Conclusions<br />
• <strong>Resolver</strong> Deserves More Attention for Applications where Rugged,<br />
High-accuracy Position Sensing is Needed<br />
• A <strong>System</strong>atic Approach is Necessary for Signal Generator /<br />
<strong>Resolver</strong> / Cable / <strong>Resolver</strong>-to-Digital Converter <strong>System</strong><br />
<strong>Optimization</strong><br />
• Simplore as a Multi-level / Multi-domain <strong>System</strong> Simulator is an<br />
Ideal Tool for Applications where Electric <strong>Circuitry</strong>, Field Simulation<br />
<strong>and</strong> Paracitics are Involved<br />
• Each Tool (Simplorer / Maxwell / Q3D) can be Used as a St<strong>and</strong>-<br />
alone Design Tool to Optimize Components (Signal Generator /<br />
RDC Algorithm / <strong>Resolver</strong> / Cable) in the <strong>System</strong><br />
• This <strong>System</strong>atic Approach Ensures Engineers from both Sides <strong>of</strong><br />
