Hello, I am trying to design a regenerative/power system for a go cart. I know I can use a generator as a motor and vise verse, but I don't know exactly what parts to look for that will produce the best results. I would like to use this Motor/Generator as a regenerative braking system to apply a force to slow down the cart and charge the batteries, then use the same power to start it up again to assist the motor, minus losses. I need about 1-3 kW's. What kind of device would be best for this application, a basic electric motor? dedicated generator like those designed for small scale wind energy? Or a specific one that is designed for both capabilities? Any help would be appreciated. Thanks!
