Study on Steady-State Temperature Field and Thermal Deformation for Permanent Magnet Synchronous Motorized Spindle

Abstract:

Motorized spindle thermal deformation is a major factor affecting the accuracy of high-speed machine tool, previous studies have focused on asynchronous motorized spindle, however, in this paper, permanent magnet synchronous motorized spindle is the research object. At first, the finite element model of thermal characteristics of motorized spindle is established base on its thermal characteristics analysis. The second, study on the distribution of the spindle steady-state temperature field, effect of spindle speed and bearing lubrication on thermal deformation of spindle. The results provide a strong theoretical basis for the design and use of spindle.
