Abstract SELF-EXCITATION TRACTION ALTERNATOR FOR LOCOMOTIVE A self-excitation system (106) for a locomotive (102) having at least a primary mover (104) is provided. The self-excitation system (106) may include a traction alternator (110), a permanent magnet machine (108), and a chopper circuit (112). The traction alternator (110) may include an alternator stator (136) and an alternator rotor (138) mechanically coupled to a drive shaft (140) of the primary mover (104). The permanent magnet machine (108) may include a machine stator (142) and a machine rotor (144) mechanically coupled to the drive shaft (140). The chopper circuit (112) may be configured to receive electrical signals from the machine stator (142) and control a field excitation of the traction alternator (110).
