1

Definition

An electric motor is a machine that converts electrical energy to mechanical energy.

An electric generator is a machine that converts mechanical energy to electrical energy.`

2

Rule

Electric motor follows Fleming’s left-hand rule.

Electric generator follows Fleming’s right-hand rule.

3

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 the generator is based on electromagnetic induction.

4

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.

5

Current Usage

In a motor, current is supplied to the armature winding.

In a generator, current is produced in the armature winding.

6

Example

Ceiling fans, cars, etc. are all examples of motors.

In power stations, generators are used to generate electricity.

These were the main differences between a motor and a generator that can be asked in the exams. Students aspiring to learn engineering courses are required to get acquainted completely with the concepts of motors and generators.
