“…For salient-pole synchronous motors, the direct asynchronous start-up or reactor start-up procedure is customarily realized. The startup procedure requires the proper sequence of actions according to the current state of the drive [3,5,9,13,21,22]. An unsuccessful start-up can lead to fixing a motor work at sub-synchronous speed, long-term operation with current greater than the rated value, electromagnetic torque pulsation, and speed oscillation resulting in significant mechanical overload on the motor shaft and early wear of the bearings.…”
