  • Frequency domain characterization of torque in tumbling

    Jan 01 2018 · By means of a flange type torque sensor the torque signal is recorded when the motor is driving a constant torque load (Fig. 1(a)) and a ball mill (Fig. 1(b)). The presence of an oscillating component of around ± 2 Nm superimposed to the average value can be observed in the case of constant torque load. Though expensive and less efficient the wound rotor motor and its adjustable torque-speed characteristics are great for driving large ball mills large presses variable speed pumps cranes hoists and other high inertial loads. They also are great for any application that desires smooth startup and the ability to change speeds.
