Fever is one of the most important factors affecting the dynamic performance of the spindle, and it has a serious impact on the processing precision of the electric spindle and prolong the service life of the machine tool. By analyzing the power source of the electric spindle, the related factors that affect the temperature rise characteristic are found out. Using ANSYS finite element analysis software, motorized spindle temperature field is analyzed, and the temperature rise of thermal deformation simulation provide the basis for the further development of thermal error compensation scheme. Aiming at the problems of difficultly measuring the internal temperature of the electric spindle, a temperature prediction model is established and experimental study is carried out by infrared thermometry. The results show that the method can effectively set up the early warning mechanism, can realize the prediction of the in
