This is a record of a project that's still in development. The eventual goal is that this type of motor/alternator can become a parametrized open source design. A user should be able to enter some parameters, like torque, speed, current, volts/rpm, common magnet sizes and perhaps space available, and a series of 3D printable .stl's and .dxf cut files should be generated. What Drewrt
done is to create a platform that can validate a simulated design, which can then be evolved to a more optimal device by community.
For the creator purposes it can be driven by a variable speed motor (surplus from cordless drill, with step down gearing), and shaft torque input measured, as well as V and Amps out, allowing real efficiency to be generated, and the expected turbine loads to be simulated.
