Difference Between Motor and Generator in Detail
An electric motor converts electrical energy into mechanical or kinetic energy, whereas the electric generator transforms the electric energy into mechanical/kinetic energy.
How can we compare and contrast motors and generators? We can do this by comparing them based on energy conversion.
Switching on the button of the fan or the AC button, and getting cool air during summers has the role of motors. Getting electricity supply during power off is possible because of generators.
In this article, we will learn to differentiate electric motor and generator.

The Difference Between Electric Motor and Electric Generator in Tabular Form
Electric Motor
Electric Generator
Motor transform electrical energy into mechanical.
The generator transforms mechanical energy into electrical.
The motor uses electricity. It works on the principle that when a current-carrying conductor is placed in a magnetic field, it experiences a force and rotates.
The word ‘generator’ means to generate something, and an electrical generator produces (generates) electricity.
An electric generator works on the principle of electromagnetic induction or EMI.
We can determine the direction of force with the help of Fleming’s left-hand rule.
For example, when the armature of the motor rotates in a clockwise direction, the direction of the force will be upward. However, if it moves anticlockwise, the force will act downward.
We can determine the direction of the induced current by using Fleming’s right-hand rule.
Since we are getting the output as electricity, we will determine the direction of the current by using Fleming’s right-hand rule.
In electric motors, we use split rings or commutators.
These split rings are called the semicircular rings, they are made by cutting a copper ring into two halves.
In electric generators, we use slip rings; these slip rings are two co-axial copper rings.
The shaft of the motor is driven by the magnetic force generated between the armature and the field.
In electric generators, the shaft is attached to the rotor and is driven by the mechanical force.
Example - An electric car or a bike is an example of an electric motor.
Example - Energy in the form of electricity is generated at power stations. The power stations, in turn, supply this electricity to the buildings in their area.
