Abstract

We present the design of a saliency-based sensorless drive interior permanent magnet synchronous motor (IPMSM) for a traction drive in hybrid electric vehicles (HEVs), and we introduce the sensorless safety operation region (SSOR), which accounts for cross-coupling magnetic saturation and harmonics of inductance distributions. The SSOR defines a working point under the maximum torque per ampere (MTPA) trajectory in which the motor can perform sensorless operation with a guaranteed performance in the steady state. The reliability of the SSOR was verified by experiments using two prototypes. The influence of the IPM motor geometry on the SSOR was then examined. Consequently, the design guidelines were established to obtain a suitable motor geometry that can maximize the torque capability and the stability during the sensorless drive. Under the restricted specifications of dimensions and requirements, the 100 Nm-10 kW 12-pole, 18-slot IPMSM is optimally designed for the target traction drive in HEVs. The validity of the proposed design was verified using a MATLAB/SIMULINK-based dynamic simulator.

面向传感器的混合动力驱动专用集中绕组IPM电机设计

本文设计了一种用于混合动力汽车(hev)牵引驱动的基于显著性的无传感器驱动内部永磁同步电机(IPMSM)，并介绍了无传感器安全操作区域(SSOR)，该区域考虑了交叉耦合磁饱和和电感分布的谐波。SSOR在最大每安培扭矩(MTPA)轨迹下定义了一个工作点，在该工作点上，电机可以在无传感器的情况下运行，并在稳定状态下保证性能。通过两种样机的实验验证了该系统的可靠性。然后研究了IPM电机几何形状对SSOR的影响。因此，建立了设计准则，以获得合适的电机几何形状，可以在无传感器驱动期间最大限度地提高扭矩能力和稳定性。在尺寸和要求的限制下，100 Nm-10 kW 12极18槽IPMSM是针对混合动力汽车的目标牵引驱动而优化设计的。在基于MATLAB/ simulink的动态仿真平台上验证了该设计的有效性。
