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,

Check out ESU they are selling three different Hamo Magnets
For Marklin Locos.
One of them will fit your BR 141
The Part# for Drumtype Armature ESU Magnet is 51962 Marklin Part# 235690.
This according to the Marklin Spare Parts List however check your Engine
if it is A SCFM ARMATURE the Part# from ESU is 51961 Marklin Part# 220450.

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

Yes, it would be nice to know wich of the three offered by ESU fits on what motor.
I'm willing to make a conversion of a DCM engine soon..... |

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.  |

Ray, I think this should be clear enough... DCMMarklin spare: 235690 ESU equivalent: ESU 51962 For rotor 231440 (3-pole DCM), inner diameter 18mm  SFCMMärklin spare: 220450 ESU equivalent: ESU 51961 For rotor 200680 (3-pole SFCM), inner diameter 18mm  LFCMMärklin spare: 220560 ESU equivalent: ESU 51960 For rotor 217450 (3-pole LFCM), inner diameter 24,5mm  |

Wow!
Thanks Juhan, that is clear.
Now all I have to do is confirm the type of motor...

The LFCM has a bigger diameter than the other two, so that should be easy to find out.
How about DCM/SFCM, how can you tell the difference ?
I should get a nice old 3000 one of the next days, which should be converted to digital someday - so i'd like to know.

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?

Ahh, now i understand it :)
It's good with some pictures of the rotor to explain everything..
Thanks a lot

Yes, but the loco that i want to convert is a crocodile with a five pole engine already, so the hamo magnet should be enough to convert that loco.

<br />Yes, but the loco that i want to convert is a crocodile with a five pole engine already, so the hamo magnet should be enough to convert that loco. 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. Regards, Lutz

In Esu website you can find the list for the conversion of all marklin locos, with indications about loksound and conversion difficulty. Try: http://www.loksound.de/index.php?showId=175 This is for #30XXX locos, click the list in the left of the page for other series. Bye

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. |

To be honest, the 3556 needs a conversion kit a la 60901... The 610030 anchor has lower resistance/impedance than the normal 3-pole DCM and also the 6090x anchor, and is not really usable for hamo conversions as I see it since it will draw a lot of current from the decoder. Maybe Lutz has some experience with this...
Even if it was an attempt from Märklin to get a smoother running motor for analog models - honestly the 35xx 5-pole motor sucks... I have 3 locos that were originally fitted with this motor and they were the worst pullers ever, even if they ran very smoothly on their own without any load...
A sidenote....
On the other hand, not all 35xx are bad, the analog 3511/3513/3514 Württemberger C is one of the smoothest & powerful locos for analog drive, but these have Faulhabers onboard with electronic voltage regulation, not that awful 5-pole motor... They instead sucked in their digital 36xx/37xx variants until the 37113 came around with a real "cruise control" decoder that has the performance comparable of, or maybe even slightly better than the analog 35xx models of this lok... |

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. |

MMMMh, thanks Juhan, so it seems i will have to buy another 60901 kit, it may have been good to save the one i have for my BR 53, but........ |

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.  Regards, Lutz 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.
