Papers by Keyword: Built-In Spindle

Abstract: In this paper，the characteristics of GD-II built-in motorized spindle is introduced；the thermal features of the frameless motor and the hybrid bearings have been studied；the 2D temperature field model has also been developed by finite element method．The results of the calculation show that a good efficiency of heat transferring has been achieved with the oil-air lubrication and oil-water heat exchanger．
