Abstract
Ceramic motorized spindle is a multifield, nonlinear, and strong coupling system. The present model ignores the reverse magnetic effect and has a poor accuracy on the loss of the spindle system. In the paper, Park transformation was used to establish the electromagnetic physical model of ceramic motorized spindle. By combining with the Jiles–Atherton theory, an eccentric magnetization model of a ceramic motorized spindle considering reverse magnetic properties was established. Energy consumption parameters were calculated under various working conditions. The influence of ceramic reverse magnetic characteristics on the motorized spindle loss was analyzed and verified by experiments. The results show that the simulation of the ceramic motorized spindle loss model is in good agreement with the experimental results. Compared with the experimental results, the average loss error was 2.1%. Due to the reverse magnetic characteristics, the application of ceramic motorized spindle can help reduce the system loss. The ceramic motorized spindle model provides a theoretical basis for the development of ceramic spindle energy loss and efficiency.

Summary
As the core component of computerized numerical control (CNC) machine tools, the high-speed motorized spindle has a complex coupling system. Energy development and management are crucial to further improve the machining efficiency of motorized spindles in high-speed operation [4, 5]. Some researchers [14,15,16] proposed a dynamic adjustable induction motor (AIM) considering the rotor skin effect on current, which improved the energy efficiency of the manufacturing process. Many researchers [20,21,22,23] proposed some new energy-saving management, which can enhance efficiency through optimizing the motor current and torque, but the research studies did not involve a better fit for the ceramic spindle in some special cases. E loss model of the ceramic motorized spindle is studied, revealing the relationship between reverse magnetic, harmonics, and loss. A ceramic motorized spindle is of great significance to improve the energy output performance and reduce loss in extreme environments
