Verfahren und Vorrichtung für die dreidimensionale magnetische Formgebung eines Motorkerns

摘要

A method of forming a cylindrical magnetic motor core having predetermined magnetic properties includes recording a 3D geometrical model, translating the geometry of the model into control parameters, and positioning magnetic material within a staging area surrounded by independently-controllable magnetic field generators. The control parameters are transmitted to the field generators to generate 3D magnetic fields, which are controlled to magnetically shape the material into a motor core substantially conforming to the model. After shaping, the core may be solidified to form a finished core. A system for forming the magnetic motor core includes a host computer controlling the position and motion of each field generator. The 3D model is used by the host computer to control the magnetic field generators and shape the MR material into the magnetic motor core.
