Max power is right at half the maximum RPM on these DC motors. Power is Torque x RPM. In the attached picture, power is "inside the box" if you will. At any other point on the chart, the resulting box will be rectangular and thus have less area (less power). Maximum efficiency is at somewhat higher RPM. Ideally, you want to have the motor working at somewhere between 20% to 50% of maximum torque to keep the motor happy.

[Ken, are you still using globe motors soaked in liquid hydrogen? ]
