Common commutator contact ring
Hi Anoop,
Yes there are issues with that design and I cannot say if it provides advantages over a symmetrical motor setup but as an asymmetrical motor one issue that I know UFOPolitics has mentioned is that the common connection means that each coil is always 'half way on' or charged.
One advantage to these asymmetrical motors we are working on building is the rapid change in resistance as it disconnects from the brushes and in this setup each coil gets the opportunity to free-wheel or idle (rotate without being energized by you're source). When there is a common connection the idle time interaction gets sent into every pole of your rotor at all 360 degrees of your armatures rotation each and every time a coil discharges (disconnects from your source).
A simple analogy is like a gasoline engine, each cylinder is isolated and has separated intake and exhaust, so that each cylinder gets it's own shot of fuel, and when that cylinder has used up the fuel it is allowed to discharge through a dedicated exhaust port to make room for fresh fuel as well as removing any remaining parasitic pressure which would take away from the machines capabilities. With asymmetric electrodynamic machines when you have a common ground you are introducing restrictions to the intake/outtake because each cylinder/coil is now dealing with the fuel and exhaust of every cylinder/coil no matter where the coil is at in its individual cycle.
