van door torque curve

anyone have the specs on the van door motor? I am trying to find a graph of the torque curve if it even exists

Here are the specs (all at 12 Volts) from past years:

Van Door Motor (Tiagene): 75 RPM No Load Speed, Stall Torque 37 Nm Clockwise, 34 Nm Counter-Clockwise, Stall Current 40 Amps.

That’s everything you need (except no-load current, which is probably a couple tenths of an amp) to plot the torque, current, power and efficiency curves.
