The strong coupling among different parts such as bearings, seals, and windings, which are associated with different fields such as tribology, dynamics, and fluid dynamics, should be addressed to design a high-performance hydrostatic spindle. For decoupling and integrating all multisource information, the axiomatic design is using to address the design problems. A mapping with four levels of functional requirements and design parameters (DPs) was developed for the hydrostatic spindle design, and 19 DPs for the physical parts of the hydrostatic motorized spindle were integrated in several parts such as rotor, bearing, and winding. A 19×19 design matrix was built Using the design matrix, a flow chart for the dynamics design method coupled with multisource information was obtained. The design of a hydrostatic spindle was completed, and the major requirements were assessed. The results show that the dynamics design process and hydrostatic spindle can be optimized using the axiomatic design method.
