This award supports research in high-performance precision motion control. One of the focuses is to establish the theoretical basis for the creation of an electromechanical spherical stepper capable of three degrees of orientation motion in a single joint. The ball-joint-like motor is based on the hybrid permanent magnet and variable reluctance principle and is characterized by simplicity of structure, compact design, absence of singularities (except at the boundary of the workspace, and lack of unbalanced rotor body forces. The proposed spherical stepper has significant applications such as high-speed plasma and laser cutting where the end-effector is required to orient quickly,l continuously, and isotropically in all directions. The development of the stepper presents a challenge in design, modeling, control and implementation. The initial support of the Presidential Young Investigator Award will permit the spherical stepper research to include experimental investigation and prototype development and evaluation.

该奖项支持高性能精密运动控制的研究。 重点之一是为创建能够在单个关节中进行三度定向运动的机电球形步进器奠定理论基础。 球关节电机基于混合永磁体和可变磁阻原理，具有结构简单、设计紧凑、无奇点（工作空间边界除外）和不存在不平衡转子体力的特点。所提出的球形步进器具有重要的应用，例如高速等离子和激光切割，其中末端执行器需要快速、连续地定向，并且 在所有方向上各向同性。 步进器的开发在设计、建模、控制和实现方面提出了挑战。 总统青年研究员奖的初步支持将使球形步进器研究包括实验研究以及原型开发和评估。
