Ke = 81.7 V/krpm measured
or
Ke = 81.7*60/(1000*2*pi) = 0.78 V/rad/sec
Kt = (3/2)^.5 * Ke = (3/2)^.5 *.78 = 0.955 Nm/Apk
or
Kt = (0.955 Nm/pk)*1.414 = 1.35 Nm/Arms
The the internal setting of our Voltech power analyzer measurements was incorrect. So now the voltage and current measurements are in question.
Plan to retest in a few weeks.
