On the Polypbase Series Commutator Motor

Abstract

The paper gives the results of a comprehensive study of the effect of bush angle and combined turn-ratio on the general characteristics in case of three phase series commutator motor, and further a new predetermination of the characteristics derived from a comparatively simple analisation of vector-diagram and saturation curve. Finally the performance characteristics calculated by means of this method are fully compared with actual test results obtained on a motor designed by the anther.
