Online Detection and Classification of Rotor and Load Defects in PMSMs Based on Hall Sensor Measurements

Online monitoring and diagnostics of permanent magnet synchronous motors (PMSMs) is becoming important with the increasing demand in PMSM applications. Most of the research effort focuses on motor current signature analysis (MCSA) as it can provide remote, online monitoring at low cost. However, all...
