Evening boys.

I've just taken delivery of a tray of 'mabuchi style' motors that I picked up very cheaply on everyone's favourite auction site. Here's the listing. Now, while they're good value at $35 for the tray of 50 and most of my creations powered by these motors will only ever run on my track against similarly powered cars, I would be curious to see some tests run on them to see what sort of performance can be expected.

Is there anyone out there who would care to run some tests to find out?

I'm really not expecting much from them. At 70 cents per motor, who would? But I figure any car that shows any kind of promise can always receive an upgraded motor.

Cheers

These motors look the same as some I tested for a friend recently, all around 13,000 rpm @12 volts. BUT the ones I tested did not have any carbon on the brushes when I pulled one apart.
I also test some that were around $6.00 each and they had the same speed but had carbon brushes. The advantage of carbon brushes is that they last O/K on 12 volts!

I emailed Mabuchi about these. Not sure if I still have the email. About NC1, maybe a little less. 10-12k and 35gcm of torque but dont quote me on that. Might make for a good rally motor.

Phil do you think they will be the same as the dick smith motors? Do the Dick smith motors have brushes? Ive got a few dick smith powered cars & I quite like that motor

They're most likely to be going in classic cars. I figured anything is a bonus. Anything that turns out well can always get a motor upgrade at a later date. But I just can't justify $18 - 28 to power every kit experiment at the moment.

Sorry theyre not the ones I was thinking they were. That seller was from Wingfield. Seriously they could be absolutely anything. Lucky dip really. The specs he lists dont correspond to what he has and he hasnt listed the full specs. Its missing the 5 or 6 digit number at the end. The "D" in the motor means its a special customer spec and who knoes what the customer wanted these motors to do??

FC130SD YYXXX

F = flat design
C = carbon brushes
1 = Armature diameter
3 = magnet size
0 = 3 pole motor
S = anisotropic magnet
D = customer spec
YY = wire diameter
XXX = number of turns on windings

As they say in the classics, Are ya feeling lucky punk?? Well are ya??

And so we go back to the original question. Anyone want to run some tests for me? Thinking it's more for the benefit of others on the forum to know whether or not they're worth the bother.

Yell and I can fling you a couple to test to destruction (or otherwise) for the good of mankind.

im happy to put a motor to test on my track

Hey Ember,
Plucka at WSMCR has an engine dyno. Maybe he could do you a bulk deal.

[Ember]

Thanks Bulsara.

Surely one has the right to expect that being of the same 'specs' or I suppose more correctly 'batch' they should be within a certain tolerance. Will send Plucka a PM and see what he has to say about running some tests.

Basically, I don't care about the performance on the whole. They'll be running against themselves. I just thought it might be useful to see if they were possibly a useful budget buy for anyone else. Obviously wrong on that score. Never mind.

i will get 4 emb's

[Ember]

Ok. I've still got your postal address Obsid. I'll pop a couple your way. You're more likely to push them than I am. And if you win any proxies with them I'll take 5% of the credit.

I was really hoping someone might be interested in benchmarking them. If there's a slim chance of them being a good buy others might be interested.

well i have a few different motors i will track test them back to back like i did with the t/a cars

[kalbfellp]

Greg: the old DSE motors did not have brushes BUT the later ones seem to. I ude the DSE motors and fitted them with Scalex brushes.

[chilla]

Hi Embs
Thanks for the heads up
I can check the RPM but not the torque
You should be able to strip one down to check the brushes
Probably just as easy to substituting one for a scaley car and run it for a seat-of-pants assessment
I agree with you, they'd be ideal for powering kits. You've got close to a lifetime's supply of standard spec motors so every new car you build can be compared to the others.

Cheers

Just noticed they're can-end drive so not a direct replacement for scaley. Might be just the thing to repower a Revell to get some brakes happening though.
Happy to test one in a Revell Greenwood Corvette.

I wouldn't be much help in testing them Emb, don't know a lot of that technical stuff.
I have spotted bulk lots like that on eBay and wondered if they were suitable for slot cars. As I feel the same as you - hard to justify $20-30 to put a motor into a kit car just for the fun of it. I bought a couple of little Tamiya motors to see how they would go but they are only rated at 3v so was worried they would burn out at 12v...

I am keen to know how they go - they say 1-15v so that is promising, I will be following this thread and see what folks come up with.

cheers

be keen to hear how that goes - tis a beast isn't it... big fat tyres no brakes...

[Ember]

Don't have anything quite ready to drop one into on hand at the moment, but I might be able to rig something up to get one on the track tomorrow.

I don't have any Revells on the shelf Chilla. Well, I fib on that but both the Roller and the Auto Union are still on their sprues. Might be able to drop one in the MJK based Corvette that's about to be painted.

Thanks to those who are interested in giving them a whirl for a more educated opinion. PMs on the way.

If they are canend drive they will drop straight into a carrera or artin. I dont know much tech stuff Embs but I sure am interested in how these motors to see how they go. Best I could do is run one on track side by side with other similar motored cars. Ive got some cars with the DSE motors, artin motors, NC1 motors & BWA which I think would have similar performance.
