Magnetic levitation using neodymium magnets for vertical axis wind turbine (VAWT) II
Published 2012“…This project involved the design and fabrication of a test model vertical axis wind turbine, however as this experiment was carried out indoor without any wind condition, the author used a dc motor to simulate the wind required to spin the turbine. The advantage of this motor allows the author some control over the speed of the turbine. …”
