Abstract: In tropical countries room temperature dips to 4 C in winter and newlinerises to 46 C in summer and the costeffective way of achieving comfort newlineduring summer is through the use of domestic fans rather than air newlineconditioners Since the ambient temperature variation is wide as mentioned newlineabove speed control of domestic fan is essential newlineThe motor used for domestic fans is a capacitorrun single phase newlineinduction motor with squirrel cage rotor The rotor resistance in these motors newlineis higher and it is therefore quite suitable for wide range of speed control newlineusing stator voltage control The commonly employed method of speed newlinecontrol in domestic fan motors is the use of a variable resistance in series with newlinethe stator of the motor As this scheme is cheaper it is popular even today newlineHowever this is an inefficient method of speed control due to the power loss newlinein the series resistance In the alternative schemes the triac is inserted either newlinebetween the ac mains and the fan motor or in series with the main winding newlineThough the triac based schemes are simple reliable cost effective and newlinesuperior in power savings it suffers from various drawbacks such as newlineincreased harmonic content and poor power factor especially at lower output newlinevoltages newline newline
