Let's try a different question.
Here are the specs for the 2014 BAG motor:
Spec Voltage: Vspec = 12
Spec Free Speed: Wfree = 1466 radians/sec
Spec Free Current: Ifree = 1.8 A
Spec Stall Torque: Tstall = 0.403 Nm
Spec Stall Current: Istall = 41 A
Calculate Ke and Kt from the above data, and discuss possible reasons why these values are not equal.
