Dave W, your PM box is full... plz deleat some PM's so i can send you a PM

Hi, At the 2016 conference where JB demoed the ZFM, when i noticed that ZFM circuit did not have a Output Diode Bridge like a window motor...

Joster, The single NPN transistor SG type circuits are Energizers with Low Torque. The Bipolar circuits are High Torque circuits with energy...

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...

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

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...

Here are pics of the Ferris Wheel Hub Motor Timing wheel. When I received the FW, the 5, 1/2" magnets on the timing wheel were missing. You could...

Hi, 1. Never run or test a JB SSG without the output battery hooked up...! Just asking for your transistors to blow up or be weakened.... 2....

This video shows the Hub Motor pie shaped magnets field shape using Ferro Fluid https://vimeo.com/375038141

This video shows the Hub Motor pie shaped magnet field using brake drum/rotor filings that were rusted, and used for various experiments over the...

Video of the magnet field sensors on the ends of the pie shaped magnets on the hub motor https://vimeo.com/373782870

Video of the magnet field sensors over the center of the pie shape magnets on the hub motor ...

For this series of experiments on the Pie Shaped magnets on the FW Hub Motor I used the Linear Hall Effect magnetic field sensors A1326LUA-T ...

here are pics of the Hub Motor with my measurements of the magnets & space between magnets on blue tape

Joster, A trigger strand on the coils would most likely work on the ZFM the same as a Window Motor........

Yaro, What kind of Bipolar B/C circuit arrangement are you going to use to drive this 3 coil ZFM...? this is Very different than a 2 or 4 coil...
