Motor Layouts
As prepared by Tim Harwood, March, 2006.
Various layouts can be employed for the CD motor template.
Layouts
Single stator
The single stator layout minimizes duty and is easy to build
Dual stator
The dual stator setup was preferred by many experimenters because it offered smoother torque transfer to the rotor.
Triple stator
The triple stator setup optimised torque while still being relatively easy to time.
Eight stator
Beloved of those who dream of selling home power kits. The facts of experimentation often proved dissapointing.
Magnet layout
Alternate N/S
Certainly works better if generator functionaly is required. In terms of torque, the gains were less readily apparent.
General observations
The over-unity effect comes the the stator zone. More stators just means more throughput and / or better torque. It does not necessarily mean more efficiency. There was never anything magic about 8 pole rotors. It just makes the apparatus harder to build because of the increased rotor mass.
Torque optimized
I have never built this design, but if you wanted torque, I would imagine this would be the best layout for this purpose. Obviously, ganged up on a shaft, this layout would multiply torque. 4 pairs of rotors, each slightly out of phase with each other, would deliver more or less continuous torque to the main shaft. Adjacent magnet spacing, and opposite magnet spacing, would need experimental feedback for full optimization.
Obtaining conventional AC output
The main drive shaft can be used as an output converter for the motor. That is to say the cold current / back-emf can be used with its voltage gain to recharge the source battery, providing a system that delivers shaft motion until component failure, and then something akin to the Bill Muller 7/8 wheel (http://www.mullerpower.com/index2.php) placed on the end of the shaft, as a separate output device. Thus the output is conventional amp rich AC, while the device itself functions off exotic negentropy voltage gain physics. Because under this system the source battery(s) will be kept permanently topped up, they should last a long time in good condition, further enhancing the practicality of this proposal.
