Traction Alternator ( DR101/03AZ replaceable with GTA17PB1 )

Traction Alternator DR101/03AZ meets the requirements of high horse power Diesel-Electric Locomotives of up to 3300 HP capacity, such as those of Indian Railways. This Alternator is suitable for rotational speeds up to 1100 RPM. This Traction Alternator is a salient pole, 3-phase star connected, separately excited, single bearing machine, directly coupled to Diesel Engine. Auxiliary Generator and Exciter mounted on the gearbox of the Alternator are gear driven, besides catering for Loco control system power and Alternator field excitation requirements respectively, act in tandem to crank Diesel Engine. Power Take Off Unit, also mounted on the Alternator gearbox, drives blower unit for providing cooling air to the traction motors. Some of the special features of the Alternator are:

 

  • VPI of stator winding and rotor field coils in solvent less resin of Class 200, to ensure void free insulation.

 

  • Brazed connections of joints of the stator winding.

 

  • Self ventilation with its own fan, thereby no need of external source of cooling air.

  • Alternator R, Y, B leads terminating in a terminal box, to facilitate connections with the rectifier.
