This is a XBD Coreless motor with a 4 mm shaft and it  is 35 mm (Diameter) and 40 mm long.  Sleeving available to go upor down with the shaft size and length. .


It has ball bearings  which makes it coast through dirty track work and see pictures the armature becomes a flywheel because there is no iron core!! No  torque ripple at slow speeds. It just keeps pn chugging.  The torque of most O and G scale sized motors is subject to torque ripple and cogging and if you het a dead spot it stalls!! And because its coreless then it has half the stall amps due to its high efficiency.  So you can work with smaller amp load decoders which are less expensive.


It has ball bearings and  will coast several  seconds no load because it has 9 poles and there is zero cogging in a coreless architecture.  Put two locos and do a little cornfield meet with one having an iron core motor and the other the coreless motor and see which one slips the wheels first!!


It will coast a lot longer than an iron core as there is no cogging when the power is interrupted.


If you like your locomotive to start like the prototype and chug smoothly through rough track and deadspots this is the motor for you!   I have many customers who have tried them and love them due to the high power.  The lack of an iron core (coreless motor)  means zero cogging and when power is interrupted it coasts and does not stall!


Because of their efficiency these motors  will not load down on hill or under heavy loads and your pack will deliver more volts for speed (high amp motors eat up your volts eating up your speed!!) Volts and amps vary inversely under load!


Efficiency is rated over 75% converting Amps to stall torque!!
