alleryWhat energy conversion does an electric motor perform?
AMechanical to electrical
BChemical to electrical
CElectrical to heat
DElectrical to mechanical
Answer & Solution
Correct answer: D. Electrical to mechanical
1. An electric motor converts input electrical energy into rotational mechanical energy.
2. A current through the armature in a magnetic field produces a torque.
3. The torque turns the rotor, driving a mechanical load.
4. So motors convert electrical energy to mechanical energy.
5. The opposite conversion is done by an electric generator.
