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.
