I see another problem to using one of the Maxon Coreless motors. (and possibly brushless). How to drive the things. I don't have any experience with the Brushless versions but I tried to drive a coreless Maxon with an LCRU and a DCRU and they did not play well together. The coreless motors when used with PWM need a much higher pulse frequency than any of the TMCC boards I have tried provide. I have not tried any Legacy driver boards. Has anyone tried driving a coreless motor with Legacy boards ? I have a dozen Maxon motors that are 44mm X 27mm and deliver about 50% more power than a Mabuchi 385 that is the same size. I would love to find a solution to using these with TMCC, Legacy or DCS. I know that the DCC manufacturers have addressed this problem so it can be done.
There is another possibility that I have been thinking about. Use two 385s stacked one on top of the other, or side by side, driving a spur gear on the worm gear shaft. You could play with the ratio between the motors and the spur gear to end up with virtually any final drive ratio you may want. The way Carl Tuveson modifies Flyer locos using a Spur and pinion gear with a Can motor gave me the idea. J
