How Energy Converted From One Form to Another
How Energy Converted From One Form to Another

In this article, we are going to see energy conversion between thermal, electrical and mechanical

It is possible to convert the energy from one of these forms to any one of remaining forms.

Electrical To Thermal Energy Conversion

An electric energy can be applied as an input to a water heater or a furnace in order to convert it into a thermal energy.

The thermal energy will be the output energy, which will be utilized to raise the temperature of the water or to heat the substance kept inside the furnace.

Room’s heaters, iron filaments are some other application in which the electrical to thermal energy conversion is observed.

Electrical To Mechanical Energy Conversion

The meaning of the words electromechanical energy conversion is the conversion of electrical energy into mechanical energy or mechanical energy to electrical energy.

The conversion of electrical energy to mechanical energy is achieved by using some type of a motor. An electric energy is applied to a motor. The motor rotates and converts electrical energy to mechanical energy, which is available at the shaft as shown in fig.

Depending on the type of source of electrical energy, the motor can be an AC motor or a DC motor.

The motors continuously convert the electrical energy into mechanical energy. But some other devices are used to convert electrical energy to mechanical energy in an intermittent manner. The examples of such devices are solenoids, relays, electromagnets etc.

Some of the applications in which the electrical to mechanical energy conversion is used are.

  1. Cranes
  2. Water pumps
  3. Lift
  4. Electric trains
  5. Battery driven vehicles.

Mechanical to Electrical Energy Conversion

Electric generator

An electric generator converts the electrical generator converts the mechanical energy applied at its input to an electrical energy.

A prime mover machine is required to be used to rotate the generator mechanically.

At the output of the generator, we get electrical energy, which can be applied to the electrical loads.

The generators can be AC generators or DC generator. The AC generator is called as alternators.

Thermal to Electrical Energy Conversion

The best example of thermal to mechanical and then electrical energy conversion is the boiler-steam-generator system like explained below.

The boiler uses coal to produce heat. This heat produces steam. The steam pressure is used to rotate a turbine.

The turbine will rotate the generator and the electrical energy is obtained at the generator output

Thermal to Mechanical Energy Conversion

A diesel engine is an example of thermal to mechanical energy conversion.

The diesel engine operates on the heat produced by the burning of diesel, thus converting heat into a mechanical motion.
