What actually happens when you change the speed of fan?

As when you control the speed of your fan you are actually controlling the voltage drop. This voltage drop actually generates heat inside the regulator, which does not affect the current flow or the current consumption at all.

How would you increase the speed of the fan?

How to Increase the Speed of a Ceiling Fan

1. Eliminate vibration in the blades.
2. Lubricate the fan’s moving parts.
3. Turn on the fan and see if basic cleaning has increased fan speed to its original settings.
4. Check the pull chain switch on the fan.
5. Check the wires where the pull chain switch is wired to the fan.

How does a fan speed regulator work?

They control the voltage across the fan is controlled by a capacitor, the voltage across the fan determines the fan speed. Capacitive regulators are energy efficient with linear speed control, quiet operation without humming noises and highly reliable than electronic type regulator.

What is regulator fan?

A Fan Regulator, as the name suggests, regulates or controls the speed of the fan motor. Before dealing with the fan regulator, a brief discussion about the fan motor is necessary, as the main purpose of the regulator is to control the speed of the fan motor.

When the speed of an electric fan increases the current?

If you are increasing the speed of the fan by using a speed controller then as you increase the speed the current must increase. To give examples. a fan with a speed controller on 1 it draws 4 Watts and on 9 it draws 45 Watts. A more than 10 fold increase in power consumption.

How can I increase fan speed without regulator?

The speed of Fan can be slow down by simply by connecting a bulb or any other resistive load in series between the power supply and fan. In this method if the watt of connecting Load is increased then the speed of Fan is also increased.

Why does fan speed reduce?

The main reason for reduction of speed of old fans is wears & tears of ball-bearings due to friction. Voltage fluctuations and the problem in capacitors of old fans are another two reasons for reduction of speed of old fans. In case of wear & tear of ball bearings, the old fan is required to be replaced by new fan.

Is fan regulator save the power?

The speed of a fan is controlled by a regulator. In electronic type of the regulators the consumption in the regulator is minimal and using them definitely saves the electrical energy in reduced speed mode of a fan. In fact there is an significant saving of about 30-40\% from full speed to minimum speed.

How does a fan voltage regulator work?

The regulator has spools of wire with different amounts of resistances. When you set the knob at a particular position, you include a certain resistance in series with the fan. A series connection implies the resistance is in line with the fan. This reduces the voltage drop across the fan and its speed to your desired level.

What happens when a fan is turned on at full speed?

At full speed the resistance is zero. To decrease speed we increase the resistance by turning the knob. ( Usually by steps). This will cause some voltage drop across the resistor. So the fan terminals receive a reduced voltage.

How does capacitance affect the speed of a fan motor?

Now, when you increase the capacitance, the voltage across the capacitor decreases but that across the fan motor increases. Accordingly, the speed of the fan increases. In other words, you need to increase the capacitor value to increase the fan speed.

How does a capacitor regulator work?

The idea behind a capacitor regulator remains the same, which is to adjust the voltage across the motor of the fan. Now, when you increase the capacitance, the voltage across the capacitor decreases but that across the fan motor increases. Accordingly, the speed of the fan increases.
