DC Motor Display

G'day,

I saw this motor kit at Jaycar (similar to radioshack) and thought it deserved a better case than the stand blue plastic one it comes with, also decided to spruce it up a bit.

Here's what it was:



Now the kit requires 3-6VDC to run, so i thought id install a regulator that i could vary the voltage hence the current, hence the torque hence the speed.

So i needed one kinda small that i could vary and could handle at least 2A and found this badboy:



I de-soldered the on board pot (10K) and soldered 3 wires in place that linked up to my external pot on the side of the enclosure so i could vary the voltage.

I put a 2.5mm DC power jack on the back so i could plug in one of my 12V PSU's.

Added a switch on the front to turn on the regulator, a red LED that illuminates when there is power available to the regulator and blue LED that illuminates when the regulator has power applied to it.

The brush arms that carry the current to the armature coils are insulated from the stainless case by 2 nylon washers then have a bolt running down the middle to the regulator underneath.

Now the kit came with a piss weak 3/4" cube magnet, so i replaced it with a 3/4" neodymium magnet which gives the motor sooo much more torque.

Here's some photos and a video of the motor running:






The motor runs pretty well on the regulator and controls the speeds pretty well, very pleased how it turned out

Thanks for looking!

Fiddy.

That's a neat Electric DC Motor display...:gj:

Do you really need to bang the enclosure onto
the desk to get it to start...:crackup::crackup:

Nice build. Good to see how an electromotor works. Next build be the miniature V12 engine.

Hehe thanks man. yeah it kind of gave it a kick start

Nice Job!
It looks like the box has wooden sides with a hewned edge, did you make the sides?
I hope that is how it is spelled

nah man, i bought it off eBay

Hey guys, guess what? i entered this into the Jaycar Makers competition and won 1 of 100 $100 vouchers!

See it here just passed halfway down: Jaycar Electronics - Makers

Pretty happy with myself right now

very nice should sell it haha

your very creative, i love your builds!

<3

Well done.

I love stuff like that.

thanks guys!

me to! i love electronics it's what got me into lasers!

Nice job Fiddy!

I Don't know why I didn't see this before, but a very professional looking build you've got there!

Maybe Jaycar can offer 2 DC motor display kits, the original, & a "High-end Pro kit" (yours). All while paying you huge amounts of money.

BTW - We're still waiting for the miniture V-12 engine that Blord suggested. LOL

:gj:

Bah, I saw that competition mentioned somewhere, wish I had've entered. $100 gift card woulda been mega handy last week when I needed some LM317's in a rush, and got ripped off with Jaycar's $2.50ea pricetag

Haha dam. I go there so often they put me under the local ammeuter radio club
