    Synchronization and synchronous devices
    Gregg, N. L.; Jarvis, J. S.; Naylor, H. E.; Watson, R. W. (Virginia Agricultural and Mechanical College and Polytechnic Institute, 1934)
    Object: To construct a synchroscope for use in the Electrical Engineering Laboratory. This synchroscope is to be small and a very compact unit, which will be portable and of such sturdy construction that it will not be damaged by the frequent handling of students. Method: After a thorough research of the existing types of instruments, a synchroscope of the Lincoln type was chosen as best suited for the given object. The construction of this type of synchroscope is essentially that of a wound rotor induction motor. This involves the construction of pole pieces, field coils, and a wound rotor. Conclusion: After the construction of our synchroscope was completed, we proceeded to test it out in the laboratory. We found it gave positive indications of synchronism in every case, and we were more than satisfied with the results obtained. Although our work was comparatively poor in relation to that done by men who have spent their entire life on such subjects, in consideration of the time and materials that we had to work with, we feel that we have accomplished our purpose and have derived a great deal of benefit from our year of work.
