(SCI) Generators and Motors

• Electromagnetism is the principle that explains how electric motors work.
• An electric generator is a device that converts mechanical movement into electricity.
• An electric motor is a device that converts electricity into mechanical movement.
• Electric and magnetic forces are required for generators and electric motors to work.
• A coiled wire in an electric motor would rotate and change electrical into mechanical energy, if there is a repulsion and attraction of magnetic poles.
• A generator is a device that produces an electric current when a coil of wire us wrapped around an iron core and rotated near a magnet.
• Michael Faraday discovered electromagnetic induction,
• A commutator changes AC to DC voltage within the armature winding of a generator.
• The basic parts of an electric motor is the commutator, stator, and rotor (CSR).
