Question

What is the difference between motor and generator PDF?

Answer 1

The main difference between a motor and a generator lies in their function and how they convert energy:

1. Motor:
   

   - Function: A motor converts electrical energy into mechanical energy (motion).
   - Working Principle: When electrical current flows through the motor's windings (coils), it creates a magnetic field that interacts with another magnetic field, causing the motor to rotate and perform mechanical work (e.g., moving a fan blade, driving a conveyor belt).
   - Energy Input: Electrical energy (electricity).
   - Energy Output: Mechanical energy (motion).

1. Generator:
   

   - Function: A generator converts mechanical energy (motion) into electrical energy.
   - Working Principle: When a mechanical force (such as a turbine or hand crank) rotates the generator’s coil in a magnetic field, it induces an electrical current in the coil due to electromagnetic induction. This current is then supplied as electrical power.
   - Energy Input: Mechanical energy (motion).
   - Energy Output: Electrical energy.

In summary, a motor uses electrical energy to produce mechanical motion, while a generator uses mechanical motion to produce electrical energy.
