You have AC servos (well one at least) > > > On Wed, Oct 29, 2014 at 12:59 PM, andy pugh <bodge...@gmail.com> wrote: > >> On 29 October 2014 16:47, Pete Matos <petefro...@gmail.com> wrote: >>> Mine came with DC >>> brushless servos and resolvers >> >> >> My next lathe conversion is very likely to be using brushless DC >> servos and resolvers. >> I like resolvers.
