Methods of resistance estimation in permanent magnet synchronous motors for real-time thermal management [PDF]

, 2010
Real-time thermal management of electrical ma- chines relies on sufficiently accurate indicators of internal tem- perature. One indicator of temperature in a permanent-magnet synchronous motor (PMSM) is the stator winding resistance.
