Homemade Brushless Motor (reed switch motor)

[xRandomBEASTx]

where can i get a reed switch

not burlgler alarm or website

[mozon1967]

@xRandomBEASTx - Good question... Try a hardware store for some cheap alarm equipment.

[Henry92RLC]

@slanderousndgs No it hasn't. Perpetual motion machines are impossible to make.

[cyborgtroy]

@Henry92RLC - You can make them, they just won't run.

[kevinraymorrison]

@Henry92RLC Do some research on John Bedini if thats what you think. It's VERY possible, might need an outside source to start it, but it is perpetual.

[llorencaguiar]

Would this motor still work if you used six magnets on the drum?

[mozon1967]

@llorencaguiar - I'm sure it would, but you may need a bigger drum.

awesome



[cjoss07]

heaps cool video thanks

[heberorozco]

omg omg! excelent!

[jauchiu]

Very nice video. Very educational. Thanks for posting.

[vroom350]

Very nice! but one thing transistor with metal for heatsink but not work for help cool down, better use aluminum more help cool down and more life.

Hi

Where can I find reed switch which does not get burnt ?

I am making electromagnet which needs to be on/off by fast rotating magnet. Power supply is 12V car battery. Any comments are appreciated.Thanks Charlie

Very Cool!

this is to all comments (sorry i couldn't reply to all)

simply a reed switch consists of to prongs in side when a magnet is near these prongs touch (or get pulled together)

so every time the magnet on the drum passes over to reed switch it will trigger and let a sudden amount of electricity go into the electromagnet

the electromagnet attracts a magnet on the opposite side then quickly turns off giving the drum a little push to make the quarter turn

this happens very quickly

very simple

[clarosse]

Awesome

[Corp0ralPunishment]

Cool!

[insanity54]

I see a magnet from a security system sensor!

[cow4awife]

This project is proving to be a real pain in the ass!, I would appreciate any help I can get on it, any little secrets you got there. Thanks for sharing looks good

[diverdanaccount]

NIce!

[horizonflyer9]

I need to make this motor!

[emo4eva2000]

what kind of magnets are those? neo?!

[xmind22]

I'm still confused..Coz I'm new to this stuff.

Would you please reply..

[xmind22]

I think I understood the working of this motor But Is is really necessary to use the reed switch? Why? Could you please explain it to me.?

[crack1110]

whats the speed 10000rpm or what lolz

[acalthu]

i've been using high powered brushless motors from mega and medusa research in my radio controlled cars since the beginning of this year. now i know how they work!!

[rcwor1d]

great job man im proud!

[bamabanshee1]

holy crap!! that's cool. CAUTION WATCH FOR FLYING MAGNETS !!!!!!!!!! LOL

[goekfoke]

Did you have any problems with replacing the reed switch? It seems pretty fragile.

[Bigfurry1975]

Great job on a DIY brushless motor, The RPM's are pretty decent too. I wonder what kinda torque that has

[mozon1967]

The torque is very low.

[cueballxp]

im new to this and is there anyway to time it insted of a reed switch thanks

[faackoof]

@cueballxp triple 5 timer switch?

[wirelesscps]

wht is a reed switch

[mozon1967]

This motor used a small burglar alarm contact that has a reed switch in it. A reed switch is a tiny vacume sealed glass tube with metal strips inside that react to magnets.

[VideyoJunkei]

radio shack sells them (?) alarm systems still use them for door open/close sensors-check a hardware store.

[67Cowboy]

What is it? What is it for? What is it doing (spinning)?

[mozon1967]

This is a model electric pulse motor, also known as a reed switch motor or brushless motor. Just a model made as a hobby.

[67Cowboy]

What is it ? What is it for? What is it doing (spinning magnets ?) ???

[dodoshlodo]

its a motor!

[kaspardlov]

where can you buy a reed switch?

[mozon1967]

Used to find them in Radio shack. Try on line electronics suplly.

[SilverKey7]

I didn't know the reed switch can connect-disconnect that fast!!!! did you use any special kind?

[mozon1967]

I didn't know either. No special kind

needed

[SilverKey7]

btw, you dont need to use the transistor, the reed switch can support upto 400milliapms, which is enough to drive that coil

[mozon1967]

Thanks for the comments. I believe that the transistor is there to protect the switch from the back emf spikes comming from the coil. The switch will last longer disconnected from the coil. Thanks again. Maurice

[gargara]

yes but now u have to explain or i will say it is a fake.

[mozon1967]

I don't know what you meen..? The video explains how it works.

[kubikop]

Nice, Like it...

[mozon1967]

Thanks for commenting.

[laphant]

perhaps the mags are superglued on...??

the reed switch is in the base circuit of the transistor or the emitter collector ?

[mozon1967]

The magnets are screwed on to the plastic drum...if you look close you can see them. Sorry I don't remember about the transistor, I'd have to find my printout. Originally found the design on the web..."Brushless Motor" or something like that.

Maurice

[laphant]

thats a nice little motor..how to make the little coil please,tractorum..there are tiny ball bearing races available from dead disc drives..i wonder if it would run up the rpms to be on tiny ball race?tractorum

[mozon1967]

Thanks for your comment. The coil is nothing special, prehaps 30 turns of 24 awg wire.

Not much resistance from the needle /drum setup but bearings couldn't hurt I guess.

Maurice

[laphant]

the axle for the magnet drum...is it simply a plastic vial with holes punched in the ends for the axle?,,

[mozon1967]

It's a long sewing needle punched through the drum.

[jdhall82]

Cool, very simple.

[flagtube]

Isn't that a Bedini-Like motor? Then you can put a flywile on the axes and reload the battery with it by putting an alternator on the exes.

[mozon1967]

No, not a Bedini.

[mozon1967]

I found the design on the internet.

[Opinaca]

Nice for teaching purpose ;)....like, smart science for kids!

[bornman88]

Very smart!
