  I tried a number of different 'dampening' materials but did not get the noise down to a level that I was willing to tolerate. My solution was to replace the Premotec motor with a Maxon (2140.937) and a small homegrown DC regulator (standard application of a LT1086). I made me a PCB that fits like the original inside the original motor housing (can) and a small pulley. The only mod to the original housing is a wider hole in the top cover to accomodate the Maxon (plus two smaller holes for fixing the motor to the cover). The result is a very quiet motor can with good performance (no noticeable speed variations when checking with a 300Hz strobe) and also pretty stability over longer time (days/weeks).
  Regards, Andreas

    Replacing the motor is a bit more drastic than I had hoped :) but thanks for the suggestion.

    I've applied the tweaks Brian suggested (and further used some automotive / vehicle dampening material to line the inside of the motor). The noise certainly has been reduced, but it still louder than "dead quiet".

    I'll live with for a while and see if I get used to it. I suspect I will. If not, I may find myself down a similar path you've taken :)

    Thanks again,
