Explorations of the Bedini Ferris Wheel Motor Energizer

I had planed to take inductance and resistance measurements of the FW Hub Motor coil's this weekend to post along with these pic's...

My 20+ year old LCR meter was dead in the water when I unpacked it from the box it was moved in... So I had to buy a new one, and will post the measurements next weekend.

following this closely....amazing stuff!!! What kind of circuit is this? i remember John saying "it's a highly modified Bedini Cole Switch" any chance on reverse engineering a schematic?

I've already reverse engineered the circuit, and have made PCB's of my version of the circuit

nice! thats so cool! is it indeed a modified bedini cole? any chance of sharing the schematic?

It is a modified B/C bipolar circuit. The Hub motor has 3 sets of bipolar transistors and the main wheel circuit has 5 sets of bipolar transistors.... I will post the circuit schematic at some point soon, I dont have it on the tablet.... I have sold several of these PCB's, so it is out there...

Aaron,
The waveform wheather it electrical or magnetic its all the same as you rightly expressed, either of the circuital parameters show the same significance.

Hey RS,

Please forgive my ignorance but I need to ask a question. What is the difference in functionality between a single NPN transistor switch to pulse the coil and a single set of bipolar transistors? Doesn't a single set do the same thing as a single transistor? I mean, I have seen some guys on youtube use "half of a Bedini-Cole" and so have I. But it is really just on and off, no polarity switching like with a full Bedini Cole switch. I know I don't fully understand the situation thus my question. Just looking for some enlightenment. Thanks!

Joster,

The single NPN transistor SG type circuits are Energizers with Low Torque. The Bipolar circuits are High Torque circuits with energy recovery from the coil that can be used in several ways. The 1/2 H Bridge bipolar circuit can only drive a single polarity coil, against a single polarity magnet, and is what the 2 different Ferris Wheel circuits are. A Full H Bridge bipolar circuit can drive alternating polarity's on the coil against alternating polarity Magnets, and is what the ZFM and Window Motor circuit's are. My PCB's are designed so that they can be used as a 1/2 H Bridge bipolar circuit like the 2 FW motors, or with 2 PCB's mounted back to back it forms a Full H Bridge bipolar circuit that can run a really BIG ZFM or Window Motor.

Hope this helps your understanding.
