Check out our 04/08/2019 Blog for a 12 Volt DC 15 x 20 x 32mm motor we recently tested and found to be acceptable for remotoring projects. http://cwrailman.com/blog/12-volt-15-x-20-x-32mm-motor-review

Did you ever test the motor from your last post?

Thanks for asking.
Yes, they finally arrived and our tests of these motors was not as favorable as we would have liked. They produce a better than average amount of torque right from the start however they do not start rotating until around 3 volts which is 1 volt higher than our preferred start speed and their slow start speed which is around 800 RPM leaves a bit to be desired. We are a bit turned off by the 1.5 mm output shaft. If space is critical and you are replacing an open frame motor, this motor will work, especially if you are using DCC and can adjust the operational characteristics, such as the "kick start" CV a bit to get the motor to start at less than 3 volts. However, it would not be our first choice if the 15 x 20 x 30-32mm or 15 x 20 x 25mm lower RPM motors will fit. We do see it as a good fit for some locomotives with restrictive boiler height configurations such as the PFM Long Bell Prairie where we would normally use a Sagami 1630 motor which has not been produced for many years. We will be amending our original blog on those motors later today.

If you have any additional questions please feel free to contact me.
