RENEWABLE ENERGY CLUB
 
 
Maharashtra Energy Development Agency (MEDA) sponsored to setup the Renewable Energy Club in our Institute, in order to create awareness about New and Renewable Sources of Energy among the students. Renewable Energy Club was started on 01.01.2007 at our College under the guidence of Prof. D.R. Pagay, with the grants of MEDA. VESIT will certainly create awareness in the society, especially among the young minds to realise the importance and uses of the renewable energy. Every year we conduct a written test and arrange talks on non-conventional sources of energy.
 
A wind turbine is a rotating machine which converts the kinetic energy of wind into mechanical energy. If the mechanical energy is directly used by machinery, such as a pump or grinding stones, the machine is usually called a windmill.Wind power occupies less land area per kilowatt-hour (kWh) of electricity generated than any other energy conversion system. While most renewable energy projects and production is large-scale, renewable technologies are also suited to small off-grid applications, sometimes in rural and remote areas, where energy is often crucial in human development.
Our aim is to use wind power to run small generators to generate electricity and other appliances in which mechanical energy can be directly used. Also a person with sufficient technical knowledge should be able to construct and maintain it.
 
FAN Waveform
By keeping these constraints in our mind, we started making a windmill that is easy to construct, cheap & uses the parts those are easily available in the market. Small windmills rotate at 40-60 rpm. So by converting a ceiling fan motor into generator we can avoid use of gearbox. Ceiling fan motors have generally 12/14/16/18 poles that make them suitable for making low power & low cost generators.
MOTOR Windmill Installed on top of the tank of our college building.
Lamp Test
In order to generate more power we converted a
3-phase, 6-pole motor into a generator that was driven with gear mechanism. But due to permanent magnets cogging problem arises that requires higher torque to overcome it. Then also results are quite satisfactory. Output of generator is converted into D.C. by means of 3-phase rectifier & is used to drive lamp load.

Projects Under Construction

Horizontal axis windmill – 16 feet diameter.
Vertical  axis windmill – 6 feet diameter, 2 feet height.
Coreless Generator with more number of coils.
Reduced cogging 3-phase 12-pole generator (1KVA) with improved winding.
Electric Bicycle.

 
Proposed Applications – Mechanical, Electrical

Directly driving a synchronous motor which will drive cooler compressor etc.
Water Heater- useful for hill station resorts.
Water pump.
Community washing machine
