Add-Ons (this list will keep growing so come back and check out new features for this alternator)

 - Overrunning clutch: Check it out!

 - Dual stage 1:4 Gear box for A-F: Check it out!

Key Features:

  Dual Rotor, 12-Pole Configuration – Magnetic fields pass through the stator for efficient induction.

  9-Coil Stator – Optimized coil arrangement to demonstrate power generation principles.

  Adjustable Magnet Setup – Each pole can hold up to four 30mm × 2mm N52 neodymium disc magnets, but spacers are included for      those who prefer fewer magnets per pole.

  Modular & Expandable – Some parts are swappable, and future versions will introduce new configurations and components.

Material List:

Example Coil Winding Information:

  -Voltage & Current Output – Varies based on RPM, wire gauge, and turns per coil.

  -Coil Wraps – Typically 20-50 turns per coil, with higher turns increasing voltage output.

Wire Guide:

 -16 AWG – Handles ~10A, low resistance for high-current applications.

 -18 AWG – Supports ~7A, balancing current capacity and ease of winding.

 -20 AWG – Supports ~5A, ideal for lower-power experimental setups.

Future Upgrades & Modular Design:

 This is just the first version! Future models will include:

 Different coil and pole configurations for varying power outputs.

 Alternate magnet arrangements to explore performance changes.

 New modular components that allow users to easily swap out parts for customization.

P.S.

  If anyone needs help feel free to reach out in the comments. I will gladly share my knowledge of what i have learned. I love critiques and concerns as well; Im trying to make this as easy of an educational model as possible! Thank you and i hope you enjoy! 

Also my coils in the picture are way to big follow the 20-50 turns for 12-16awg and lean more to 40-100 turns for 18-24awg. Feed back on the new coil cases would be great seem to be easier then the free floating coils.
