Difference Between Motor and Generator

1. Definition

Motor

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

Generator

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

2. Rule

Motor

• Electric motor follows Fleming’s left-hand rule.

Generator

• Electric generator follows Fleming’s right-hand rule.

3. Principle

Motor

• 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.

Generator

• The working principle of generator is based on electromagnetic induction.

4. Driving force for shaft

Motor

• The shaft of an electric motor is driven by a magnetic force which is developed between the armature and field.

Generator

• The shaft of an electric generator is connected to the rotor which is driven by a mechanical force.

5. Current Usage

Motor

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

Generator

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

Example

• Ceiling fans, cars, etc. are all examples of motor.

• In power stations, generator is used to generate electricity.

hope it helps you

thanks

Answer 2

Answer:

• Electric motor converts electric energy into mechanical energy while an electric generator converts mechanical energy into electrical energy.

• Electric motor gives out back emf to the circuit, electric generator gives emf to the load connected.

• Electric motor works on the principle of force on a current carrying wire, electrical generator works on the principle of electromagnetic induction.

Electric motor

Example - Motors are used in Electric car

Electric generator

Example - Generators are used in power stations, house etc.
