摘要
This invention pertains to a direct current, series excited traction motor, the armature coil of which is connected in series with the field coil and a smoothing coil, and the power supply of which is adjusted by a current chopper. The inductor includes, in addition, a shunting device for reduction of excitation, and a free wheeling diode is in parallel with the motor and the smoothing coil. This device is unique in that the field coil is divided into at least two series connected partial coils to generate additive flux, one of them only being provided with the shunting device. The chopper is advantageously of a type which may operate in a continuous conduction mode.
