• Electric Fan


  An air moving machine used to cool with an AC Motor connected to the 60 Hz power source which converts electrical energy to mechanical energy in order to generate a moving air
• Electric Fan


  • It is a power driven machine capable of providing high air flow parallel to the axis of the motor shaft where an axially mounted impeller or fan blade agitates the air
  • The air velocity/delivery of the electric fan is controlled by a mechanical speed selector switch for old models and electronically controlled speed selector switch for new models
  • Timer is also included for fully automatic operations
• Different types of electric fans

  • Desk fan type
  • Wall fan type
  • Ceiling fan or orbit fan type
  • Stand fan type
• Desk fan type


  A fan that is small in size and portable so it can be easily moved around and placed on top of a desk without being unwieldy or taking up too much space
• Wall fan type


  Wall fans are placed on the wall on a mount, can also be found mounted into the flooring or on a work surface, the most common places in which you will find a wall fan are the kitchen, and the bathroom
• Ceiling fan or orbit fan type

  A ceiling fan is a mechanical fan mounted on the ceiling of a room or space, it is usually electrically powered that uses hub-mounted rotating blades to circulate air, nowadays the ceiling fans are usually seen with light fixtures inside them
• Stand fan type


  A stand fan is an electric fan with an adjustable stand that supports it, the metal stand elevates the fan to about two to four feet from the ground
• Whether the electric fans are in different types, all of them operate on the same principle and circuit design
• Oscillating Mechanism


  • Helps the motor fan rotate in back and forth motion, providing larger volumes of air within the room where it is placed
• Electric Motor


  • Provides the rotating magnetic force when it flows in the circuit
  • Consists of two windings, starting winding (auxiliary winding) and running winding (main winding)
• Power Cord


  Connecting point from the fan to the source circuit
• Fan Guard/Grill


  • Can be made of plastic or metal
  • Used to cover the fan blade in order to protect the user from touching the rotating blades of the fan
• Fan Blade


  • Propeller-shaped part made of plastic or metal used to make the air circulate around the room
• Switch


  • Speed control device of the fan
  • Speeds usually include low, medium, and high
• Copper Winding


  A set of copper wire that supplies electricity in the stator and rotor
• Bushing


  An independent plain bearing that is inserted into a housing to provide a bearing surface for rotary applications
• Gearbox Assembly


  Also known as an oscillating mechanism, it helps the motor fan turns from side to side, changing the direction of its air current
• Motor Capacitor


  An electrical capacitor that alters the current to one or more windings of a single phase AC induction motor to create a rotating magnetic field
• Thermal Fuse


  A safety protective device used to cut-off the circuit when the temperature rises at above normal as designed for the unit
• INTERNAL PARTS OF THE ELECTRIC FAN


  • Selector Switch
  • Rotary Switch
  • Push Button Switch
  • Electric Motor
  • Rotor
  • Rotor Shaff
  • Stator
• Selector Switch


  A part of electric fan that can intensify the produce air for the consumers
• Electric Motor


  The main part of the electric fan that produces mechanical energy to make the propeller rotate
• Rotor


  The movable part of the electrical motor that rotates
• Stator


  The non-movable part of the electric motor that provides electromagnetic energy to the rotor
