Three-Phase Voltage Imbalances in dual stator electric generator

  I am experiencing an imbalance in the three-phase voltage output of my generator model in ANSYS Maxwell 3D. Despite multiple attempts to resolve the issue, the imbalance persists. I would appreciate guidance on how to address and eliminate this voltage imbalance in the model.

  Hi,
  In general, if you are running a transient calculation, please ensure that the time step is appropriately related to the speed and the airgap segmentation angle. Keep in mind that this solver does not include adaptive meshing, so it is important to use mesh operations to properly mesh the geometry.
  If you are using an external circuit, please include a small resistor for each winding to help stabilize any imbalance in the external circuit.
  Also, make sure that the winding and boundary conditions (if used) are correctly defined.
  I hope this helps you
