Difference between motor and generator

The generator and motor are such a device whose function is just the opposite of each other. One is used to generate electricity and other uses of electricity. In this article, we will learn about the difference between motor and generator to better understand this topic.

Electric motor:
  • An electric motor generates energy from electrical energy
  • Electricity is required for its operation
  • In while uses an electric motor, electrical energy is in the input form
  • Flemings left-hand rule is followed to know the direction of motion
  • Source of energy is power grids, electrical supply
  • The motor is used in automobiles, elevators, fans, pumps, etc
  • The maintenance of the electric motor is less as compared to the generator
Generator:
  • The electrical generator generates electrical energy from mechanical energy.
  • Generator generate electricity
  • In the generator, electrical energy is in the output from
  • Flemings right-hand rule is followed to know the direction of produced electricity
  • Source of energy are steam turbines, internal combustion engines.
  • The generator is used in power supply chains in industries, testing purpose in the laboratory general lighting, power of batteries, etc
  • The maintenance of the generator is more as compared to the motor
The main key difference between generator and electric motor are given below:
  • The generator is a device which converts mechanical energy into electrical energy whereas the motor is a device which converts electrical energy into mechanical energy.
  • The generator used to generate electricity while the motor used to generate mechanical power.
  • In generator, the current is produced in the armature winding whereas in the motor the current is utilized in the armature winding to produce mechanical force. The armature can be on rotor or stator.
  • In generator, the direction of the current induced is determined by the use of Flemings right-hand rule while in motor the direction of force produced is determined by the use of the flaming left-hand rule.
  • The example of the motor is an electric car or bike where the electric current is supplied to the machine or device. and it gets converted into mechanical motion and as result the car or bike device, and it gets converted into mechanical motion and as result turbine is used as a device which converts the mechanical energy of the force of water falling from the dam to generate electric energy.
  • In generator the shaft is driven by the mechanical power,  in motor, the shaft is driven by the mechanical force produced by the electricity.
  • The maintenance of the generator is more compared with the motor.
