Power Train – Cat AC Electric Drive
Delivers you more power to the ground for greater productivity.

100% Caterpillar
Designed and manufactured by Caterpillar, the 794 AC is a
291 tonnes (320 tons) AC electric drive truck that is single sourced
from one manufacturer and supported with the best dealer
network in the industry. The 794 AC drive system works seamlessly
with
the C175-16 engine and offers exceptional safety, serviceability
and performance.

Modular Design for Excellent Serviceability


The modular design allows for easy removal and installation of
components. The engine, traction alternator, motors, inverter, grid,
and final drives can be removed independently. The close coupled,
dual bearing traction alternator allows for easy mounting to the
C175-16 engine.

Superior Control Inspires Operator Confidence


The Cat AC drive system gives you the best retarding, braking,
and control in the industry. Class leading dynamic retarding
coupled with blended service braking of the four corner wet disc
brakes, provide the operator with exceptional control and
confidence.

High Voltage – Lower Heat


The Cat AC drive is a high voltage system (2,600 volts) that operates
at lower current than the competition. The result is lower heat
generation, smaller/lighter components, and longer component life.

The Cat AC Electric Drive in Propel


The C175-16 diesel engine drives the close connected Traction
Alternator/Generator through an isolation coupler. The AC power
is rectified to a nominal 2,600 volts to form the DC link. The DC link
supplies power to the Inverter where IGBT’s convert the DC signal
to 3-phase AC to drive the traction motors. Traction motor output
drives the wheels through a double reduction ring gear output
final drive.

Cat AC Electric Drive in Retard
3
During retarding the traction/wheel motors act as generators
and power is fed back through the DC link. The power is fed to 2
the contactor and chopper circuits and then exhausted through
the radial grid. An AC fan blows air across the grid to dissipate the
1
power and control retarding speed.

Traction Alternator 4
No shimming or radial alignment required with the close coupled,
dual bearing alternator, resulting in decreased install time.
The excitation system is brushless which has longer maintenance
intervals than brush type systems.

Inverter

Cat ECMs and software work with the Mitsubishi Electric IGBT
Phase Modules to control the rimpull, direction and speed of the

truck. Mitsubishi Electric IGBT technology is the proven leader
for AC drive systems.

significantly quieter than box grids. The AC electric motor does not
require any maintenance, which is a savings to the customer over
DC motor systems.

Power Train – Engine
Delivers power, reliability, and efficiency
for your most demanding mining applications.
Engine Block
The C175-16 engine block is comprised of
a high tensile strength ferrite ductile cast
iron alloy. This design offers increased
resistance to stress cracking and offers
support to the cylinder liners, allowing for
increased head gasket sealing capability.

Serviceability
The design of the C175-16 enhances
serviceability. The inlet manifolds and
turbochargers are located outside of the
engine’s V, giving the service
technicians more space to work on top
of the engine and within the engine bay.

Electronic Control Module (ECM)


The ECM utilizes advanced engine
management software to monitor,
control and protect the engine utilizing
self-diagnosing electronic sensors.

Engine/Power Train Integration
Delivers low operating costs through
electronically combined power train components.

Control Software and Integration


The Cat engine, AC drive system, hydraulics and controls have been integrated to make the truck easy to operate and provides:
• Excellent slow speed control for safety within the service areas.
• Superior throttle response on acceleration to move out of the loading or dump areas.
• Dynamic retarding with blended four corner wet disc service brakes, at low speed.

Cat Data Link


Cat Data Link provides one location to access all machine information from all machine sub systems. Unique tools are not
required to access the drive system, engine and machine information. All systems on the 794 AC are in constant communication
with each other to:
• Optimize power train performance.
• Increase reliability and component life.
• Reduce operating costs.

convenient access to tank levels, filters, drains and S·O·SSM
oil sampling ports.

Servicing Ease
• Open engine access with service platforms makes
maintenance easy. Traction alternator and optional
inverter platforms allow for easier inspections,
troubleshooting,
and component change outs.
• Hydraulic cabinet shows critical pressures for all
key systems in one centralized location.
