The document summarizes the key parts of a table fan, including the fan motor, main body, fan blades, regulator, and oscillating mechanism. The fan motor is typically 60-70 watts, uses a 4-pole induction motor with a starting and running winding in a capacitor start capacitor run design. The oscillating mechanism uses a mechanical design to partially rotate the fan in a semi-circle at 4-5 times per minute. The fan regulator controls speed by inserting more or less resistance, and the fan blades are usually made of steel or aluminum with an aerodynamic 3-4 blade design.
7. 60-70 Watt
4 pole, 1 phase induction motor
Stator winding is of two parts:
• Starting winding
• Running winding
Capacitor start capacitor run type
8. Oscillating mechanism
Used to partially rotate fan in semi circle area
Mechanical design at back side
Facility to ON or OFF
Osciallates 4 to 5 times per mintute
9.
10. Fan Regulator
Resistance is inserted to control speed
More the resistance, lesser will be the speed
And vice versa
11. Fan Blades
Made of Steel or Aluminum
Three or Four blades
Aerodynamic design
