Machine Rotor Construction Rotating Table
Rotor Construction Thumbnails
My current project is to construct a single levitating motorized ring or rotor within a frame about 2400mm across. The rotor is about 160mm wide, and the frame about 300mm wide. I will not be fitting the components required for lateral acceleration. This will be to test for vertical lift/acceleration only. I am attempting to design something which can be added to later for lateral acceleration, if required. The rotor on this model will be only about 20mm thick as I will use the known magnetic characteristics of a single rare earth magnet between two ferrite  magnets, to levitate the ring. My full design may utilize a thicker rotor more like an airplane wing, probably more structurally sound, and easily able to accommodate the lateral acceleration components. This would have rare earth magnets top, bottom, and side. A full machine would require two of these rotors, counter-rotating. The current design can also be easily modified  into a dual rotor machine if required.

Plans & Circuits
The section under the FRAME menu item is incomplete. It requires details on the Guide Wheels construction  and operation. This information will be added if this subsystem works as planned.
The section under the DRIVE menu item is incomplete and subject to change. It contains a lot of information on the general direction of the progress of the electronics and electrics.
Various Pieces Of Test Equiptment
Photo of 2 of the 6 guide wheels. A lever arm has 2 electromagnets to retract or extend the wheels and latch in place. A car door lock keeps the wheels locked in the extended position for startup or shutdown. Hall sensors tell the micro computer if the wheel is located correctly. Micro programmed to pulse the wheels to absorb any startup  vibrations. Using Picaxe 40X2 Micro.

Everything above the table is machine. The Rotor is the Blue and Red alternating magnets.
A small video of the motor running can be seen here. Photo Sept 2013. Guide wheels automation still not functional.

Rotor speed will be controlled by the micro to cycle off and on at a set range. With no actual load and no friction the motor could keep accelerating to a point of self destruction. 

The rotor weighs about 30 Kg
but can be rotated easily with one finger. The startup power was measured at about 180w,
but I would expect this to drop considerably as the running speed increases.
