I have data for the E-703 motor. It has 4 possible winding patterns,
specified
by a dash number.

dash Kt Ke R, Ohms L, mH Ipeak
-01 24.5 18.1 .26 1.1 83
-02 49 36.2 .79 4.4 42.5
-03 78 57.7 1.94 13.7 30
-04 113 83.5 4.21 28.4 21

Units of Kt are Oz-In/Amp, Ke are Volts/KRPM
Max continuous torque is 410 Oz-In

I don't have any data on the 713.
