How do table fan motors work?

The operating of an addict is kind of easy. it primarily contains a single-phase induction motor. The fan condenser torques up the electrical motor, permitting it to start out and run. Associate in Nursing electrical current reaches the motor and so enters coils of wire that square measure wrapped around a metal base.

How do fan regulators work?

A ceiling fan has an electrical motor and antimonial blades connected to that. after we start an addict, the voltage distinction causes the present to labor under the motor and therefore the fan rotates. The regulator controls the voltage that produces the present flow less or a lot of.

How Conventional Fan Regulator works?

This is the previous Fan Regulator. As you see within the below figure, the development of a traditional fan regulator is extremely easy. there’s some series-connected resistance that may be adjusted by rotating the knob of the regulator. This standard fan regulator is to be connected nonparallel with the fan and power provide. By moving the knob we will increase or decrease the resistance worth. If we tend to increase the worth of resistance the free fall across the electrical device is redoubled that the voltage across the fan motor is faded and ultimately the speed of the fan is faded and Vice-versa.

The disadvantage of the standard Fan Regulator is that it causes a large quantity of warmth loss or I2R loss as a result of there ar variety of resistors which causes heat loss across the resistors and eventually this reduces the lifetime of this regulator and conjointly it affects your electricity bill therefore.

How does Electronic Fan Regulator Work?

To reduce power loss nowadays electronic fan regulator is mostly used. Electronic fan regulator uses semiconductor devices.

An electronic fan regulator has the following parts,

 

  1. TRIAC
  2. DIAC
  3. Capacitor
  4. Fixed resistor
  5. Variable resistor or Potentiometer

As you see within the below figure the TRIAC is connected asynchronous with the Fan and therefore the provide. The TRIAC will conduct AC current once a pulse signal is given to the gate terminal of the TRIAC. Here the DIAC is employed to trigger the TRIAC. First, the electrical condenser is charged through the mounted and rheostat resistors. once the electrical condenser is absolutely charged it starts discharging through the DIAC. currently the TRIAC is triggered and it starts conducts, therefore, the present can ensure the availability through the TRIAC and therefore the fan.

Actually, the TRIAC remains ON for a brief time period and remains OFF for a brief time period in line with the charging and discharging of the electrical condenser. This method causes scale back the worth of the typical voltage across the Fan and ultimately the speed of the fan is bated.
