Working and construction of electric fan

An electric fan is an electric motor to which the blats are fixed so that then the motor of the fan rotates ,the balds through the air A D.C fan are of DC series motor in which the rotating part armature is connected in series with the stationary part and when the current is given to the motor , the magnetic field is set up in the field winding which experience a force in the armature to move it at right angle to the feed and balds attached with shaft of armature displaced the air. the same principle ....etc

ABSTRACT
Urban electrical power systems with steep demand increase need easily located solutions with short lead time from decision to transmission. While AC cable solutions can offer sufficient power ratings, the problems of load controllability and short circuit power increase with every added circuit. These problems may be countered with Voltage Source Converter (VSC) based technology using Cables for transmission, such as HVDC Light. This technology offers up to 500 MW per station with small footprint, ideal for in feed to city centers. ....etc

automatic room light and fan controller doc

ABSTRACT

This paper reports on a system that can save electricity. Many times we leave the room and hall without switching off lights and fans, thus electricity is wasted. In this work we have presented a system in which energy will be saved based on number of people entering in or leaving out of the room.
If there is no person in the room, then light and fan will be switched OFF. On the other hand as soon as any person enters the room, light and fan will be switched ON. On the basis of the intensit ....etc

Bladeless Fan

A bladeless fan (sometimes called an air multiplier) blows air from a ring with no external blades. Its blades are hidden in its base. The first concept was created by Toshiba in 1981. Dyson claims that its bladeless fans (U.S. Patent 8,454,322) produce a more constant airflow than traditional fans.

The air is drawn in by a fan in the base and then directed up into a ring. It comes out of a crack all around the ring and passes over a shape like that of an aircraft wing. Industrial designer Sir James Dyson named his fan the A ....etc

light controlled digital fan regulator pdf

Mans are born of habit, and we all want comfortable. At night while sleeping we often switch of the light. But sometime we used to increase or decrease the speed of fan. And it is very difficult to trace the switch board in a dark room at night and to wake-up from bed is also irrigative. By keeping this problem in mind the group of electronics geek at Dreamlover technology designed and verified a circuit light-controlled digital fan regulator. By using this circuit one can control the fan speed with a ....etc
