In this video we are going to built a small electric generator using a gasoline engine.
This generator is powered by a 36cc Four Stroke Engine. For the generator we are going to extract the permanent magnet brushless hub motor from an old hoverboard.
The motor is altered to work as a generator for which we are going to attach a 55 teeth spocket to the hub motor. Next we have removed the hall sensors which are of no use in our case.
The engine is attached to the motor through a centrifugal clutch. This allows us to engage the engine to rotate the motor when we increase the speed of the engine.
The frame of the generator is made using 1 inch square metal tubing and 3mm thick metal sheet.
Since our hub motor produces a three phase alternating current so to make it more useful what we are going to do is to design and built a three phase rectifier circuit which allows us to convert three phase AC into DC output.
The schematic, gerber files and the list of components for the rectifier circuit is avlaible here:
