ELECTRIC LOCOMOTIVEAC TRACTION MOTOR
DR48/06AZ Replaceable with ABB*** Part No. 6FRA6068
Traction motor type DR48/06AZ is a six pole forced ventilated, 3-phase squirrel-cage induction motor is capable to deliver adequate starting torque at a low starting current for hauling a 6000 HP AC freight Locomotive.
Some of the special features of the motor are: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 and short circuit ring, brazed together.
Stator coils with heat sealed, void-free polyimide (KAPTON-CR) covered copper conductors.
Silicone bonded glass backed mica paper for ground insulation with KAPTON film slot liners, on stator winding.
SG Iron cast end brackets for better mechanical strength.
VPI in H62 silicone varnish (Class 220) of M/s Wacker Silicones, for void free insulation, with anti-tracking silicone varnish coating on wound stator for environmental protection.
Halogen-free silicone rubber cables for supply connections.
Plug in pinion at drive end with oil lubrication for smooth transmission of torque to the Loco wheels for higher tractive effort.
