Electricity Generator

Electricity Generator: Converts mechanical energy to electrical energy

Importance: The majority of the electrical energy used by the human race is created by generators

Parts of the Generator

Rotor: The part of the generator that rotates or spinsStator: The stationary part of the generator

How does it generate electricity?

1) Create coils out of copper wire and place them around the magnet in a circle

Page 6: The Generator. Electricity Generator Energy: The ability to do work Two Examples: Mechanical Energy: Energy that comes from the motion of an object Electrical

How does it generate electricity?

1) Create coils out of copper wire and place them around the magnet in a circle

2) Place a magnet such that it can be spun around the coils

(Alternately the coils can spin inside the magnet)

How does it generate electricity?

1) Create coils out of copper wire and place them around the magnet in a circle

2) Place a magnet such that it can be spun around the coils

(Alternately the coils can spin inside the magnet)3) Find a way to create the mechanical needed to spin the center magnets

2) Place a magnet such that it can be spun around the coils

(Alternately the coils can spin inside the magnet)3) Find a way to create the mechanical needed to spin the center magnets4) Once the center spins it causes the copper’s electrons to flow in the copper wires = electrical energy

Two Types of Generators

1) Dynamos: Create direct current which is current that travels in one direction only

2) Alternators: generate alternating currents (travel in one direction then the other )

Generators and Motors

Electrical Generators and Electrical Motors both contain the same parts.

- Forcing the rotor of an electric motor to spin it can cause it to generate an electrical current

- Adding electric power to an electrical generator will cause the rotor to spin.
