Thanks for your informative answer, I appreciate it. I think the core of your answer boils down mainly to the above text I left quoted from your letter.
I have pondered on what the best shapes and the number of segments for the rotor and stator of your rotary attraction motor setup could be chosen? i.e. apart from the minimum air gap attainable with precision, you indicated initially a cross shape (four bars) for the rotor.
I wonder if the number of the bars on the rotor is increased, do we get more torque? Naturally the on time in this case should be chosen accordingly (it reduces) and also the mechanical size (the 30 degree arc) of the bar also should be modified accordingly.
So what do suggest as an optimum solution for a given output torque?
My question is slightly related with that of Steven I have just seen his excellent animation/pictures but somehow I feel that the 5 - 5 segments on his stator should be supplied with 5 individual coil pairs (and not with 2 coils for the 5 - 5 segments) and switch on only one opposing coil pair at a time with the control logic means because this way the flux I create from the input can be focused to the rotor area just approaching for attraction.
What do you think?
