Analysis of High-Resistance Connection Fault of Permanent Magnet Synchronous Motor

High-resistance connection fault (HRC) is a common and typical electrical fault of permanent magnet synchronous motor (PMSM). At present, there are few analyses of high-resistance connection fault. Therefore, this article is based on ANSYS simulation software and analyzes different levels of high-resistance connection faults of permanent magnet synchronous motors in terms of current, magnetic field, electromagnetic force, vibration and temperature field. And this article provides sufficient theoretical basis for the diagnosis of high-resistance connection faults of permanent magnet synchronous motors.
