I got this motor off ebay and thought it was the same size as what I have in my 2-6-8-0 (see photos ) ,but it is smaller. It has the same brush mount as the Mantua stock motor, but is 7 poles compare to the stock 5 pole motor. Can any one give me some specs on the new motor? I have a flywheel that I think could work. The engine runs good, but I would like to improve the crawl. My Mantua 2-6-6-2 with the newer stock can motor with flywheel has worse crawl then this older open frame motor.
If you want to improve the slow speed you would be better with a can motor not an open frame unit, unless it is heavily reduced in gearing but does not appear to be to me.
Thanks . I do have the stock mantua can motor from the last release logger but it is very small and in my 2-6-6-2 its crawl is not as good as the 2-6-8-0. To be more specific the crawl on my engine is good but not smooth at very slow speeds ( tends to stall ) I had hoped a fly wheel would help this. Also the pickup is only one side of each driver set and one side on each truck. I wanted to used Walthers tender truck from the USRA 0-6-0 ,they have all wheel pick up but the are not available.
Mantua's small motors could be a three pole skewed armature motor. The 7 pole motor will run better than a 3 or 5 pole motor, eventually if it a brand new motor, as the bearings haven't been "run in", and brushes worn to better sit on the comuntator.
Thank you for your responses . I think I will try the 7 pole motor. It looks to have the right mounting hole on the frame . One thing is with the extended gear cover for the fourth driver I have to remove this cover to access the motor screw and need to be careful not to crack the JB weld holding it together.
bigger is usually better in terms of motors, trying to use a small motor for a big loco (also big locos tend to pull bigger trains) and will wear out quicker. I'd suggest minimum 22mm diameter can motor for that loco, bigger if possible. A good quality can motor shouldn't need a flywheel, can be beneficial in some cases and on DC. Generally speaking the more poles the better the motor. Good luck.
