摘　　要：在电力电子系统集成的基础上,提出了一种能够实现电机端电压和电流、转子位置和速度、磁通和转矩检测的概念性集成传感器模块,讨论了利用凸极跟踪方法实现转子位置自检测的原理。实验表明,这种传感器集成方式能在永磁同步电机全速范围(包括零速和极低转速)准确地观测出转子的位置和速度,实现了位置/速度传感器与电机本体的集成。以此为基础设计出的概念性的集成传感器模块可配合集成化的电力变换模块,方便、简洁和可拓展地构成高性能的电力电子传动应用系统。Based on the power electronic system integration,a novel conceptive sensor integration module is suggested in this paper,which is capable of detecting motor voltages and currents,rotor position and speed,fluxes and torque.Moreover,the principle of rotor position self-sensing based on saliency-tracking technology is discussed and the experimental investigation manifests that the proposed saliency-tracking scheme could be used in the whole speed region, including zero speed,to estimate the rotor position precisely,and implement the integration of the position / speed sensor combined with the motor.The hardware structure and inside functions of the conceptive sensor module are designed, which can be combined with other integrated power electronic modules to form a high performance power electronic drive system conveniently, compactly and extendably.
