We present the results obtained from the evaluation of electric center pivot machines produced by the company Otech-Irrimec. The evolution of the pump-motor assembly was performed as established by ABNT. Were measured engine power, the flow and pressure at the pump outlet. The pressure loss in the suction was determined using the Darcy-Weisbach gauge and pump load using the Bernoulli equation. Flow measurement was conducted using a flowmeter and pressure are determined by a pressure gauge at the outlet of the pump. Finally, the specific energy required by the components of the machine resulted in the order of 3,52 kWh / mm / ha.
