Desempenho de microtrator operando com diferentes fontes alternativas de energia.

Abstract

In this work, the acting of a microtrator was evaluated used in the coffee growing implemented with three different types of motors. A same chassis of a microtrator was worked, alternately, with a motor electric trifásic (MCA), a motor tramway of continuous current (MCC) and with a motor of internal combustion (MCI). In the front part of the microtrator two accessories were coupled with the purpose of turning over the fruits of coffee in sewage yard. Rehearsals were accomplished to evaluate the acting of the traction bar and to determine the capacity of field of the microtrator working with the revolvedores. In the rehearsal accomplished for the rehearsal in the traction bar it was set up in factorial outline 5 x 2, five skating (5, 10, 15, 20 and 25%) and the two exchange marches (1st and 2nd march), in delineament entirely casualizado, with three repetitions. In the determination of the field capacity the delineament was used casualizado entirely, with four repetitions. It is ended that.
