S-Can/Short Can Motors - BAracer - 20th-Nov-20

Just getting into motors...

I noticed that Pendle have separate categories for S-Can and Short Can motors.

I can see that S-Cans perhaps all have a separate plastic end bell, whereas Short Can motors seem to be enclosed within a metal case. But I cannot believe there are separate categories just based on the design of the case.

Are there fundamental differences between these two motor types?

Dont want to hijack the thread but more along lines of adding to it. AM looking forward to the knowledgeable people answering your question as I too am interested.

In another thread Grah mentioned motors from China. I decided to give them a try.

They arrived in SIX days and for a change - no duty or post office charges - so for 60 odd Euros I got these 26 motors:

Not tested them as yet but one thing I can tell you is that the magnetism shown by these motors, far FAR outweighs anything bought locally - so I am expecting big things from them. You will al;so note I chose the ones that extend both sides of the motor so can be used in more applications.

the strongest magnets there btw are in the HO look alike motors

Hello Jeremy,
"S-Can" is not a manufacturers designation, it came into common use after Scalextric started using that type of motor. No idea of why. The "Short Can" designation refers to motors that are the same construction as "Long Can" but are shorter.

i've just had a batch of the yellow endbell s cans to test and I find they are on par with the best of my nc1s running at 13500 rpm at 12v . and at 99p each well worth a punt . The ones I have are shaft from the can only as nc1. Down side may be they are not carbon brush type so I cant say how long they might last on the plus side the magnetic field is stronger than the Nc 1 . They do loose out to the 12k short cans I reviewed by about the length of a car over 3mtrs .
I also recieved a 26d size designated an fc260 this runs at about 27 k and has carbon brushes also can drive . It may be an option to get some vintage chassis mobile as 26ds are now a bit rare .

They aren't interchangeable in most chassis / motor pods, which is almost certainly whey Pendles have kept them apart - "that motor you sold me doesn't fit!". My very limited experience of the Short Can is from the latter-day Ninco NC9 'Sprinter' motor. I think some of the MSC cars have them too?

Despite the design being different (outside and inside), I suspect the rpm and torque stats are going to tell the tale of how they perform - the Scaleauto S-Can and Short Cans seem similar from the data on the Pendles website - but that's not to say some of the characteristics won't be different, like magnetic downforce maybe?

It is fun picking up cheap sub-£1 motors from China. I got some long-cans a while back that looked and performed like they were from a batch of Avant Slot motors. I have some of the yellow end-bell S-Cans with the metal brushes that are a bit rough, to say the least! Plus some white-can carbon-brush ones that are pretty smooth, come out about 23k rpm, but are a bit gutless torque-wise. Also found some lovely lower-rev replacements for the Scalextric FF motors. All great for home use, but probably a false economy for competition?

So fit rather than different inner architecture...?

RE: S-Can/Short Can Motors - woodcote - 20th-Nov-20

The components are almost identical, but the inner architecture is slightly different - mostly to do with the brushes. Depending on the specs of the important components - magnets & armature - the performance will be similar. There are a lot of variables (magnet size & strength, ohmage of the armature, wire gauge, commutator timing, brush material, brush tension etc.) that give specific characteristics to any motor, so I suspect the difference in the can design will be another factor.

In short, the 'S-Can' is an FC130 motor and has its brushes and springs fixed in the plastic 'endbell' which attaches to the half-metal 'can'. The 'Short Can' - or FK130 - has slightly different gubbins inside a fully-metal can. Most 'Long Cans' are FK180 motors - same set up, but longer.

If you have the full motor code of a Mabuchi motor, you can interpret it via this guide: https://www.mabuchi-motor.com/product/knowledge/classification/designations.html

That can be useful on eBay or Alibaba etc.

Thanks.

Got it.

I got a handful of those clone orange Hurricane motors too.
Wish I'd grabbed more. Really decent motors of similar performance to the nsr king purple.
Very worth grabbing despite the short spindle which made inline setup a little more problematic.

The Chinese Avant offloads are easy to spot because Avant have most of their cans painted instead of wrapped.
Now, if anyone spots any Republic motors (pink) , Sprint motors (red) or Hunter motors (white / black) being off-loaded, please message me !

Hi Andy,

I don't suppose you have a link to the lower rev Scalextric FF motors you managed to get hold of ?

Some of the modern GT3 cars just rev like crazy, and would be so much nicer if they were comparable to a standard Scalextric Mabuchi.

Many thanks,
Pip
