I have a text talking about the advantages of circular saw blades versus band saw blades in cutting aluminium castings.

The writer wrote, when talking about circular saw blades
"E’ mia prassi realizzare un unità di taglio con il motore rinviato, il quale permette di mantenere compatto il mandrino e riuscire a fare tagli anche di pezzi ingombranti"

I am not sure what he means. For the moment I am using "geared motor" I see that the word does indeed exist but I cannot find it in any dictionary.
