摘　　要：为了解决大倾角带式输送机在启动和制动阶段由于加速度过大易引起物料滑落、动张力过大易导致输送带撕裂这一难题,基于直接转矩控制提出了大倾角带式输送机变频调速控制方法。实际应用表明,基于DTC的大倾角带式输送机控制模式转矩响应迅速、低频时转矩输出高,启动后转矩上升平稳,在各种装料条件下,均能确保物料在35°倾角的带式输送机上稳定输送。In order to solve the problem that material downward sliding occurred by the start speeding too higher of high inclination belt conveyor and the conveyor belt tearing easy occurred by the higher tension. A motor speed control method of high inclined belt conveyor was put forward based on direct torque control. Actual application shows that the big dip Angle belt conveyor based on DTC control mode torque quick response, low frequency high torque output, smooth torque increased after the start,under various loading conditions, it can ensure that the material in 35 ° inclination of the stable conveying belt conveyor.
