 note = {Nowa-days，with tremendous increase in the use of automation has come an urgent demand for a servomotors. At the author's laboratory, two-phase servomotor was devised from common type squirrel-cage split-phase motor by replacing the laminated core cage rotor with a soft iron solid core, without secondary windings but short rings， and rewinding the stator coils. In this article the author first gives the preliminary descriptions about the various characteristics and constructions of servomotor which must be taken into account for design purpos，and then he explains designing data for windings and rotor constructions. Testing methods and 
operating characteristics are also shown with graphs，at last.},
