Good Afternoon /Evening/Morning depending where you are.

I am trying to model a Tubular Flux Switching Machine in order to be able to achieve the best dimensions to buld the prototype.

The machine target of further development is the 10 pole-12 slot combination being the slot pitch T_S=10T_P/12. The electrical angle between the coils in adjacent stator slots, i.e. the phase shift between two adjacent phases has to take in account the existence of the phase introduced by the magnet between each other.

The winding configuration: coils from the same phase are set in a single slot and connected in series.

It's a three phase machine where each phase is in a diferent stator slot. The stator consits of a C-iron core (in a axialy simetry point of view) with the coil between the stator teeth, and a magnet sandwiched between each stator slot.

The translator is a iron piece with a "shaft" and teeth.

The model is analyzed in a two dimensions system (r,Z - Axial Symmetry (2D).) due to its uniformity around the axis (r=0). The analysis is done using the application Mode - ‘Quasi, Static Magnetics – Azimuthal Induction Currents , Magnetic Potential , within the AC/DC Model , also it is further added the Deformed Mesh in order to do a trasiente analisys.

When I set a predescribed movement for the translator , eventhough the movement occurs the magnetic fluxes don't change according to the movement of the translator , the flux lines stay static as in the first analisys.

I would like to know if any body as an ideia why this occurs.
And once the movement is set how to plot the flux linkage change and back-emf in the coils.
The machine as to work as a generator and as a motor. So with an input current and without current.

The very best regards!!!
