Homopolar Motor With Five Speed Auto Shift

Latest development of the five speed homopolar motor... automatic shifting. Watch it go faster and faster as it goes through the gears by itself !

The homopolar motor consists of a magnetic disc, a battery and a conductor, and is the simplest form of electric motor.

The homopolar electric motor design is also the most efficient, powerful and quiet form of motive force, and is being used for the newest Naval vessels.

For Homopolar Motor Kits, with 3 magnets and 6 feet of copper wire, order from the good folks at the American Stirling Engine website: http://www.stirlingengine.com/ecommerce/product.tcl?usca_p=t&product_id=93

I order from the best selection of neodymium super-magnets at:

where do yu get the magnets

[MrfixitRick]

@polarawesome

I get neodymium magnets online from K&J Magnetics. (link in the "Show more" box). Other sources are a craft store or hardware store. Or find a shake-type flashlight and tear it apart.

That's pretty cool. Do you think the conductivity of the different coins is the effect or the distance from the the brush to the magnet.?

[MrfixitRick]

@Dragonfire7666

I think multi-speed effect is mostly because of the radial distance, that is, from the centre of the disc, to the brush that is acting as commutator. The larger diameter disc will rotate slower when considering the same surface speed between the conductor and the disc surface.

do the coins have to be magnetic?

[MrfixitRick]

@jakedjo

The coins don't have to be magnetic, but they will stick to the magnet easier if they are. You could use a magnetic steel washer to hold up some non-magnetic coins perhaps. Or glue the coins on. Or simply use different sized magnetic washers instead of the coins.

@doggie1kitten

Judging by your channel, "boring" seems to be the only comment that you leave for others.

[MrfixitRick]

@Adelbert1309

Basically, the wire conducts a current which forms a magnetic field that reacts with the magnetic field of the magnet.

The principle is the Lorentz force (see wikipedia under Lorentz Force and homopolar generator and homopolar motor.)

Everything begins at 1:00

[thegizmoguy1]

Now make it downshift haha.

[Dragonfire7666]

@MrfixitRick

Oh.. So it's more concerning the electron flow K=distance.

I like how it floats down the control. Almost like it has a combination with nature. I believe that's a secret of this device yet to be told.

[CBsParanormalSociety]

and what can you do with this?

[Zainiak]

Manual FTW!!!
