NettetEngine power in kW can be calculated from engine displacement and crankshaft rpm. The formula for calculating the power of an engine is as follows:Ne = Vh * Pe * n / 120 (kW), where: Vh — engine volume, cm³. n — number of crankshaft revolutions per minute. Pe — mean effective pressure, MPa. Nettet21. jun. 2024 · We can use this number and our motor’s Kv to calculate the theoretical torque. Motor Kv is generally given in RPM/V, but for it to work in our formula we need it in SI units, which is (Radians/ Second)/ Volt in this case. To make the conversion we will divide 2300 by 60 s and multiply it by 2π. For a more precise explanation of motor Kv …
