Abstract

Based on rotating magnetic coaxial effect of a suspended magnet rotor within the spatial universal rotating magnetic field(SURMF), a novel two-degree-of-freedom permanent magnet spherical motor (PMSM) and its lateral drive method using the rotating coaxial magnetic moment(RCMM) of the magnet rotor are proposed to address the complex electromagnetic driving structure, redundancy of control variables, complex coupled magnetic fields, and singularity of magnetic moments in current spherical motors. In terms of motor structure, the orthogonal kinematic decoupling and posture measuring of the PMSM output axis along yaw and pitch directions are realized by the universal follower mechanism (UFM) with a suspended magnet rotor. In terms of driving mechanism, with triaxial orthogonal combination coils (TOCC) as the stator, the orthogonal orientation decoupling control of the SURMF axis is adopted to realize the orthogonal decoupling of the RCMM in yaw and pitch directions, so as to realize the two-degree-of-freedom active drive of the PMSM by double decoupling of the magnetic moment and kinematics. For reducing magnetic moment orientation and motion path deviations caused by a slip angle, a compensation control method of the SURMF axis is proposed, which realizes the precise control of magnetic moment decoupling, ensures the precision and stability control of the motion path of the PMSM and lays a foundation for the application of the rotating coaxial driving theory of the PMSM.

期刊介绍： Mechatronics is the synergistic combination of precision mechanical engineering, electronic control and systems thinking in the design of products and manufacturing processes. It relates to the design of systems, devices and products aimed at achieving an optimal balance between basic mechanical structure and its overall control. The purpose of this journal is to provide rapid publication of topical papers featuring practical developments in mechatronics. It will cover a wide range of application areas including consumer product design, instrumentation, manufacturing methods, computer integration and process and device control, and will attract a readership from across the industrial and academic research spectrum. Particular importance will be attached to aspects of innovation in mechatronics design philosophy which illustrate the benefits obtainable by an a priori integration of functionality with embedded microprocessor control. A major item will be the design of machines, devices and systems possessing a degree of computer based intelligence. The journal seeks to publish research progress in this field with an emphasis on the applied rather than the theoretical. It will also serve the dual role of bringing greater recognition to this important area of engineering.
