If your gearbox is 16:1 and the output shaft is spinning at 3408 rpm, that means your motor is spinning at 54,528 rpm.

An RS775-12 free speed is 7300 rpm, and an RS775-18 free speed is 13,000 rpm.

You numbers don't add up1.


1assuming the pronoun "it" in your post refers to the immediately preceding proper noun, i.e. the gearbox output shaft
