How to make AC generator "Permanent magnet alternator" from old Hard disk drive magnets: Urdu video tutorial about making of AC generator (PMA Permanent magnet alternator) using old Hard disk drive magnets. This generator produce 12 volt and 0.5 amp at around 1000 rpm and can be used for charging mobile and other devices.
What is AC Generator?
The AC Alternating Current Generator. An electric generator, or dynamo, is a device which converts mechanical energy into electrical energy.
Why we make AC generator: The goal of this project to design and manufacture a permanent magnet alternator" from old harddisk drive magnets that could be mounted to the dual rotor vertical axis wind turbine. The budget for the project is very low and need good results so we decide to get powerful neodymium magnets from hard disk drive. The generator had to be capable of producing 5Watt of power with a 12 V output in order to limit the current and heat produced .

I acquired 10,000 magnets from a server decommission project here in the United States. I have so far built 100 modules using a very similar setup to what you have created. I am planning on using the modules in a series / parallel. I have setup the windings to produce 6 phase ac that I will rectify,
regulate and then convert the power to single phase 120 Volts AC. My eventual plan power the alternator from a vertical axis “egg beater” wind turbine. Nice to see the Internet being put to use to share these ideas.
Good work! It help us teaching basic concepts to our students. Congratulations.
What have u used to stick coils to the base ? Please tell me . I’m working on it at the moment .
Is it Ok if there is much gap between two consecutive magnets ?
Great work admin can we make use of such device in Air conditioning with 3000w/h 15A 240vac 60htz duty cycle
