An electric motor does this
electric energy to mechanical energy
An electric motor converts electric energy to mechanical energy while a generator converts mechanical energy to electric energy.
That's called an electric motor.
Conversion of electrical energy into mechanical energy
motor
An electric motor is an electromechanical energy conversion devicewhereas an electric drive is that which involves control of speed or position of the motor.
Electric motor is an example of conversion of energy. Electric generator is another example.
The motor energy transfer refers to conversion of electrical current to magnetic, kinetic, heat and sound energy. The energy that leads to the rotation of the motorÕs axis is referred to as kinetic.
What motors do is to convert one type of energy into another type of energy. And as that conversion is never 100% efficient, some of the energy is turned into heat, which heats up the motor.

Energy conversion takes place when one form of energy is converted to another form. An example would a turbine, which converts heat energy to mechanical energy, or a generator which converts mechanical energy to electrical energy, or an electric motor which converts electrical energy to mechanical energy. In all conversion processes energy is lost (i.e. it is converted to heat at a low temperature). The useful power output of a machine is always less than the power input, by a ratio called the efficiency, usually expressed as a percentage. Typical efficiency for an electric motor is 95%, for a car engine 25%.
