Traction Motor Type DR50/01AZ is a series wound, four pole, forced ventilated DC motor with high power to weight ratio, developed for use on broad gauge Diesel Electric Locomotives.

• Low unsprung mass enabling high locomotive speeds.

• Nose suspension with axle roller bearing drive.

• Arch bound commutator, dynamically seasoned, with L-shaped teflon ring protection.

• Heat sealed Kapton covered armature conductors.

• TIG welded armature.

• Polyimide film (Kapton), and PTFE tape based insulation for armature and field coils.

• Main field and compole coils bonded with poles for improved heat dissipation.

• VPI of armature and field coils in solventless polyesterimide resin (Class 200) to obtain void free insulation.

• Terminal box on motor facilitating connections with external circuitry.

• Reaction type brush holders for better stability and improved commutation.

• Fluonlex cables for brush gear cross connections and brush gear to field connections.

• Additional support for gearcase mounting.
