WebPower = 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. WebEfficiency can be expressed in simplest form as the ratio of the output power to the total input power or efficiency = output power/input power. For an electrically driven motor, …
