Hi Everyone,

I'm wondering if there is a difference between motors in 36xxx and 37xxx locomotives. I haven't purchase a new 37xxx series engine for quite some time, I think the last one must have been around 2006 otherwise any locomotive I've purchased since that time has a sinus motor. I was unaware until I received my newest engine (37127) that Marklin has moved to mainly a can motor/drive shaft setup. I naturally expected it to be super quiet and run like butter but that is not the case, what I did find is that at certain speeds it growls as much as my 36xxx engines so this got me to wondering, am I paying a lot of money for a 37xxx engine which is very detailed on the outside but has the same technology under the hood as a 36xxx engine?

Thanks

Mike

I had a feeling that would be the answer, the other thing that made me suspicious of this is the paint job, I noticed on the 37127 the paint is more of a matte finish and somewhat coarse while my older engines are smooth and glossy.

Is it possible to upgrade the motor if you want or are you pretty well stuck with what's in there?

Thanks

Mike

A beginner question.
What are these motors that you are talking about? What are the differences?
I know the old motors in the analogue engines (e.g. 3003, 3025) that had 3 poles then there were the motors with 5 poles but I have no idea about the rest that were mentioned (Google didn't help).

Thanks

Ben

Here are the old Marklin motors and Faulhaber:

C-Sine motors (Marklin only):

With the C-sine motors you have the older 'big' style C-sine and the newer compact C-sine motor.
The big C-sine is not very common and its decoder cannot be changed as there are no new decoders that can run the motor.
The compact C-sine had some issues with power sensitivity and had a driver board upgrade, whereby it was renamed Softdrive C-sine - the most common.
Compact C-sine locomotives could be returned to Marklin for this upgrade, so there are not many compact C-sine locos left either.

There are also other various motor types, all DC motors and all typically quiet and run well - such as Faulhaber and Maxon but many more which are not named.

This company provides upgrade kits for a large range of models to Faulhaber/Maxon motors:

Note that the cause of significant noise in many models is actually the transmission and not the motor. Hence why modellbau also provide transmission upgrades.

Marklins numbering initially assigned the 39XXX series to C-sine locomotives but this is no longer the case, you will find 39XXX models with other DC motor types and some 37XXX models with C-sine.

I don't think Marklin are releasing new models with anything less than a quiet DC motor, so it's of little concern now.

In recent years there have still been some issued with DCM motors (coffee grinder) because they were still using old moulds.
With the release of the new BR44 chassis I don't think there are any more, except maybe the BR78.
I am not sure about the new Marklin 37068, BR80. Previously it had a DCM motor but maybe the new one has a motor upgrade - the brochure does not say.

Here's a little more info on the Sine drive, from 2007 - hard to believe 12 years ago already.....
