With ElectroCraft, the whole part number is important. The main model
number just defines the frame the motor is built on. I don't have the
E-543 in my book, but I do have the E-542. There are 4 versions,
denominated -01 through -04. The torque constant and voltage
constant are different for all of these motors.

I did find some info on a goldmine web page :

but these are not very useful measurements.
