  1. Generators Sarah Sargent

  2. Generator • A Generator is a Group of devices used to convert mechanical energy into electrical energy, or electrical energy into mechanical energy. • This can be done by spinning an armature (one of the electrical components of a motor that contains conductors) through a magnetic field

  3. How do they work? A spinning copper coil located between two magnets can create a steady flow of electrons. Forcing these electrons or electric charges to move through an external circuit that connects to anything that needs power produces the energy to make it work. The relation between magnets and electrons shows how a generator functions. By passing electrons through electrical wires, conduction of electricity happens when forced by the magnetic fields produced when mechanical energy converts into electrical energy.

  4. Generators are based on the Principle of electromagnetic induction which was introduced by Michael faraday in 1831. Faraday’s Disk

  5. Parts of a Generator

  6. Gas and wind powered Generators Gas Powered Generators • Home appliances such as refrigerators, air-conditioners and furnaces can run on gas-powered electricity when there are power outages. Home generators provide temporary power by the introduction of electricity through temporary connections of the appliances to the generator. If needed, connecting a generator to a home's electrical system permanently can automatically trigger electricity during blackouts. Wind Powered Generators • The propellers or blades around a rotor turn when the wind blows against them, producing energy. This energy passes from the rotor to the main shaft, then spins the generator to create electricity. A tower is approximately 100 feet in height and wind turbines can produce electricity for a single building or home as well as distribute electricity through power grids.

  7. AC Generators • When a coil of wire is moved through a magnetic field, the electrons in the wire are forced to move creating a current flow. The north and south poles of the magnet will cause the current to flow in opposite directions in any wire they pass, causing an "alternating Current."

  8. DC Generators • One type of generator, called direct current generator (DC), spins the conductors in a still magnetic field. This magnetic field is rotated by the alternator and is cut by the stationary conductors.

  9. The two types of Generators There are two types of generators portable and standby. standby generators are larger that portable generators Portable generators provide temporary power for areas such as camping sites or construction sites. They can provide enough power for smaller appliances by using gasoline as fuel.

  10. The importance of Generators • Generators can provide electricity during power interruptions. They can prevent companies from losing productivity during a power outage. • They provide backup power in case the main source of electricity switches off during a power outage
