The present invention relates to an electric driving tractor and, more specifically, to an agricultural torque support system of an electric driving tractor motor capable of improving the performance of an electric driving tractor in a soil environment in which a slip occurs, in other words, a situation when there is difficulty in escaping from a rough area due to a decrease in the rotation speed of a motor and a drop in the output of the motor in case of a motor slip. The agricultural torque support system of an electric driving tractor motor includes: a main driving motor (M1) driving a PTO shaft connected with a working machine while driving an electric driving tractor; and a sub driving motor (M2) driving a hydraulic pump connected with a hydraulic system of the working machine, or driving the electric driving tractor. The sub driving motor (M2) supports torque only for a rear axle of the electric driving tractor when the electric driving tractor has a slip rate (S) of no less than a predetermined speed.

    본 발명은, 본 발명은, 전기구동 트랙터에 있어서, 모터 슬립이 발생하는 경우에 모터의 회전 속도가 줄어들고, 동시에 모터의 출력이 낮아지게 되어 험지 탈출이 어렵게 되는 경우에, 즉 슬립이 발생하는 토양 환경에서 전기구동 트랙터의 성능 향상을 위한, 전기구동 트랙터 모터의 농작업 토크 지원 시스템에 관한 것으로, 전기구동 트랙터를 구동하면서 작업기와 연결되는 PTO축을 구동하는 메인 구동 모터(M1)와, 작업기의 유압시스템에 연결된 유압펌프를 구동하거나, 전기구동 트랙터를 구동하는 보조 구동 모터(M2)를 가지며, 상기 보조 구동 모터(M2)는 상기 전기구동 트랙터가 일정 속도 이상의 슬립률(S)을 갖는 경우에, 전기구동 트랙터의 후차축에만 토크를 지원하는 것을 특징으로 하는, 전기구동 트랙터 모터의 농작업 토크 지원 시스템에 관한 것이다.
