Hornby TT:120 Gresley Pacific, Coreless motor kit install, testing and data

#hornby #hornbyrailways #modelrailwaylayout

BDD-Ltd whom many of you will know as Richard of #This Way works fame has been busy tinkering again and a while back asked me to test and give feedback on a coreless motor project he was working on as a direct replacement for the BE N20 motor fitted as OE by Hornby on the Gresley Pacifics and the 08 shunter.
This is the prototype motor being fitted, tested and a conclusion, it works and very well!
Kit includes a large size premium quality coreless motor with nylon worm gear pre fitted at correct spacing for the Hornby TT:120 Gresley Pacifics. Two specific motor spacers to enable the motor to sit perfectly aligned with no chassis modification required or glueing of motor cases. The large size motor manages heat dissipation exceptionally well, often an issue for coreless motor designs.
The motor has been subject to 29 hours of running, some sessions of 90 mins, 10 heavy coaches (mine have battery illumination which at 12 will stretch the KK system!
The loco has been tested with lots of stop/start running and seasons of 60 minutes in reverse over a range of speeds. While the gearing drops the potential top speed from the OE model, that is too fast, the scale speed calculator confirms a loaded is capable of a scale 101mph. The motor has continued to run better as the hours have ticked by.
Link to the complete kit, as always I have no financial affiliation with any many or supplier, I am 100% independent hence the request from Richard to test and see what happens.

A useful link to the HM DCC and 7000 manual. It’s a very good system that makes a whole range of adjustments very easy and none of the dark art nonsense.
