Abstract: This paper introduces the classification of magnetic loss fault and the characteristic curves of permanent magnet materials, analyzes the causes of magnetic loss, classifies and compares the existing magnetic loss fault detection at home and abroad, studies the detection of loss of excitation fault from different angles based on parameter identification. Finally, the prospect of magnetic loss fault detection is prospected.

Key words: permanent magnet synchronous motor, demagnetization, fault detection, machine fault, control strategy
