The interest in surface mounted permanent magnet synchronous machines with concentrated windings (cwSPMSM) is increasing owing to their lower winding cost and the feasibility of more compact designs than the traditional ones with distributed windings. The elimination of mechanical sensors for rotor position measurement makes these drives even more competitive. Sensorless control of this machine type has got extensively attentions due to their promising properties. For the in series produced cwSPMSM, however, the sensorless control method has not yet been studied. This is because, firstly, they do not present significant magnetic saliencies, on which the traditional sensorless technologies using high-frequency signal injection are based; secondly, such machines show strong multiple saliencies, which cause large torque ripples using traditional sensorless control technologies; and thirdly, the saliency does not show constant properties with different excitation frequencies, for which no specific study has been carried out yet. The proposed study will provide a solution to this problem based on the sensorless concept by injecting revolving high frequency signals into the machine. As the starting point, a composition method will be realized, which removes the influence of the high order saliencies using the decoupling technology. On this basis, a combination method will be implemented, which, as the focus of this proposal, makes use of the information contained in different orders of the saliencies, in order to achieve increased accuracy. As a further step to extract even more information about the flux position, a multi-frequency injection method will be investigated based on the dependency of the saliency properties on different frequencies. In addition, the initial position detection for starting the machine from standstill will be also included in this study. Finally, based on the successful implementation of the proposed methods, the sensorless control of cwSPMSM in the full speed range will be realized combining with the traditional method based on back electromotive force.The results of this project will not only be directly applied on the studied machine type, but also provide new ideas and possibilities for the sensorless control of all kinds of machines with multiple saliencies.

集中绕组表面安装式永磁同步电机（cwSPMSM）由于其较低的绕组成本和比传统的分布绕组更紧凑的设计的可行性而越来越受到人们的关注。消除了用于转子位置测量的机械传感器，使这些驱动器更具竞争力。无传感器控制由于其良好的性能而受到广泛的关注。然而，对于连续生产的连续SPMSM，无传感器控制方法尚未被研究。这是因为，首先，它们不存在显著的磁凸极，而使用高频信号注入的传统无传感器技术是基于该磁凸极的;其次，这种电机显示出强烈的多个凸极，这会导致使用传统无传感器控制技术的大的转矩脉动;第三，在不同的激励频率下，显著性并不表现出恒定的特性，对此还没有进行具体的研究。拟议的研究将提供一个解决这个问题的无传感器的概念的基础上注入旋转的高频信号到机器。作为出发点，将实现一种合成方法，该方法使用解耦技术去除高阶凸极的影响。在此基础上，将实施一种组合方法，该方法作为本建议的重点，利用显著性的不同顺序中包含的信息，以实现更高的准确性。作为提取更多关于通量位置的信息的进一步步骤，将基于凸极特性对不同频率的依赖性来研究多频率注入方法。此外，本研究还包括从静止状态启动机器的初始位置检测。最后，在上述方法成功实现的基础上，结合传统的基于反电动势的无位置传感器控制方法，实现了连续永磁同步电动机全速度范围内的无位置传感器控制，本课题的研究成果不仅可以直接应用于所研究的电机类型，而且为各种多凸极电机的无位置传感器控制提供了新的思路和可能。
