AI Technical Summary
Technical Problem
Existing brushless resolvers face issues with measurement accuracy due to magnetic interference between transformer and resolver windings, and they are difficult to manufacture and assemble efficiently in large quantities.
Method used
A modular resolver design with housing and hub elements made of different materials (non-magnetic and magnetic) to decouple transformer magnetic fields from resolver windings, using positive-locking, force-locking, and material-locking connections to prevent axial displacement, and shield windings from all sides.
Benefits of technology
Enhances measurement accuracy and allows for simplified, efficient manufacturing of resolvers in large quantities by minimizing magnetic interference and crosstalk.
