koo9 Posted April 12, 2012 Share Posted April 12, 2012 Does anyone know what the typical current drain for a ringfield motor is please? Link to comment Share on other sites More sharing options...
Blackbird Posted April 13, 2012 Share Posted April 13, 2012 If you are considering using a ringfield motor for DCC operation, then it is the stall current that has to be addressed. There are several versions of ringfield motors, 3 and 5 pole versions. In reasonable condition they should be less than 1A. Most decoders will be useable, but it is advisable to test stall current on DC to confirm. Link to comment Share on other sites More sharing options...
koo9 Posted April 13, 2012 Author Share Posted April 13, 2012 Thanks, I was only after a ball-park figure and that is fine. I am trying to think ahead knowing the limited function current available. Link to comment Share on other sites More sharing options...
The son of Triangman Posted April 19, 2012 Share Posted April 19, 2012 Depends on age of motor, motor condition, type of ringfield motor as well.Early ringfields such as the one fitted to the Tri-ang-Hornby "Evening Star" were typically around 250ma when new and are listed as such in the 1971 catalouge. The norm for most ringfields is around 250-380ma in normal use, note this is not stall current which will be higher.You really need to do a stall current test to find out how much load a motor will be put under if the loco is BRIEFLY stopped (1 to 2 Seconds only) for some reason i.e. derailment etc., this will dictate along with function needs which decoder you need to fit.

Blackbird Posted April 21, 2012 Share Posted April 21, 2012 Most quality decoders will cope with a short circuit (max fault current) and shut down (trip)without damage, as will most controllers. Link to comment Share on other sites More sharing options...
