4 months agoI’m guessing you watched the first video, the one with a single coil, which, as you said, doesn’t specify those details. However, on a later video ( https://www.youtube.com/watch?v=uNbL3tRZeMQ ), where he makes some improvements to the whole circuit, there are some details mentioned in the description, such as
Input voltage: 24V
Number of coils: 4
Wire Gauge: 24AWG
Coil Current: 13A
Coil ID: 1.1"
Coil OD: 1.4"
Coil Length: 0.5"
Coil turns: 200
The final outer diameter is ~2" due to the addition of steel wire to create a magnetic flux guide or “shell”.
FET Type: IRLZ44N
On time: ~8 ms at max. speed
Energy input per pulse: 2.6J
Ball mass: 65 grams
Ball kinetic energy: ~0.52J
i didnt quite understand the issue, but if you just need -30V you can get another 30V power supply and join them in series (the ground wire from the old and the positive wire from the new supply), then you can use the joined wire as ground, the ground side of the new supply as -30V and the positive of the old supply as +30
