Hi Sykavy,
Well I don't really know if the solenoid piston design has significant advantages over the 'normal' switched reluctance motor design. On the one hand one might think there is better flux interactions since the coil encapsulates the piston core. But on the other hand you must have some support system to guide the piston, which results in noise, losses and wear.

There are so many different types of Reluctance motor design out there you wont' believe. Here for example is an interesting addition:

Also another method for reducing the air gap size is having 'slots' in the stator and rotor core elements, so that the rotating parts kind of interlock or 'mix' with each other.
