Salient Features of Traction Motors
  • Designs equipped with brush-rocker assembly, terminal box and axle roller suspension bearings.

  • Polyimide film covered conductors for armature coils.

  • Armatures built with high permeability electrical sheet steel.

  • Potted field coils for better heat dissipation.

  • Use of curved field coils on traction motors with round magnet frame for improved heat dissipation and space factor.

  • Higher temperature class, moisture resistant glass banding of armature.

  • TIG welded armature coil to commutator riser connection joints.

  • Arch-bound commutator construction.

  • PTFE ring protection on commutator front V-ring for effective Creepage

  • Robust brush-holders with Micalex insulated pins.

  • Arcing horns or rings for protection against flashovers.

    • Sealed armature bearings necessitating re-greasing only during overhauls.

    • Protection against over-filling of gear case.

    • Felt-wick lubricator for lubrication of axle sleeve bearings.

    • Gear wheels & pinions of case-carburised or induction hardened or through hardened type.
