Hi Guys,

I would like to convert a 3037 Br141 to digital using a lokpilot decoder and a Hamo magnet.

Does anyone know the part number for the Hamo magnet?

Presumably it depends on the type of motor, which I think is a SFCM.

Any help would be appreciated.

Ta,

Ray

Thanks Martin,

The 3037 I am getting is an early one in a picture box, so I think it more likely to be a SFCM. However, I won't know until I receive it and open it up!

I'm curious how you know which ESU magnet fits which motor? I couldn't find out from the ESU website, which is why I asked the forum.

Thanks again,

Ray

If you can find your Lok on the conversion list for a 6090X kit, you can tell what magnet to use.
I just order the motor kit (without decoder) to do Lokpilot/Loksound conversions. Your favorite dealer should be able to get the parts for you.

Wow!

Thanks Juhan, that is clear.

Now all I have to do is confirm the type of motor...

The DCM is a drum commutator motor which has two carbon brushes facing towards each other, pressing on the commutator from opposite sides.

The SFCM has a flat commutator and both brushes face the same way. Also one of the brushes is carbon and the other is copper mesh (I think).

I don't think I've explained it very well. Does anyone have pictures of the different motor types?

Is there something wrong with this one?

Execpt the terminology, I know it's called brushes....

[:I][:I][:I][:I]:Nothing at all!Never thought of it though [B)]

Kind regards

If a croc has a 5-pole engine, it's either a digital model with DCM motor which has already a permanent magnet (usually indicated by 37xxx product numbers) or it's an analog model with a 5-pole 19mm anchor (#610030, not yet contained in Juhan's list) - a quite rare case due to the usual higher speed of that motor - instead of the standard 3-pole anchor; again both are DCM motors. Only for those one you'd need a HAMO Magnet (#235690).

If you talk about the famous 3015 croc, that's a completely different story.

Thanks Lutz, no it is not the 3015,
It is a 3556, with an analog engine, an electronic reverse unit, and a 5 pole rotor.
Thanks for the info.

Beware when using this list.

It seems to quote the latest type of motor fitted to each locomotive. It could be wrong if your model is an earlier type.

For example, in the case of a 3037, it assumes that the motor is a DCM, but if the model is from before the 1970's it will have a SFCM.

Best to physically check your model before ordering.

Juhan, I fully agree!

The 600030 5-pole anchor mounted in a HAMO magnet draws about 3 times more current than the 3-pole with the same magnet or a 60901. In one of my test setups (gear from new BR212) the 19mm 5-pole draws between 170-450 mA (max 950, with "blocked wheels"), whereas the latter two one consume 100-170mA; max. 300-400mA.

Due to the lower strength of the magnet + the anchor, the rotating force (-> pulling power) is substantial less than that of a 60901.

Agreed, with little or no load, they run somewhat smoother - but if you'd compare with a 6090 decoder, this is again different.

Although ESU supports this (mainly due to lower cost since only the magnet is needed), I am as well not in favour of this motor type. It was anyways only delivered in 35xx models with a special designed electronic circuit ("7180") and in pure DC (HAMO) models. 38xx/83xx.

For todays digital operation, the 6090x has clearly a much better performance. Go for it!!! [:p]

My "old" 3656 also runs perfect with a 60901; to make some use of the functions supplied by this decoder, I've replaced the bulbs with the LED light from the 3956x and added the Swiss light pcb (which allows to switch from "white" to red) and direction dependent cabin lights. You might just need to rework the magnet in order to properly mount the center body onto the frame.

PS: I've as well "upgraded" my marvellous Württ. C (3611) to the Decoder of the K; besides the cruise control this also allows now to switch the smoke unit.
