Brushless Hub motor as 3 phase generator

Example of using a Golden Motors 48v 500w brushless hub motor as a generator. Hub motors make excellent generators as they produce useable voltages at very low RPM. Just turning the pedals with one hand (~110 rpm at motor) it can produce 15v @ 3 amps (45 watts). Brushless motors are 3 phase and require rectification with 6 diodes or (1 1/2) bridge rectifiers. Pick one that is designed more for torque then speed, 8-9 rpm/volt works best.

DIY Pelton Hydro Power with a 500W EBike Hub motor
Used a 500W hub motor and some spoons to make a pelton turbine hydro generator. This is the working generator running off of a garden hose. The plan is to take it up to the gold claim and use it to power the cabin and charge the batteries that I use in my wash plant.

The inside of an e-bike hub motor, with planetary gears.
Showing the inside of an e-bike hub motor, with planetary gears. This motor can also be used as electric generator, for alternative energy projects, because it has magnets inside. Its a 3 phase brushless motor. To get DC out of it, you'll need a 3 phase full wave bridge rectifier circuit.
