Hi, I am trying to incorporate actual rotor displacement (measured from the experiment under eccentricity fault, shown in the figure) to my Ansys Maxwell model under transient analysis. Could anyone provide me with some suggestions? Thanks.

Hello Abdur,

        Could you find free eccentricity tool in ACT of Ansys store? then you could use this tool to build Maxwell transient model with eccentricity (shaft displacement).

Hi HDLI, thanks for the suggestion. However, I was looking for a way to incorporate the experimentally measured shaft displacement (arising from unbalanced magnetic pull) into my maxwell transient model. For example, in ansys mechanical, one can define force at different time instant. Similarly, is there any way to define shaft position or displacement with respect to time in maxwell transient analysis?

Hello Abdur,

       What is your motor type? Is it PM motor?

Hi HDLI, yes it is a V type IPMSM motor, rated speed 1300 rpm, max speed 6000 rpm, rated power 1kW. 12 slot 10 pole FSCW IPMSM.

Hello Abdur,

        If it is the PM motor, you can use magnetostatic solver and parameter/torque, to do parameter analysis for rotor center position and current to match your experimentally measured shaft displacement.
