I would much more dub them Phases. Phase 1 would be from Turboranger to Timeranger. Phase 2 Gaoranger to Gokaiger. Phase 3 Go-Busters to Ryusoulger.
Phase 1 is the beginning, they started trying things they have not done during the 70s and most of the 80s dabbling with newer concepts such as narrative style in Jetman, motifs such as dinosaurs, ninjas, electronics, rescue, and time, etc. new team dynamics such as a team of high schoolers, fantasy teams, and siblings, and also established the tsuika senshi and bangai senshi.
Phase 2 is where technology evolved production-wise such as the use of HD and more CGI. They also tried out more new motifs such as police, magicians, treasure hunters, samurais, angels, and pirates. And heavy use of auxiliary combinations were made as well starting with Gaoranger, as well as big cluttered combinations such as Engine-Oh G12.
Phase 3 is where more new attempts were made such as more new ranger colors and sometimes bigger rosters, even more new motifs such as spec-ops/spys, trains, constellations, cops vs robbers, knights. Other new attempts I can think of are more non-human rangers such As Beet J Stag or some of the Kyuranger members, Lupin X and the show he appeared in Lupinranger VS Patranger.
I probably have missed a few details here and there but right off the top of my head this is why I would divide them into phases.
