Electric motor and Generator

Cards (24)

  • A generator converts mechanical energy to electrical energy.
  • A generator is a device that converts mechanical energy obtained from an external source into electrical energy as the output.
  • ELECTROMAGNETIC INDUCTION - Faraday discovered that when a conductor moves in a magnetic field, electrical charges could be created and directed to create a flow of current.
  • Stator - the main function of this is to provide magnetic fields where the coil spins.
  • Rotor - in a DC machine includes slotted iron laminations with slots that are stacked to shape a cylindrical armature core.
  • Commutator - works like a a rectifier that changes AC voltages to DC voltage within the armature winding.
  • Brushes - this are in constant contact with the commutator and are attached to the wires leading from the generator.
  • Shaft - this transfers mechanical energy to the generator and turns the coil through the magnetic field.
  • electric motor - anything that changes electricity to motion
  • electric motor - converts electrical energy to mechanical energy
  • Danish physicist HANS CHRISTIAN OERSTED. He showed by experiment that an electric current flowing through a wire could move a magnet.
  • ELECTROMAGNETISM - if you run electricity through a wire, it creates a magnetic field around the wire.
  • Parts of a Generator - stator, rotor, commutator, brushes, and shaft
  • Parts of an Electric Motor - stator, rotor, and commutator
  • A generator is a machine that converts mechanical energy into electrical energy.
  • Generator produces electricity, hence the glowing of LED lights when rotation takes place.
  • the generator is used to produce an electric current from a rotational motion of the CD with handle.
  • generator works on Michael Farraday`s Electromagnetic induction.
  • on a large scale power station like the hydroelectric power plant (San Roque dam) a turbine is used to provide the rotation.
  • an electric motor is a machine that converts electrical energy into mechanical energy
  • the battery supplies the electric current into the coil and it gets converted into motion
  • Hans Christian Oersted discovered that a magnetic field was produced by a flow of electric current.
  • when a battery is connected, the coil creates a magnetic field that interacts with the already existing magnetic field brough by the magnet.
  • the interaction of magnetic fields from the battery and magnet forces the coil to rotate
