A laser cut adapter plate was made that matched the drain holes and lug studs of the trailer hub. Drill holes were marked on the five flat embosses using the adaptor plate as a template and then drilled out to accept a 1/4" bolt.
After the holes were drilled, the studs were removed from the hub using a hammer and a large socket to support the casting. The adaptor plate was placed on top and the studs were pulled back in place using a stack of washers and the lug nuts. This is necessary to get the proper spacing to mount the stator.
A special collet was made to mount the stator to the trailer spindle (axle). This way the stator's position can be adjusted. The four bolt BT8 trailer hub and spindle is rated at 1200#.
I plan on making a "Kit" available soon with a Stator, Magnetic Hub, Adaptor Plate, and Collet. Keep checking back. I'm also working on a HAWT that uses the same concept.
This is one of the VAWTs that I have in mind.
Let me know if you are interested.
