Analysis on the Cooling Characteristics of the Swindle with High Frequency Motor

고주파 모터 내장형 주축의 냉각특성 해석

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