Motor and Generator Differences in Physics Import Concepts Must to Know
Question. Difference Between Motor and Generator.
Answer:
Differentiating Property | Motor | Generator |
Definition | Electric motors convert electrical energy into mechanical energy. | Generators convert mechanical energy into electrical energy. |
Law | Fleming՚s left-hand rule is followed to know the direction of motion. | Fleming՚s right-hand rule is followed to know the direction of produced electricity. |
Source of energy | Power grids, electrical supply. | Steam turbines, water turbines, internal combustion engines. |
Current | In motors, the current has to supply to armature windings. | In generators armature windings produce current. |
EMF | The electric motor gives outback emf to the circuit. | The generator gives emf to the load connected. |
Types | DC Brushed Motors, DC Brushless Motors, AC Brushless Motors, Direct Drive, Linear Motors, Servo Motors, Stepper Motors. | Three main types of generators: portable, inverter, and standby. |
Principle | The working principle of a motor is based on the current-carrying conductor that experiences a force when it is kept in the magnetic field. | The working principle of generator is based on electromagnetic induction. |
Driving force for shaft | The shaft of an electric motor is driven by a magnetic force which is developed between the armature and field. | The shaft of an electric generator is connected to the rotor which is driven by a mechanical force. |
Use | Automobiles, elevators, fans, pumps, etc. | In power supply chains in industries, testing purposes in the laboratory, general lighting, powering of batteries, etc. |
Example | Ceiling fans, cars, etc. are all examples of motor. | In power stations, generator is used to generate electricity. |
