制造装备用定子励磁混合磁路直线旋转永磁电机及其解耦控制技术研究

Considering the requirements, including fast response, strong load capacity, wide operating frequency range and etc., for the linear and rotary drive system of manufacturing equipment, a novel stator excitation hybrid magnetic circuit linear and rotary permanent magnet (SEHMC-LRPM) motor is proposed. The motor with double salient topology is consist of one stator and one mover, which exhibits the advantages of simple and compact structure. The torque/inertia ratio and the dynamic response speed of the machine is greatly improved because of the lightweight and strong structure of the mover. In addition, owing to the design of stator excitation structure and the hybrid magnetic circuit in axial and radial direction, the speed-regulation range of the motor in linear, rotary and spiral operating modes is broadened while keeping the improvement of the torque, thrust, and power density. The project aims to study the basic operation principle, the accurate calculation of the parameters, design theory, the electromagnetic characteristics, and optimization design method. The coupling mechanism of the linear and rotary magnetic field in the hybrid magnetic circuit will be analyzed, and the decoupling control strategies will be studied under the different operation conditions to realize the stable and reliable multi-mode operation. Hence, the key technique problems of the SEHMC-LRPM motor such as the design and optimization of the machine, the decoupling and coordination control of the two degree of freedom drive will be resolved. The general laws of the motor including the design, analysis, and control are explored. The scientific questions are put forward, which will lay the theoretical basis foundation and technical support for the future study and application of the SEHMC-LRPM motor in the drive system of intelligent manufacturing equipment. Therefore, the investigation of this project has important theoretical significance and practical application aspects.
