 note = {application/pdf, A static　Kramer　system　having　a constant　output　characteristic　has　the weak point that it can not change the supplementary machine to a static system. However, recently, this system has widely received practical application for minute speed control because it is composed of simple equipment, and it is able to be controlled stably and efficiently by adjusting the exciting current of the d-c motor. 　Already, we proposed the new circle diagram method of analyzing the characteristics of a static Kramer system by using a simple equivalent circuit considering the effect of d. c. voltage drop to be caused by the commutating period, forward voltage drop of the receifier, and brush voltage drop.　In a wound-type induction motor, a no-load current is generally 30 to 50 per cent rated current. Therefore, it is inaccurate to calculate the characteristics by using an L-type equivalent circuit. Then, we applied a T-type equivalent　circuit　to the static Kramer　system　and analyzed the characteristics by a T-type circle diagram method.　As a result of the analysis, we pointed out that this T-type circle diagram method can derive sufficiently precise results in the practical region of slip from no load to full load, by considering the effect of overlapping angle and using coefficients dｅpending on the commutating period.},
