I would vote for Mashima 1830D. It has 16% more peak power and 36% more nominal operating power. The mystery is at what RPM - load does the motor no longer sustain operation. 1830D is likely poorer because it has a higher nominal operating speed. The bottom three motors are way to fast if the Mashimas are right. They would have to have 2 to 3 times the range. I'd have to see a map to understand if they can make it.
Donnell I haven't forgotten your request. I am looking for some actual map info to be able to help discuss it.
If I have a loose Mashima motor, how do I tell what the model number is? I actually have three, but other than a plate with Mashima written on it, I can't see any model info. The ones above are a different length, the rest of the data is all the same. If that is the case, mine are 1824D's.

Hi Larry,
The 18 is the width in millimeters across the flat sides of the motor, and the 24, 30, or 33 is the length of the motor casing.
I did order one each of the three Nichibo motors pictured at the bottom. A few years ago I had some custom hex flywheels made for a bunch of Igarashi motors I purchased on eBay. I will equip the Nichibo motors with the flywheels and install the assembly in an Athearn chassis for testing. My gut tells me that they may run a bit fast, and for passenger units that may be okay.

Donnell, Sounds like a good plan to me. Hopefully you can bounce them off a stock Athearn motor of some type for comparison.
I also have a couple of NWSL motors. I will check out who made the motor and if there is any specs available.
Like you, I'm looking for some background info for a motor variation set of tests. I'm starting to think I should Bose a DOE approach..
