Ok so I did so recalculating. The speed shown is the free speed at that torque. But here is what I get, can someone make sure my math is right.

Stall Torque (oz-in) Free Speed (RPM) Free Current (Amps) Stall Current (Amps)
Minibike 570.00 5310.00 2.70 133.00
Globe 3194.53 79.87 0.58 21.58
Nippon-Denso 1316.99 92.00 2.50 25.00
Keyang 1699.34 85.00 2.00 20.00
Banebots 125:1 4935 134.00 1.00 42.00
