Motor application to machine

The subject of motor application to machine tools is rather a difficult one to treat satisfactorily in an abstract way. However, in this paper I shall try to point out the fundamental principles underlying motor applications to machine tools and trust these these will aid, not only in the election of the proper motor; and control, but in their application to machine tools as well. Observing these principles will have a marked effect upon production and will reduce maintenance to a minimum.
