2. ELECTROMECHANICALCONVERSION PRINCIPLES
PROJECT FOR STUDENT• Collect information on “MOTOR”, “RESISTANCE” and “LED”• Bring following material : 1) Small Motor (Any RPM) 2) Any Resistance 3) One RED LED
In electromechanicalsystems, energy isstored in magneticand electric fields.
An Electro-mechanical energy is converted electrical energy into mechanical energy ORmechanical energy into electrical energy.
Electromechanical energy conversiondevices:-1) Small motion like telephone receivers,microphone, Load-speakers etc2) Consist of Force or Torque producingdevices like Electro magnets, relays,moving coil instruments etc3) Continuous energy conversion likemotor and generators.
The energy storagecapacity of the magnetic field is much greater (about 25,000 times) than electric field.
According to Principal of energy conversion, energy can neither becreated nor destroyed, it can be converted from one form to another form.
