Hi,
I am wanting to drive a DC motor as a generator to charge a battery for some data logging equipment.
The system will be 12 Vdc. I intend to generate with the motor at higher than 12 Vdc and feed this directly to the battery. This may mean a 15 V motor or I may run a 12 V motor at higher than rated speed.
I will put a diode in series with the generator and battery so that I do not try to motor the generator. The data logging equipment is all rated between 10 - 24 Vdc so I do not intend to regulate the load side of the battery.
Apart from the load capacity and battery size considerations is there anything I should consider with respect to using a DC motor for this application. ie., what sort of load does the battery represent to the generator, do I need to somehow current limit the generator?
Any help is appreciated.
