DSP-based 3D printed resolver-to-digital conversion system

This study compares a 3D printed resolver with a conventional resolver. The advantages of the 3D printed resolver are cheap, easy manufacture and modification. The equivalent circuit, transfer function, and Bode diagram of the resolver are presented and discussed. Furthermore, a digital signal processor (DSP)-based resolver-to-digital conversion system for 3D printed resolver and conventional resolver is built to validate the performances of the proposed scheme.
