I am hoping @Norton or @harmonyards can help me with this. I see different steam engine upgrades documented on the forum using 12V Pittman motors. Given that we typically operate at a higher voltage than that, and fixed voltage systems from mth and lionel run at 18 or in some cases 20 volts, how are these motors not burning up? I am used to industrial equipment and if I put 600 volts in a 480 volt motor for an extended time it would run until the insulation fails and be scrap soon after.
Also, what is the typical rpm of these motors? I am still playing with my lego steam locomotive idea drive train and the lego motors are rated for 9 or 12 volts, and the speed is less than 300 rpm so they need to be geared up considerably to get a decent operating speed.
