Answering this question would improve the thread a lot since the noload current is used to estimate iron losses.I can say that some things were interesting in this thread, one example was noload current between two powervelocity controllers was something like 50% higher with the same motor. Was that measurement correct, based on dc volts * dc amps and measured with a good DMM?
If so, then one of these controllers is a crappy match for the tested motor and this is (if correct) interesting. It then makes all noload testing become questionable as well as the quality of the controller.
The large efforts to add extra bell reinforcements are not needed if there’s a really tight grip fit to the shaft like in my two RV120pro motors. It is hard to move even with a three jaw puller.
It would be good for others to know how this is for the different motors, and all the other basic data, presented as a table.
You know, all data:
verified noload currents@2 voltages &stated rpms
Wye or delta
grip or no grip fit shaft to bell
Copper fill factor where you have this.
Since the overall quality is so poor then the motors can be considered as diy stator-rotor kits for the happy motor winder - they might be OK for this use, at least for the 0.3mm lamination ones..
