Through a restrictive process of limiting the amount of electricity to the fan motor.
Fan regulators have an important place in the electrical switch boards. Fan regulators are very similar to light dimmers.Their function is to regulate/control the speed of the fan and provide a convenient environment for the residents. The traditional regulators which are bulky use a resistance having taps and connected in series with the fan. When we move the knob different amount of resistance gets inserted in the circuit. Although cheap the biggest problem with such a regulator is that a considerable amount of energy is lost in form of heat through the resistance. When the fan is operating at low speed the power loss is significant. The technologically superior electronic regulators overcome these problems by using electronic components to control the speed of the fan. Some of the advantages of electronic fan regulators are: 1. They provide a continuous speed control. 2. Power saving at all the speeds. 3. Smaller size and weight. The heart of the electronic fan regulator is TRIAC. TRIAC is a semiconductor device belonging to the family of thyristors.
The higher the speed, the higher the power consumed.
n electrical regulator by using resistance the output voltage is varied simultaneously the speed is varied... But to reduce the the energy loses in the resistor, electronic regulator is introduced,which uses triac to vary the output voltage by varying the firing angle.Which avoids lose of energy in resistor...
no need to check, just replace the whole fan that has a little control module in the fan itself to control the speed as well
A fan regulator is a crucial component that serves to increase or decrease the speed of your fan according to your needs. To understand how a regulator works, you must know something about resistances. Any electrical conductor allows current to pass through it. The conductor however, offers a certain amount of resistance to the passage of current. The resistance depends upon the material of the conductor. 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. The greater the resistance, higher is the voltage drop across it and that lowers the speed of the fan.
The 1988 Ford Tempo fan regulator can be found on the fan hub. The fan regulator is attached to the fan hub with two retaining screws.

Ballasts are not used with motor control.
Perhaps a bad fan resistor
Resistance type Regulator uses Resistance & a selector switch to control the voltage. Actually in resistance type regulator the voltage control is done by voltage drop in resitance (converted into heat energy), which causes energy loss/wastage at lower speeds. Whereas Electronic Regulators uses Triac or SCR based circuit and controls the firing pulse to reduce the output voltage. Here power loss is less at low speed in comparision to resitance type regulator. Only disadvantage in local or cheaper Electonic regulators that at low speed Harmonic occurs which causes humming & heating up of Fan. Now a days Energy saver electronic regulators are also available which do not causes radio interference or haronics.
