Difference Between Motor and Generator

The Electric Motor and Generator are differentiated on various factors like the main principle of working or function of the motor and generator. Consumption or production of electricity, its driven element, the existence of the current in the winding. Fleming’s rule followed by the motor and generator.

The Difference Between the Motor and the Generator are explained below in the tabulated form.

BASISMOTORGENERATOR
FunctionThe Motor converts Electrical energy into Mechanical EnergyGenerator converts Mechanical energy to Electrical energy.

Electricity It uses electricity.It generates electricity
Driven element The Shaft of the motor is driven by the magnetic force developed between armature and field.The Shaft is attached to the rotor and is driven by mechanical force.
CurrentIn a motor the current is to be supplied to the armature windings.In the generator current is produced in the armature windings.
Rule FollowedMotor follows Fleming’s Left hand rule.Generator follows Fleming’s Right hand rule.
Example An electric car or bike is an example of electric motor.Energy in the form of electricity is generated at the power stations.

 

The motor and the generator are almost similar from the construction point of view, as both have stator and rotor. The main difference between the two is that the Motor is an electric device which converts electrical energy into mechanical energy. The generator is vice versa of that motor. It converts mechanical energy into electrical energy.

The Difference between Motor and Generator are as follows:-.

  • The Motor converts electric energy into mechanical energy, whereas generator does the opposite.
  • Electricity is used in the motor, but the generator produces the electricity.
  • The Shaft of the motor is driven by the magnetic force developed between armature and field windings whereas, in the case of the Generator the Shaft is attached to the rotor and is driven by mechanical force.
  • The current is to be supplied to the armature windings in case of a Motor, and in Generator, current is produced in the armature windings.
  • Motor follows Fleming’s Left hand rule while Generator follows Fleming’s Right hand rule.
  • The example of Motor is an electric car or bike where electric current is supplied to the machine or device, and it gets converted into mechanical motion and, as a result, the car or bike moves. The example of Generator is that in power stations the turbine is used as a device which converts mechanical energy of force of water falling from the dam to generate electric energy.
