Design of efficient, cost effective three phase induction motors for ceiling fans in India
type: CreativeWork
description: In developing economies such as India, improving the efficiency of home appliances is of high priority in locations which are characterized by a weak electric distribution system. Ceiling fans are one of the most used home appliances in India. They typically operate for many hours, and since most of them are driven by inefficient, low cost single phase induction motors, the total power loss is nontrivial. To overcome the inefficiency of single phase induction motors, brushless dc motors have been increasingly used in ceiling fans to achieve high efficiency and power factor at multiple speed settings. However, they are more expensive than conventional ceiling fan motors due to the additional cost of permanent magnets and power electronic drive circuit. Three phase in contrast to single phase induction motors have proven to have a superior performance especially for high power applications.
