WebInduction Motor Speed Torque Characteristics Typically, when a NEMA Design B induction motor is started across-the-line, an inrush current of 600 to 800% FLA occurs, corresponding to the starting torque point. As the load is accelerated to the full-load torque point, the current decreases to 100% full-load current at 100% full-load torque.
