Cabinet Cooling Calculations

Use the motor’s speed torque curve to determine the torque when the motor
is at running speed for your application. If the torque is not known, use the
“knee” (where the peak-torque curve intersects the continuous-torque curve)
of the graphed motion—this assumes the worst-case scenario for continuous
motion.
