Laminated frameless stator construction with no separate housing.

Use of Zirconium copper (CDA Alloy No. C15000) a material with high tensile strength at elevated temperature, for rotor bars conforming to ASTMB747-07.

Heat sealed void-free polymide (KAPTON-CR of M/s Du Pont, USA) covered copper conductors for stator winding.

Roll baking of stator and rotor after VPI.

Glass backed mica paper (silicone bonded) tape for ground insulation with KAPTON film slot liners.

SG Iron cast end brackets for better mechanical strength.

VPI in SILRES H62 Silicone Varnish (Class 231) of M/s Wacker Silicones, Germany for better consolidation.

Application of anti-tracking silicone varnish on wound stator for adequate environmental protection.

E-beam irradiated halogen-free silicone rubber cables for supply connections.

Plug in pinion at drive end with oil lubrication for smooth transmission of torque on wheels for higher tractive effort.
