In electric drive systems, a necessary condition to ensure that the drive system can operate at a constant speed is that the motor’s torque T be equal to the load torque TZ of the driven machinery. A. Equal in magnitude and same direction B. Equal in magnitude but opposite directions C. T is greater than TZ, and they have opposite directions D. T is greater than TZ, and they have the same direction B
B. Equal in magnitude, opposite in direction
