I Finally Got the SSG Running My 4 Magnet 180-Degree Pulse Motor

Hook

I saw a cool SG bini motor on the Overunity Research channel and decided to try the same idea on my own 4 magnet 180-degree pulse motor. With the triggers swapped it runs smooth on just 5 volts and the external coils keep the amp draw tiny.

Watch this experiment

I hooked two 20-gauge and 30-gauge bini coils at exactly 180 degrees. All magnets face north for now. The trigger strand on one side fires the opposite coil and vice-versa. Turned on at 5 volts: 5.66 V and 0.1 A. It spins right up.

What you'll learn

You will see how external trigger coils lower current while still giving a strong double hit every rotation. We also check Hogen lights instead of neons, talk about magnet orientation, and note the wobbly top toroid that needs fixing.

From the bench

The bench is literally dipping in the center so nothing sits perfectly flat. I measured 0.1 A at 6 V, about 2 A at 9 V, and the Hogen lights start glowing around 12 V. The 666-turn 20-gauge triggers are a bit slow until the top magnet gets recentered.

How it works / what we changed

I swapped the inputs so each trigger strand fires the coil on the opposite side. This gives the benefit of an external trigger without using an extra rotor slot. The double whammy at 180 degrees kicks the rotor twice per revolution and it starts instantly even at 5-6 volts.

Coil first

I wound the trigger coils first using 20-gauge wire with 666 turns each. These sit outside the main drive coils so the electrification stays separate. That keeps the amp draw lower than if the trigger was wound inside the drive coil itself.

Using run his magnet

Using the SSG circuit to run his magnet setup at 180 degrees worked better than expected. The external triggers let the motor spin faster with less current while the Hogen lights act like resistors until they light up around 12 volts. I plan to extend the shaft, pry the top toroid off, and add more coils later.

Run his magnet 180

Run his magnet 180 setup with the two bini coils at opposite sides gives a nice double pulse every turn. At 12 volts it stays fairly stable even though the table dips and the top magnet is slightly off center. Flipping all magnets from north should create a stronger clamp on the shaft and smooth it out more.

Builder checklist

• Two bini coils (20 ga & 30 ga) mounted exactly 180 degrees apart
• External trigger strands swapped to opposite coils
• All rotor magnets facing the same direction initially
• Hogen lights or neons across the drive transistors
• Measure voltage and current at 5 V, 9 V, and 12 V
• Check shaft runout and top toroid centering before speeding up

Troubleshooting

If it shakes at higher voltage, the top toroid magnet is probably off-center; I need to pry it off and recenter it. The table dipping in the middle makes everything wobble, but I am continuing experiments anyway. If the lights do not glow, they are still acting as resistors and the circuit is still working.

Safety

Keep voltages low (5-12 V) while testing. The Hogen lights get hot when they start conducting. Watch your fingers around the spinning rotor with neodymium magnets. Always disconnect power before adjusting magnets or coils.

FAQ

Why swap the trigger wires? So each external trigger coil fires the opposite drive coil and we get the low-amp benefit without extra rotor slots.

Do the Hogen lights replace neons? They seem to work around 12 V where regular 90 V neons would fire. They act as resistors below that point.

Can I flip the rotor instead of the magnets? No, because the coils are wound for a specific pole orientation. The magnets have to be pried off and reversed.

What is the double whammy? The 180-degree placement plus swapped triggers gives two pulses per revolution instead of one.
