Analysis oil the Thermal Characteristics of the Spindle with High Frequency Motor according to the Cooling Methods

고주파 모터 내장형 주축의 냉각에 따른 열특성 해석

Thermal characteristics according to the cooling methods are studied for the three type spindles with high frequency motor. For the analysis, three dimensional mode]s are built considering heat transfer characteristics such as natural and force convection coefficients. Unsteady-state temperature distributions and thermal deformations according to the cooling conditions are analyzed by using the finite element method.
