Discussions on the feasibility of car alternator for wind energy system are still going on. Higher shaft speed means Small wind turbines are equipped mostly with an AC-generator. Some conducted researches utilizing car alternator as generator in wind turbine system are [2][3][4]. By comparison, a small wind turbine with a roughly 60-inch diameter rotor might hit 850 rpm in 25 mph wind! 0000001473 00000 n DIY Wind Turbine Turn a car alternator into alternative energy by building this cheap and easy homemade wind generator. 0000009364 00000 n 0000006629 00000 n Because a car’s crankshaft generally operates at around 1,000-4,000 rpm, a car’s alternator is designed to put out good charging voltage and amperage around 3,000-12,000 RPM. The comparison is based on the energy yield per swept area and cost per energy produced in a low wind speed climate. �K���(���͡�Q�W޳@�DIʴ&��3+�ՎUJ��|�3�3�C��q��z�kz��m��ka�[email protected] �� Permanent Magnet Alternator for Wind Turbine Generator PMA Brand: Inova Wind. The experiment was conducted twice. If your match is “too fast” the wind will overspin the generator will be wasting energy and bearings, or if it is too slow, it won’t will have enough power to spin. The turbine needs to run at some optimal tip speed ratio, so the speed of the generator should change with the speed of the wind. D Engineering Works is a leading manufacturer wind turbine system of Permanent Magnet Alternators, Generators and Torque motors. Using an automotive alternator to construct a wind-powered electrical generator can reduce or eliminate dependency on "grid" power, even if the wind turbine is only used for lighting or recharging batteries. Low speed usually also means low power. By comparison, a small wind turbine with a roughly 60-inch diameter rotor might hit 850 rpm in 25 mph wind! 850 rpm is far below the threshold for a standard Delco car alternator to even start charging a 12 volt battery bank! A tail vane faces the turbine into the wind. Windmills can provide you with electrical power for free – but to convert motion into current you'll need a generator. Small wind turbines need low speed alternators. 0000011766 00000 n Located in the suburbs of Hari Nagar in Delhi, India, it works towards designing and manufacturing innovative and reliable solutions for power generation, transmission and control in the industrial, renewable energy sectors.J.D. 0000022461 00000 n I applied it an automobile alternator, but this component was not a good cho… 81 0 obj <> endobj The operation of the alternator, usually within a vehicle, is simple. endstream endobj startxref This rotary movement is transferred to the mechanical components of the car causing movement. Turbine Powered: These wind powered cars have a wind turbine at its tail end. 0000001603 00000 n There are three different types of AC-generators: the synchronous generator (also referred to as alternator), the asynchronous or induction generator and the permanent magnet generator. 0000001729 00000 n h��X_o�8�*zl�k�?�-C�4i��6h{��}�75�$E��o$-)���i��j(�)���iւ'�3�S&���0a4̖I��3�̂)!a�,����1�Z @ːH„�`G�L*�€�V�Br0���`�L��e 850 rpm is far below the threshold for a standard Delco car alternator to even start charging a 12 volt battery bank! endstream endobj 82 0 obj <>/OCGs[107 0 R]>>/PageLabels 77 0 R/Pages 79 0 R/Type/Catalog>> endobj 83 0 obj <>/ExtGState<>/Font<>/ProcSet[/PDF/Text]/XObject<>>>/Rotate 0/Type/Page>> endobj 84 0 obj <>stream In this video I will explain how I cracked the car alternator code, that is how to use it for a wind turbine/generator. Wind Generator With Car Alternator: A few years ago to build a wind generator, with which wanted to charge a battery to power a refrigerator and a radio in my small farm, where there is no electricity supply. It is your first step in achieving self sufficiency as windmill will enable you to charge your car batteries and meet a major chunk of your home’s electricity requirements through wind energy. Doing so can help you cut down on your electricity bill or allow you to use a turbine in a remote location to power a water pump or an RV. Wind powered electric generators are obscenely expensive. %E���UZ'�4SE2��#��:i�iV%�4�&�ʟ�T[���+�l�g. alternator and the power electronic blocks, and emulating the wind turbine with an AC motor. However I bought a small Hitachi alternator for 1/3 of the price of one rare earth N35 Neodymium magnet, typically one uses 24 of these magnets in a wind turbine… atR��¶��R}�H 0000002241 00000 n Even if you don't have a GM alternator you … 509 30 But any time you are using incoming wind to generate power, that means that the car will be slowed down be the drag created by the wind turbine. 02, No 1, pp 1-10, 2011 ISSN 2088-6985 1 EXPERIMENT AND ANALYSIS OF CAR ALTERNATOR FOR WIND TURBINE … Thus an alternator can never serve to generate busy energy by a small turbine driven by the wind, as it does in a car, because here the alternator is driven by power from an internal combustion engine, nothing comparable to the force exerted by the wind on the blades of a small turbine. It would take a hurricane force wind to turn a small wind turbine fast enough to even start charging a battery. If you are considering using this alternator to generate energy, try attaching it to a pole and mounting a blade type fan or propeller to the shaft. 0000015714 00000 n 0000022170 00000 n With a little work, you can convert any GM alternator into an electric generating wind turbine. During tail wind the wind energy will rotate the turbine. The average backyard engineer can construct a wind power … 0000002075 00000 n 12 Volt PMA includes built in bridge rectifier for DC output 1.

A built in rectifier converts the electrical output to DC, ready to connect to a battery. An alternator can be easily acquired; making construction of a small wind turbine generator a perfect choice. I was wondering if it was possible to grab a car radiator fan (which has a 12V DC motor), face it into the wind, and turn the motor into a generator. Journal of Mechatronics, Electrical Power, and Vehicular Technology Vol. All well and good in theory. 0 0000006135 00000 n The alternator design is integrated into a simple tower-top mounting arrangement (called a ’yaw bearing’). xref H�Yi=�S]u���cչ��|��e2[]� �=b�7K���~ڝ=c�������������>�S�E�"�c���4�Ս[#w:�M����Ҋ@˂�(X5�ҙQy�=��e�S����Ĭ�!.^ u�JR�)���ϵH)R1 9�t��L^D��֮n��t�,7����3ZȨ7��u�v�V�0}x Ű҇�� �:��ܚ�"EX� *�#G�.- �N�ot�M#y ISE���bhbљVM�`�=WX+��z2����i/����י�_o6�}���T4r�,8���3ӺMS�z�#��WDMjGM�I�����$�+&)Sb���[;E����]"���.C� �M"u)�4Y��ؤ9�"���;Ck��@n�^5ĉ�� ��M�� %%EOF As this video shows, car alternators are not ideal candidates for a homemade set-up. 2.9 out of 5 stars 5 ratings. 0000005882 00000 n Story and photos by Robert D.

The shrouded wind turbine with a brimmed diffuser has demonstrated power augmentation by a factor of about 2–5 compared with a bare wind turbine, for a given turbine diameter and wind speed. Cut-In Speed--A wind generator does not start pushing power into the battery bank until the generator or alternator voltage gets higher than the battery bank voltage. 0000000896 00000 n The connections coming out of the alternator are something else. The only time this would actually be net positive would be when there is significant headwind. endstream endobj 524 0 obj <>stream 0000014620 00000 n 127 0 obj <>stream Research [2] used a Windpro2004 wind turbine that could generate 163W electric power with wind speed around 9m/s and the selected gear ratio was 1:4. 0000008083 00000 n The rpms have to be much higher before any effective energy is drawn through the alternator. Although the turbine itself doesn't require much space, to avoid potential conflicts with neighbors, you should generally have at least half an acre (0.2 hectare) of space for a turbine that generates up to 3 kilowatts of power and a full acre (0.4 hectare) for a turbine that generates up to 10 kilowatts.
