Cheap motor source

[Ember]

Wouldn't have expected to find an S-can in a toothbrush. Why can't I ever find such useful things at the tightwad shop?

Which "Dollar Store" chain?

[TsgtRet]

Plus you get another toothbrush to use for all those slot related things we use them for! I'll try and stop by our Dollar Tree tomorrow and see if they have those.

Thanks for the tip !
I love the brand "Luminant" wonder if it started out as Ruminant.
Need good teeth to chew on that for a while :lol:

Thanks for the tip! picked one up & installed it in one of my Carrera super birds. The motor seems to run ok & turns decent rpm at the axle, checking my stock motor it got 5840 best rpm at 9 volts (using my hand held rpm meter), with the dollar motor we got 6670 best rpm hmmm, after 50 plus laps motor still seems ok but felt a little warm. One thing I found is this motor only fit my Carrera inline set up car & not my sidewinder Scally cars due to the short end can drive set up, we will see how long it runs this sat nite in hard compettion with many more laps & much more abuse.

We tore this dollar motor apart last nite just for kicks & to check it out,, found the brushes are very small & not much to them. We have Carrera mtr. brushes to put in if it lays down on us :o . We also cut 2 small 3/16 holes in the mtr. case on top to help it with the cooling issue. Sure sounds good & turns some decent RPM for a buck with a brush :lol: . Will keep you posted...

What an awesome thread!
I stopped by our local Dollar Tree (after I mistakenly stopped into Dollar General first and couldn't find one for less than $5.50) and picked up 5 of them to play with! I have a couple Womp chassis without motors that I picked up cheap as part of an auction lot that I am going to use as a test bed for these to see how they do. There isn't currently a class at my local speedway that I participate in that I will be able to use these motors in - but for the price, I just couldn't resist and had to try them out!
I figure if they work well in that application, they may find their way into a scratch build or two down the line!

LOL! - Wonder if these couldn't be used for the next round of Mini Proxy racing? Price is definitely reasonable enough! :D
(might be a bit much motor for that - but could prove fairly entertaining!)

Hmmm - wonder if once the brush material is gone, if it will run on the copper "springs"? (or Dave - are you saying it "quit" after ten minutes?)
Not sure if you have had one of those SL-1 motors apart - but I tore one down that I screwed up when I was learning how to properly get both a sleeve and gear pressed onto the shaft without shoving the front bushing in. (yes - learned a lesson there)
Those motors have "no" brushes at all - but rather they just have little copper "fingers" that ride on the commutator. Not sure how the longevity of those motors compares (might be better since they are lower rpm?) - but would be interesting to see if these toothbrush motors don't continue to run even once the brush material is gone?
(again assuming that after ten minutes, the motor didn't just quite - but instead was still running - just didn't have any brush material left?)

[TuscoTodd]

Interesting that it "smoked" but that the other is still kicking...
Maybe the quality control is a little looser on these than a normal slot car motor (considering the application?) - or maybe like you said, the one was just a dude that possibly had a rough commutator that ate the brushes, or a bad brush material or? Will be interesting to see how long your "second" one lasts. :)
I plan to get two of them broke in this weekend for use in the Womp cars and assuming they survive a wet break in - I'll make it a point to run the weeds out of them at the next run to the track. :)

OH - and yeah, I "wish" I didn't get to find out what the inside of the M/T SL-1 looked like... But in thinking about the Scalextric motors - with a bright light on the endbell, you can see the brushes through the little holes - so I will have to see how close these appear to those this weekend. (doubt I will be able to get a picture - but will try) :)

Quick update, ran somewhat ok after last nites thrashing got real warm after 20 or so laps on a big 120' oval. Stuck better brushes in it but it was pretty much cooked, motor at the beginning of the nite lacked torque then just slowed down & died :whistle: cooled it off did the above things to it but that was it. Stuck the 'ol 21,500 slot.it motor back in & was back in biz. We at least have a tooth brush to clean parts or give it away for a Christmas present :lol:

[TuscoTodd]

Thanks for the update!
I, unfortunately, can't seem to figure out where my pinion puller has disappeared to off the bench (I'm sure it is close enough to bite me!) - so I haven't had a chance to do my wet break in on the batch I have. Was going to see if they lived/liked that and if so, then two of them are getting mounted in womps to test/abuse on the next trip up to the local track.
HOPEFULLY my puller comes out of hiding today and I can give you guys an update from my end as well.
:)

Well, if the puller doesn't show it's face tonight, I am resorting to the 1/16" punch to get the counter weight off there and will be putting these five through a wet break in to see how they do.
More to follow - hopefully later on tonight! :)

How many batteries go in the toothbrush? One thing I've found is that 3 volt motors (two AA's) run really fast at 12 volts, but obviously don't last.
