ELECTRIC MOTOR
The PowerDrive Plus vehicle uses a 48 volt shunt wound motor rather than the series wound motor that is
standard in other vehicles. A shunt wound motor is able to vary the amount of current passing through its
field coils while, at the same time, maintaining a constant current flow through its armature. This provides not
only more efficient use of battery energy, but also superior hill climbing ability. See Section 24 in this Man-
ual (Figure 24-8, Page 24-7).
MOTOR BRAKING
When the vehicle is in motor braking mode, the electric motor acts as a generator and produces an electrical
current that is sent either to the batteries (Regenerative Braking) or to the energy displacement module
(Dynamic Braking). While the motor is generating current, additional drag is created within the motor. This
drag is used to slow the vehicle as described in General Information about PowerDrive Plus vehicles, on
pages 21-1 through 21-5.
