traction motor drive system and method for selectively isolating fault conditions in a traction motor drive system

摘要

Summary "Traction Motor Drive System and Method for Controlling an Armature Pulser" This disclosure is directed to a traction motor drive system (200). the traction motor drive system (200) may include a field winding subsystem (202) comprising a field winding (105) associated with a traction motor (103). the traction motor drive system (200) may also include an armature subsystem (201) arranged in parallel with the field winding subsystem (202). armature subsystem (201) may include an armature (104) having first and second armature terminals and a grid resistor (211) selectively electrically coupled in series with armature (104). The armature subsystem 201 may also include an armature pulsator 212 arranged in parallel with the grid resistor 211 and electrically coupled in series with the armature 104. armature pulsator (212) may be configured when grid resistor (211) is electrically coupled to armature (104) to conditionally conduct current to armature (104). 1/1
