Building Instructions, Photos, and Schematics

Schematic for Switching Coil, Re-Capturing, and Using the Back EMF and Inductive currents into a cap and load while generating coils are added and this energy is sent to the recovery cap.


This design was built for energy recovery of the back inductive currents by storing them to a large micro farad cap while being released into a load.

Here you ca see a timimg mark on the rotor as well as the 45 ohm magneto coil between the dirve coils.

Here you ca se the single steering diode connecting the caps. The cap on the right is the drive cap and the cap on the left is the recovery cap.

Here is a view of the VCR motor I use as a disipating load on the recovery cap. I monitor the caps voltage for efficiencey.

Here I start to experiment with double switching to divide the current draw on the switch and also to increase the Internal Switching Frequency.
