The Finnish company "Visedo" has developed a prototype SR motor that they claim has minor improvements over previous designs (a hybrid SR plus permanent magnet configuration, "SRPM"). They are developing large motors for city buses, boat-ferry's, etc. Based on the performance of the prototypes, they have raised a lot of money for expansion...

In the pic above, I am very impressed by how large the hairpin copper-bar coils are, fairly easy to replicate in a garage, using laser-cut steel to assemble a stator. (it sounds like the poles in an SR motor don't change magnetic orientation, so laminations are not a requirement, I just meant that the stator is so thick, it would be easier to order sections that we rivet together)
