problems with the Model ECE and ECER

      Hi there,

      I tried to use ERE3 and ECER Model to make a current and angle sweep analysis for my 3-Phase,12Poles PMSM Motor.

      I want to have a current sweep between 0A and 400A, an angle sweep between 0deg and 10deg.

      And the results came out strange.

      -for current: I thought I would get a current Interval [-400A,400A], with 100A as a step. 

      -for Angel: I thought I would get an angle Interval [0deg,10deg] with 5 steps.

      As you can see, the results are not what I have set. 

      What I try to do is the same in this link:https://www.mathworks.com/content/dam/mathworks/mathworks-dot-com/solutions/automotive/files/mac2017/deriving-fast-accurate-pmsm-motor-model-from-finite-element-analysis.pdf 

      There are some examples of settings on page 26 so I did the same. But the results came differently.

      Hello Zhengting,

           For the circuit, please deactivate coils and delete current sources, so we need 3 deactivated coils for 3 phase winding, ECE3, ECER and ground. 

            Please reviewe the tutorial in ALH if possible, https://jam8.sapjam.com/groups/NA4AXmq6h4aU43Ap36G0uU/documents/slMdBzf6vnLU0adOCR02h2/slide_viewer

           Similar circuit in,  ECE for SR motor

           Thanks.
