B.A.E.™ Hybrid Propulsion System

Alternating Current
Traction Motor (ACTM)
The ACTM converts the electrical
energy from the Alternating Current
Traction Generator (ACTG) and the
Energy Storage System (ESS) into
mechanical energy to drive the
vehicle wheels.
The motor drives the differential,
which in turn drives the wheels and
propels the vehicle for acceleration.
During deceleration, the reverse
torque from the wheels is directed
back through the motor. This allows
the Traction Motor to act as a
generator and return energy that is
normally dissipated as heat in the
braking system into the battery
system for use. This condition is
known as REGENERATIVE
BRAKING and is similar to the
transmission retarder feature of a
conventional vehicle.
Motor Speed Warning
Indicator
This red audible indicator warning
light illuminates if the vehicle’s
speed exceeds 103% of the rated
speed.
When this condition occurs, the
operator should apply the brakes in
order to reduce vehicle speed
(ACTM rotor speed).
If the vehicle speed continues to
increase, the PCS will automatically
reduce the torque applied to the rear
wheels to zero in order to slow down
the vehicle.
The indicator light will remain
illuminated and an audible alarm will
continue to sound until the ACTM
rotor speed drops below 100% rated
speed.
If the ACTM rotor speed (vehicle
speed) continues to increase to
110% rated speed, the PCS will
shutdown the Traction Motor.
Electric Alternator
System (EAS)
New with the EPA10 vehicle, the
EAS is located inside the rear upper
compartment door to the right of the
PCS. The EAS was introduced to
replace the functions of the
standard engine alternator. For
additional information on the EAS,
consult your Orion Service manual.
WARNING
If the speed is not reduced by
using the vehicle brakes when
the Motor Speed indicator comes
on, damage to the hybrid
propulsion system may result.
