Just playing with the rotor...intresting effect with the cap in parallel with the coil

Hi Marius! Nice very clear vid again! :-bd thanks for sharing :) It remember me Hector Rotovert with his cap to speed and increase the torque of the motor ;)

Which voltage did you use to feed the coil? and what did you use as matériel and bearing to make the rotor to support such speed? please.

@Khwartz

I use a 12V car battery and the bearing is a HDD motor from wich i tooked out the inside ring coils ( it produces drag at high rpm). There are 6 HDD disks one in top of another and the mags are 1mm thick and 6mm wide.The mags are super glued. I have allready tooked the rotor at 6300rpm and i'm planing to reach 10 000

Looks like you have nearly 60 mags. About 5Khz out of the coil?  Are the mags nsns? That was a nice effect- improved speed with less input power. My only question is was the motor done ramping up prior to adding cap? Still improving mine. I reached 90k rpm last night. It was cookin. Good idea with the cap... I will have to try placing one in parallel with my coil too.

Nice work as usual. Be careful my friend. Wear ear protection, run it vertical and build a shield.

There are 50 mags NSNS. Today i have replaced the transistor with 2 mosfets and the bemf is realy high. The 56uF/400V goes to 400V in les than 5sec with the usual rising rpm and and less current drain. I'm trying somehow to use the same driving coil as gen coil

is the electromagnetic radiation harmful or not?

@mariuscivic :-bd Wow! You're Genius! Marius :) Fast, Clear and very precise answer <3 With this I start to believe I can do it :D Thanks to give me hope :) and mostly: thanks for your help and sharing.

@mariuscivic Your arrangement with nsns is like mine only I have one magnet. I've had huge inductive spikes coming from my coil with a large ac wave trailing. Probably exactly like you have. My spikes have gone over 1100V. As you probably know your fet's switching speed and Vds rating are key to big spikes. Higher Vds rating = bigger spikes. Bigger spikes better? I think so if recovered and fet properly protected. Recycle. Low Rds value good too. Parallel fets = lower Rds.

Thanks for sharing

have you circuit diagram

Good good!(Girlfriend: " whats than noise, such a freaky noise, .... freaky boy")

Hi marius, nice video, sounds like a jet turbine, scary though with 5k+rpm, those magnets might fly apart, be careful, seems like the capacitor is boosting the drive coil, plus less amperage due to the rotor speeding up.

Keep posting :)
