Magnetic Levitation VAWT - 17 Feb 2011

This vertical axis wind turbine uses a permanent magnetic bearing to support the vertical forces. Only small conventional bearings are needed to support the side forces. Next additions will be hall effect sensor to log rpm and PIC processor to record RPM, voltage and current
and allow us to cross correlate with our weather station wind data which is being archived. This will allow us to determine whether design modifications help or hinder power output.


Neodymium ring magnets (2" x 1/2") are used for the actual levitation. These same magnets are used in the alternator thus reducing the number of different parts needed to build the turbine. Small roller blade bearings are used to handle the side forces.
