
Dynamo.Such a device is known as a generator, sometimes also as a dynamo.
Mechanical energy

The simplest example is an electric generator.
One example is an electric motor, which turns electrical energy into kinetic energy.
fan converts electric energy into magnetic and further mechanical energy
The generator can't create energy out of nothingness. It's converting mechanical energy to electrical energy. That mechanical energy has to come from somewhere ... the steam that turns the turbine, the wind that turns the sail, the falling water than turns the wheel, or the arm of the guy who turns the crank.
The wind turbine converts kinetic energy into wind, which then turns into wind and then mechanical energy. The energy is converted to an electrical generator through a shaft which turns it into electrical energy, or in other words, electricity.
Here are a few examples: Engines (gasoline, diesel, gas turbine) - Convert chemical energy to mechanical energy. Electric motors - Convert electrical energy to mechanical energy. Wind turbines - Convert the kinetic energy of wind into mechanical energy (which is then commonly turned into electrical energy by a generator hooked to the turbine). A light bulb - Turns electrical energy into light and heat. A wood stove - turns chemical energy into heat (and a bit of light) A roller coaster - converts back-and-forth between potential energy (the cars high on a hill) to kinetic energy (the cars going fast). A solar cell - Turns light into electricity
It turns into mechanical energy-a mass of air is being pushed through the fan so the air molecules are being given kinetic energy (I'm saying mechanical energy includes kinetic energy)
