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.
First Power Up - 10kW Brushless DC Hub Motor
Re-uploaded because the original file was corrupt. Everyone is excited about Graham's new Hub Motor that just arrived. So we powered it up from a random controller that was lying round. See comments for more info. Aslo: http://www.enertrac.net/product.php#a
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.
Electric Motor to Motor, can they self run?
There is a idea floating around the internet about self running two motors that are connected together. This is just a Demo of two 12v Dc PM electric motors connected together with a small flywheel between them, the idea on the net is one motor acts as a drive motor and the other as a generator when spun up the claims are the two motors can run each other like a closed loop can this work? This video is just a basic experiment and explanation, I don't go into detail and there are many factors involved. I have a small flywheel in the middle of the two motors to address kinetic energy, I know it's not balanced very well and it's crudely built. This is just a simple experiment good for a kids science fair project can show motor to generator AC to DC current, etc. This is only low voltage. Don't forget about the laws of Physics, conservation of energy -Energy can be neither created nor destroyed but can only change form.
