Floating Motor

[@zees9669]

I wish you were my teacher back in my school days. I just love your explanation and presentation. Thank you very much Sir.

[@daveboyt6810]

Nice. I built a similar one years ago, but the reed switch didn't last long at high rpms. A hall effect sensor might be a good alternative.

[@Lidmotor]

Great replication! You took the idea and made it even better. That is what I love about this hobby. People share ideas and as a project moves along we add our knowledge and experience and improve it. Well Done!

[@ludicscience]

Thanks so much!

[@Apollo-p1l]

Fantastic little motor. Great video again. I love your little machines.

[@chance1986]

Nice version of this suspension system. It's well-balanced, and the addition of the white collar on the shaft stops any wobble at slow speed. It probably adds a little friction too, but not much.

[@strongholds12]

chance encounter grease it 🙄

[@Guishan_Lingyou]

What a cool little motor! I'm going to make this with my kids.

[@ludicscience]

Glad you like it!

[@Kapalek84]

Very nice motor, the solution for magnetic suspention is awesome👍🏻

[@ludicscience]

✌

I think Lidmotor usually included an LED or a diode allowing for the transients (flyback) voltage spikes to be sent back to the PSU instead of possibly causing a small arc at the reed switch. Maybe the reed switch your using has a built in protection diode? Excellent video, really enjoying your content as it comes out.

[@ludicscience]

I just forgot the diode 😁

[@davemwangi05]

what happens to the reed switch without protection? I usually don't take it seriously to include a flyback diode.

[@BinjKomisar11]

@@davemwangi05 If you drive the ciruit with a high enough voltage it will likely eventually spot weld the reed switch shut (I know this from doing so and having it happen to myself). If you drive with a low input voltage your should be able to get away without damaging the reed switch.... But, best practice in this case, is putting in the flyback diode. And if you want to play around with raising the input voltage relatively higher (say 5V or more) then the diode is a really good idea. You can use any diode (other than certain spec zener), even LEDs work. LEDs are particularly cool because you can see the flyback pulse as its created which is kinda cool (in my opinion anyhow). Peace

Thank you for sharing. Perfect suspension idea

What's magnetic switch

[@maxprophet2401]

Just after 5:43 when the rotor hits pause, an example of weirdness in magnetics and why it's intriguing.

[@chance1986]

This is caused by the rotor magnet attraction to the reed switch itself. The reeds themselves must be a ferromagnetic material in order to work. And the leads are usually a ferromagnetic metal too.

[@maxprophet2401]

There isn't enough magnetic material in the reed switch to instantly stop the rotor like that. The rotor magnet did close the reed switch, you can see it bend upward slightly as the ammeter on the power supply climbs from zero. I didn't notice the power supply was even on at first and I actually thought it had been edited. For the most part I agree with ya and I'm glad you said something because I'd missed some things.

[@ludicscience]

The rotor just got stuck in the reed switch

[@maxprophet2401]

It piqued my interest with LUDIC SCIENCE!

[@rimbacahyo8362]

Awesome dude. It's like magnetic suspension

[@bhimsah2097]

Sir there is possible to make solar to absorb light from our Room light like 0volt or other which we used in our domestic application. Plz

Hi! Could you help me out with something I have been wondering about. 1. When reading about electric vehicles people always talk about the amps and not the voltage. Like this a x amp battery. The more amps the better they say. I really don't understand that. Why not talk about Watt hours? 2. This is about energy efficiency and it is a bit complicated for me to explain but I have this electric bike and a 15 Amp controller. I could either increase the amp or the voltage to make the bike go faster but what would be the best to do to make it most energy effective meaning saving the most battery power? Appreciate your help with this.

[@heavycurrent7462]

1. The amp in that sense is directly proportional to the torque the vehicle can deliver with that battery. Higher voltage can also increase the power output, but usually the motor has a standard voltage to operate on, so increasing the voltage for more power is not very suitable. 2. Both is the same. The power dissipated by the battery in the end, is the product of Voltage and Current. So if either one remains the same while the other is increased, power consumption is equal for both options.

[@nattsurfaren]

@@heavycurrent7462 For the motor do you mean standard voltage as in continuous power at a certain voltage without any damage occurring on the motor? For the crystalyte hub motor I have on my ebike it is set for 2000 W continuous drive. But for batteries some people speak only amps as if voltage wasn't important. However for electric bike we have 24 Volt , 36 Volt, 48 Volt and 72 Volt. Now for question 2 would you say that it doesn't matter if I change the voltage or the amps when trying to be as energy efficient as possible?

1:52 in the background there is a noise of what appears to be a 3D printer :)

[@EsamoKoram]

Nice one! For a flywheel too!

[@davidprock904]

Ludic Science , Maybe you can help me, how do I balance out all factors (and what factors) so I can have an electromagnet under a continuous dead short indefinitely, stay powerful and constant with out getting to warm. Being safe!

[@lez7875]

saudações do Brasil a todos. inicio do vídeo pensei: é um truque!!! mas o Incrível Beakman dizia que na ciência não há truques. então entendi que tudo é magnetismo, equilíbrio e electromagnetismo. muito bom.o aparelho pode ser usado como um magnetômetro??? parabéns. sucesso.

[@ludicscience]

Its a goog idea to use it as magnetometer

[@lez7875]

@@ludicscience . Yesss!!! I made a useful suggestion. success.

[@igrewold]

Great stuff man :) Thanks

[@ludicscience]

😊

[@ricomajestic]

Nice motor you got there. So how many windings in that coil and what is the strength and dimensions of those magnets?

[@ludicscience]

Around 500 turns, it is not critical. Magnets are also not critical

[@jonatanvillagran3253]

So you can basically power it with a lemon or a cup of salted water

[@ludicscience]

Yes

[@E_tronics96]

Hi again-just got idea-how'about making an electrostatic motor with this idea

[@ludicscience]

I think its a good idea

[@EsamoKoram]

I like how it jumps :D

[@Edmorbus]

Thank you

[@ziadfawzi]

Thank you.

[@anshkunwarji987]

Plz make high voltage for Tesla coil .

[@oqueedeuseoquechamadodeus5346]

muito legal

[@buildpune699]

Wow..

[@edersonsimplis5127]

🍮☕

[@trench01]

Its not balanced.

[@ludicscience]

It is attracted by the earth magnetic field like a compass

[@davemwangi05]

Trench, who cares?
