Key Feature 3 – Improving Electric Machine Efficiency
Calculation in Ansys Maxwell & Ansys Motor-CAD
Enhanced Space Vector Pulse Width Modulation
(SVPWM) Excitation Workflow in Maxwell
• Delivers consistent, fully periodic SVPWM behavior with on-the-fly
voltage generation
• New signal preview tools allow users to inspect carrier, comparison
& output waveforms before simulation
• Reference voltage is now defined as phase voltage, ensuring
correct & consistent behavior for both Y & Delta windings
Benefit:
Improved SVPWM excitation ensures expected drive
excitation, increasing value in loss & efficiency calculations.
Unified Performance Map Workflow for E-Machines
• Induction machine support now available, incl. automated
Maxwell-Motor-CAD integration
• New Look-Up-Tables (magnetizing/leakage inductance, rotor
resistance, iron loss) streamline accurate model building
Benefit:
Automatic steady-state detection & improved data-transfer
via new Python commands significantly reduce analysis time across all
machine types.
