The Electric Spindle Built-in Motor Thermal Equilibrium Active Temperature Control Model

Abstract:

Based on the structure characteristics of electric spindle built-in motor and numerical heat transfer theory,electric spindle built-in motor physical heat conduction model was given and a mathematical temperature control model for the electric spindle built-in motor was established. According to the mathematical temperature control model, controllable factors for the heat balance was determined. By electric spindle own screw channels, using this mathematical temperature control model to adjust the flow speed and fluid medium temperature, the built-in motor quickly reached heat balance and maintained temperature field stability in the electric spindle start-stop and using process. Then the theoretical calculations and simulation on the electric spindle built-in motor was conducted.This model is designed to enhance high-speed precision spindle machining accuracy and the use of performance.Nomenclature:
