I have two same sized DC brushed motors found in different variants of an appliance of the same brand. They are possibly equivalent, but they have different labels.
One is labelled with:
(Johnson Electric logo) 31348 3K3861
The other is labelled with:
3501-0011-01 REV C CIM-2450-1 24 VDC 0.9 A 50 RPM /15 LB-IN 9-95
The diameter of the motors are 27.5mm, and length of the motor bodies is 32.5mm.
What does the last line, beginning with "
50 RPM" mean? Surely it doesn't simply mean the nominal speed, since 50 RPM is way too slow. Does it have something to do with the concept of "motor regulation"? This online catalog meantions motor regulation in units that I am not sure about, e.g. on page 50, for motor model HC313G-001, it says
Motor Regulations: 304.857 Rpm/m-Nm . Huh, is that
rpm per millinewton-metre?
