    Default Atlas N Scale DC electric motors

    Hi guys..

    I understand that over the years Atlas has made some different versions of the motors that they have used in their N scale trains..

    Does anyone know is this is true, and if so, does anyone have a timeline for when they were used, and also know how to tell the difference between the different models?

    I recently had a motor fail in one of my Atlas SD35 locomotives.. Basically it looks like two of the five windings on the armature has gone short circuit..

    I have just received the replacement motor for this train, and it has a black plastic end shield (where the brushes are), but the old motor out of the SD35 has a grey end shield.. The new motor is supposedly for or from an SD35, and both motors have 5 pole armatures..

    Just wondering if they are different model motors..

    Cheers

    Mark.

    PS.. Tried using the search function, but as per most forums, it returned zero results..

    Yes there is huge differences in the motors used in Atlas Locos. Fast Speed, Slow Speed, and Scale Speed. The gray end bell motors are all scale speed motors, the only difference in these motors are the flywheels and contacts. You can use a black end bell motor in your loco but it will run faster.

    Thats not what I wanted to hear..

    Oh well, I hope I can do some tuning with the decoder to get them to run the same..

    OK,

    I just fitted the new motor to my Atlas SD35.. Not only are these "black" motors faster than the grey ones, they are also 5X louder.. It makes my older LifeLike Locomotives seem quiet...

    This thing sounds like a lawn mower.... lol.. Hopefully it will quiten down a bit after it has run in some..

    Looks like Im in the market for another new motor.... lol.

    I'd double check your work. That doesn't sound right. (no pun intended)

    You might want to call Atlas and explain that the new motor doesn't match the old one. They might exchange motors for you.

    I have no experience with N-scale in this regard, but in HO, about the only thing better than Atlas motors are Kato motors. The way N scale locomotives are built, with the frame that just about totally encases the motor, I would expect a lot of difficulty using a motor that wasn't designed for the chasis.

    Hi Arved..

    I'm quite sure that everything is OK in regard to how I installed the motor..

    The noise is no different to the motor noise I get from my LifeLike locomotives, or even my old Bachmann Spectrum 8-40CW, just a lot louder..

    What made the noise seem worse is that I was running (in) a brand new Atlas SD35 at the same time, and the new SD35 is almost silent...

    I will send an email to Atlas and see how I go..
