Motor power calculation from torque and speed
Nettet24. mar. 2024 · Welcome to Design World’s “How to Calculate” series … where you learn how to apply the most important equations for sizing, selecting, and comparing linear motion and motion … NettetPower = voltage x current. Since (assuming negligible controller loss) input and output power are equal, as output voltage is lowered so output current must increase by the same ratio. Motor current can be derived from Kt, rpm, and efficiency. 6034W in x 81% = 4888W out, or 61 N.m x 769rpm.
