I have created a model of a transformer comprising a figure 8 core with face 1 of the primary and face 1 of the secondary coils in the first 'hole' of the figure 8 and face 2 of the primary and face 2 of the secondary in the second 'hole' with an air gap between the coils and the upper face of the core. I have flux deflection and don't understand why.
ok, here goes! If you can imagine a rectangular 'figure 8' core and inside the two holes i have placed a primary and secondary coil. The first face of the primary coil is on the left hand side of the left 'hole' and the first face of the secondary coil is on the right hand side of the left 'hole' and the second face of the secondary coil is on the left side of the right hand 'hole' and the second face of the primary is on the right side of the right hand 'hole'. I have an air gap between the upper of the coils and the lower of the core face of 5mm. I have measured in this gap in both 'holes' and in the left hand hole air gap the flux is barely negative and in the right hand hole the flux is barely positive, can anyone tell me why?
