servo and gearhead mounting

[lgalla]

When looking at steppers they are NEMA23 34 etc.When looking for servos and gearheads there is many with 60 size frame 90etc.OK so I assume there is 2 different mount size flanges.NEMA and metric.Is there such a thing as an adapter plate?Some of the gearhead manufactures claim any servo can be mounted to their gearhead with their clamping hub.
The question would be,I have size 60 gearhead.can it be adapted to NEMA23?
Thanks

there are lots more than even those 2 standards. yep, nema and the metric is called IEC sizes. I have experience with thomson micron & stober gearheads: both will mount to ANY motor - within reason. there are limits to min and max shaft diam and then of course flange size must be adaptable. these and others like alpha typically just ask for the exact motor part no customer plans to use with a given bo and then provides that adapter plate for typically no additional cost. if one gets hold of a used box then of course they will have to pay for the adapter plate and coupling piece(s).

any distributor for your brand gearbox should be able to get you a part no and price for your exact motor if you ask them.

Thanks mike.
Us guys with little or no money should be careful when buying from E-Bay to get a match.I would hazard a guess an adapter would cost more than I paid for the units on E-Bay.I E-mailed Wittenstein to ask if my servo would mount to their Alpha series 60 and they did not seem to understand.I assume they are not interested in any help to the small guys.May have to re think and return to belt drive
