© 2022 IEEE.This paper develops a survivability-based protection for three phase permanent magnet synchronous motor drives against severe dynamic events. The proposed protection is based on defining a survivability index ∗ PMsM that is expressed in terms of power changes resulting from a dynamic event, which is experi-enced by the protected motor drive. The index*PMSM establishes an accurate measure to detect, identify, and respond to dynamic events that a three phase permanent magnet synchronous motor drive may not survive. The validity, effectiveness, and accuracy of the survivability-based protection for three phase permanent magnet synchronous motor drives are assessed through simulation and experimental testing. Assessment tests are carried out using a 10hp laboratory three phase permanent magnet synchronous motor drive under various dynamic events. Assessment results demonstrate the efficacy and responsiveness of the survivability-based protection to unsurvivable dynamic events, and its ability to prevent damage to different components of a three phase permanent magnet synchronous motor drive.
