WebPower input = Power output ÷ ηtotal. The average for axial piston pumps, ηtotal = 0.87. Furthermore, the power source (for example a diesel engine or an electric motor), must be capable of delivering at least 75 ÷ 0.87 = 86 [kW]. The hydraulic motors and cylinders that the pump supplies with hydraulic power also have efficiencies. WebAn electric motor runs with 3600 rpm with an measured power consumption of 2000 W. The torque created by the motor (without losses) can be calculated by rearranging (1) to. T = 30 P / (π n rpm) = 30 (2000 W) / (π (3600 rpm)) = 5.3 Nm. Torque Calculator.

WebBy taking the voltage and multiplying it by the associated current, the power can be determined. P = V * I where power (P) is in watts, voltage (V) is in volts and current (I) is in amperes A watt (W) is a unit of power defined as one Joule per second. For a DC source the calculation is simply the voltage times the current: W = V x A. WebEnergy conversion efficiency ( η) is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The input, as well as the useful output may be chemical, electric power, mechanical work, light (radiation), or heat. The resulting value, η (eta), ranges between 0 and 1. [1] [2] [3]
