“…ERMANENT magnet synchronous machines (PMSMs) manifest superior advantages of high efficiency, high torque density and fast dynamics, and thus been widely applied to modern civil and industrial equipment. Since the PMSMs are mostly supplied from pulse-width modulation (PWM) controlled inverters [1], there exists large amounts of time harmonics inside the motor components which will generate eddy-current and hysteresis losses. Once overloaded, the elevated temperature rises introduced by the losses may cause accelerated aging of the winding insulation [2], diminish the magnetic properties of the PMs [3], and limit the torque output.…”

“…Therefore, estimation of stator resistance is even more critical in DTC synchronous motors than in DTC induction motors. Accurate stator resistance estimation is also important in thermal monitoring and management of synchronous motors to achieve optimal operating point or to prevent overheating [13], [14]. Several methods are proposed in the literature to track stator resistance variations in DTC synchronous motors.…”
