The yoke of the rotor and a simulation with FEMM

Here's an other model of the Quadrupole motor.

In this picture, I have design the yoke to attach to the rotor assembly. Just need to add the coils and hardware to finish the job.

Below, here is movie of the FEMM simulation that was perform last October.

The simulation shows the flux orientation of the segmented rotor going in and outward to the stators.
