Solid diamonds and the cards below show the required project operating points. Hollow circles and callouts show available torque at each selected speed, with its required voltage. With positive torque limited by voltage, the point lies on the supply line. A zero-torque point may lie above the supply line if back-EMF already exceeds the voltage budget. Green and blue diagonal hatching distinguishes overlapping available-torque bounds. These rectangles are not complete feasible regions: a point must also lie on or above its speed curve and respect current and torque caps.

Torque vs. FFBeast Power Limit

Theoretical torque based on the torque constant and configured current scale. Temperature and magnetic saturation are not modeled.
