Homopolar Motor With Emergency Brake System

The World's Simplest Electric Motor, the homopolar motor, can occasionally overheat or fly apart during over-enthusiastic experimentation.

This is an effort to counteract that out of control situation, by means of a simple governor device. When the device senses either vibration or overspeed, it shuts off the power and applies the drum brake to bring the system to a safe stop.

You can buy neodymium magnets where I do,

Holy shit. Automatic Breaking System? ABS?

or did you just mean a piece of bent wire?

[MrfixitRick]

@Gunner3210

Automotive ABS systems are all about "bent wire". The magnetic speed sensors are made of a bent copper wire coil that a magnet passes over. The brake system computer with a bunch of bent wires inside controls the pressure into the brake lines, which moderates the braking action.

I have simply replaced the ABS CPU with a tin can ;)

[Gunner3210]

@MrfixitRick You are mistaken. Modern ABS systems use hall effect sensors which are actually made of composite of semiconductor crystals. I assure, there has been considerable effort, research and technology that goes into producing these sensors. These sensors are extremely reliable and accurate.

Even the older coil pickups you are talking about are very much more reliable than your bent wire. As a demo, it's fine. But it is a far stretch to call it a "Emergency Brake System".

@Gunner3210

I guess this means my dream to be a millionaire by selling this design to the auto sector is out??

[Zoidberg227]

Is that a neodymium sphere holding the whole apparatus to the stand? And do you use rechargeable batteries?

[MrfixitRick]

@Zoidberg227

Yes and yes.

1:37-1:40 look closely at the right side of the lower magnet and you will see a small spark.

How did the chillies taste after this?

thanks for share...

OLD EL PASO! xD

[AgentRikuOfficial]

@NaderX77 lol

no prob

[NaderX77]

@AgentRikuOfficial actually it was just a bad joke

but i didn't know that homo means same so thanks

[AgentRikuOfficial]

@NaderX77 homo sexual and homo polar are 2 different things. homo just means same.

[Gunner3210]

@safc44 Thanks for telling me something I already knew. I know exactly what ABS really means. If you watch the video again, you will notice that the poster calls it "automatic braking system". I just sarcastically called it ABS.

[safc44]

@Gunner3210 ABS does not usually stand for "Automatic Breaking System", it actually stands for Anti-lock Braking System. Just to let you know

Any relation to Steven Wright?
