Compatibility. Servo motor sizing spreadsheet is tested on Microsoft Excel 2007, 2010, 2013 and 365 for Windows. Microsoft Excel for Mac is currently not compatible.
By substituting equations 3. and 4. (torque and speed, section 2.1) into equation 2. (power, section 1.3 ), we see that the power curves for a D.C. motor with respect to both speed and torque are quadratics, as shown in equations 5. and 6. From these equations, we again find that maximum output power occurs at = ½, and = ½ repectively.
