INTRODUCTION OF THE SELF-DRIVEN SYNCHRONOUS MOTOR. GENERAL, OPERATING PRINCIPLES, DIFFERENT LAYOUTS

In the first article the author begins by explaining the advantages of a traction system comprising a self-driven synchronous motor fed from a current inverter. He continues with a simplified description of the operation of this equipment and the methods that can be used to ensure smooth starting. Various layouts are proposed for tractive units working on a single-phase current, direct current or dual current in the different variants: "double star" or "single star" synchronous motors. The operation of the electric braking system is described. A special safety feature is incorporated: the rheostatic braking works without any difficulty, even when the traction current is cut off. In conclusion, the author summarises the strong points of this system which is remarkably well adapted for the construction of tractive units of all types: locomotives, high-speed or suburban trainsets.
