• Eccentricity script using “ACT” Ansys customization toolkit
• Automatically modifies existing Maxwell model for rotating part eccentricity, rotating axis eccentricity or both
• Simply specify the offset in same units as in model
• Variables are created which can be changed for parametric simulation
• Leaf model will use rotating part eccentricity dx,dy = 0, 0.2 mm (shaft is off-center vertically upwards)
