Cat AC Electric Drive in Retard During retarding the wheel motors become generators. Motor power is fed back through the DC link. The power is fed to the contactor and chopper circuits and then exhausted through the radial grid. An AC fan blows air across the grid to dissipate the power and control retarding speed. Generator/Alternator The chassis mounted 795F AC traction generator is a threephase, two bearing design. The excitation system is brushless which has longer maintenance intervals than brush type systems. Inverter The Inverter uses Mitsubishi Electric IGBT Phase Modules to control...

Building on the legacy of superior, long life structures. Box Section Design The 795F AC uses a box-section design, incorporating forgings and castings in high stress areas with deep penetration, continuous wrap-around welds to resist fatigue from racking loads. Steel Structures – Mild steel used throughout the frame provides flexibility, durability and resistance to impact and allows for field repairs with common weld practices. Castings – Large radii castings dissipate stress in areas of high stress concentration. Castings allow welds to be placed in lower stress areas for longer frame...
