提出了一种新型的内置式永磁电机驱动方法。在所提出的系统中，一个两相IPMM是从一个单相H桥逆变器低成本的应用。其d轴主绕组连接到逆变器，q轴辅助绕组固有短路。这种配置使电机能够在比大多数其他单相驱动系统更宽的速度范围内运行，并具有更高的能效。此外，尽管功率器件、驱动器和电流传感器减少，但其在高速范围内的扭矩能力与三相IPMM驱动器一样高。因此，所提出的系统具有诸如结构简单、成本低、功率密度高和效率提高的优点。本文采用等效三相电机对系统进行建模。基于该模型，分析了其转矩特性和工作区域，并与传统的IPMM驱动器进行了比较。还开发了速度控制算法。它包括一个最大转矩每安培控制，以提高驱动效率和弱磁控制，以最大限度地提高可行的逆变器输出电压。实验结果验证了所提出的系统和控制算法的正确性。
This paper proposes a novel drive method for interior permanent magnet machines (IPMMs). In the proposed system, a two-phase IPMM is fed from a single-phase H-bridge inverter for low-cost applications. Its main winding in d-axis is connected to the inverter and the auxiliary winding in q-axis is inherently short circuited. This configuration enables the motor to operate in a wider speed range with higher energy efficiency than most other single-phase drive systems. Also, its torque capability in the high-speed range is as high as that of the three-phase IPMM drive despite the reduced power devices, drivers, and current sensors. Accordingly, the proposed system has benefits such as simple structure, low cost, high-power density, and improved efficiency. In this paper, the system is modeled with an equivalent three-phase machine. Based on the model, its torque characteristics and operating areas are analyzed and compared to those of the conventional IPMM drives. A speed control algorithm is also developed. It includes a maximum torque per ampere control to improve drive efficiency and a flux-weakening control to maximize the feasible inverter output voltage. The proposed system and control algorithm are verified by experimental results.
