Best most efficient motor type to be used as a DC generator



I'm trying to design a system that requires a very light weight very efficient generator to be used from converting rotational motion into DC voltage(for say charging batteries) As far as I know BLDC's are the most efficient and light weight to convert the other way around electrical power to rotational energy


What would be the best motor type to be used in this app in term of weight and conversion power?(AC, BLDC, brushed DC?)


Thanks for helping.

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
