 note = {This paper proposes improved secondary excited speed control systems of wound rotor type induction motors. These new systems consist of the following three parts: (1) Scherbius system using differential gear. (2) Scherbius system using secondary excited induction generator. (3) Kramer system using differential gear. A distinct feature of these new systems over ordinary systems is that the secondary electric power of induction motor is separated into two parts and transmitted to the electric power source or to the shaft of the induction motor. These new systems have a merit that capacities of part of auxiliary apparatus are decreased greatly., Article, 信州大学工学部紀要 10: 146-154 (1960)},
