AC-77

11,000Nm AC replacement for D77 DC traction motors

Highlights

  • Mechanically compatible with D77 motors
  • Uses existing bull and pinion gearing
  • Continuous and peak tractive effort improvement over D77 equipped locomotives
  • Typical DC motor drawbacks such as armature commutator damage, “carbon tracking”, frequent brush replacement and commutator repair, are nonexistent with the AC induction motor
