4 Batteries
The controller is designed for operation with 24 V lead acid batteries. The batteries
may be wet or gel electrolyte types. Contact PGDT if you need advice on battery
selection.
5 Motors
The controller is designed to be connected to permanent magnet DC motor, fitted
with a suitable gearbox and solenoid brake.
In order to optimize the performance of the scooter, the controller must be matched
to the motor terminal impedance. The data sheet may define a motor compensation
value (normally 70% of the total motor, cable and connector resistance).
Failure to match the controller with the motors may result in poor control characteristics,
in particular speed stability on gradients may be affected, see Programming and
Diagnostic Technical Manual.
If you have any doubts about the suitability of a particular motor type or you need
advice on measuring motor impedance, contact PGDT.
These recommendations are derived from well proven field experience of various
international scooter manufacturers. Nevertheless, it is advised that manufacturers
confirm them by carrying out suitable tests. Keep wire lengths as short as possible.
If required up to 10.0mm2 wire gauge may be utilized with the High Current connecter
kits. However it is advised that manufacturers carry out suitable tests. Keep wire lengths
as short as possible.
Battery , motor and on-board charger (if fitted) wires should
use Tri-rated PVC equipment wire rated at 105°C.
