Hello
I need a motor that can run at between 120 to 150 rpm, doesnt have to be able to change speed.
It has to be quite low noised and at atleast 5 watt power.
I found this on ebay:
That one would seem to do it. But don't forget it is brushless so would need a driver. Fron that standpoint a brushed motor would be easier, but also noisier.
