Advice: Position the biker in a recumbent position. Aim for 80...90 RPM for the *biker*. Aim between 100...200W for the biker depending on his condition. 90RPM @ 100W is something anyone can do for a few hours. That's why you need the recumbent position: to make it comfortable. If you want to do peak powers for a recumbent postion, you will have to be able to sink more than 1kW of power. And you will probably need to feed that back immediately to fans for cooling and fresh oxygenated air. I would opt for 100..200W for 4...10 hours a day... This is the first build I've seen that has a fly wheel, which is absolutely necessary for comfortable biking.
Impressive result. Mine was able to give over 100 Watts here you have over 200 but construction is much more simplified without unneessery power loss elements . Good joob
Oooh, this isn't any old motor, it's an orbital flux. Anyone looking to make this, you're going to need a newer dryer to take apart. Well done! I've been waiting for someone to do this! I want to try an axial flux layout. I believe it's more efficient, more compact.
Most of these washers fail because the spider holding the tub dissolves. You can pick them up in most tips. Just need to make sure the bearings aren’t shot as well.
Totally brilliant idea, sitting on a turbo trainer just producing heat from friction is such a waste. Can't wait for my LG direst drive washing machine to give up the ghost! haha.
8:55 as discussed below, measurements made when there is a resistive dummy load in the output circuit are not accurate and the amount of input force required is less-than normal.
Awesome Video !!! Thank you for making this... The wind does not always blow, and the sun does not always shine ... now gravity - gravity is always present... What would be your thoughts on setting up a series of cascading weights that drop from a height of 10-15 feet towards charging a 12V 100Ah battery? Would something like that work? How long would a single weight drive the generator... a series of 5 weights? I have this idea that a series of weights dropping from a reasonable height, through the right gearing, could drive a flywheel / generator (low RPM) to charge up one or more batteries. Repeated raising and dropping of the weights is an easily resettable system. I've been asked how the weights would be reset ... I think simply by pulling on a rope connected to the weights back up to a height using our own body weight. Grab high up on the rope and lift your feet off the ground. A typical male adult should be able to raise up a 100 pound weight using this method fairly easily. A weight dropping generator could be in every home across the globe ... no reliance on wind or solar .... just dropping a weight.
I wish you hadn’t zoomed in the multimeter and cropped out the battery charging measurement, that’s where the rubber meets the road. what was the peak amps going in the charger?
Please share some data about this generator,,? If this generator is made single phase,, then how much turn in each slot,? How much Ohm is the total resistance of the coil,,? What is the SWG of coil wire,? How much pole of permanent magnet is used,,?? What is and how much webber is the useful flux of each magnet pole,,??
the usual multitude of mistakes are here beginning with, Not really knowing what a Nominal output value is. in order to accurately measure/estimate output volts and amps, the rpms Must be reduced; as though the system were in operation. the easiest way to do this is to Short the rectifier output. (as far as i know, for brief periods this does not damage a rectifier.) volts can be accurately measured or estimated based on the reduced rpms. amps can accurately measured (at the reduced rpms) via the use of a clamp DCammeter, on the shorted power-out circuit. this is a radial flux bldc motor. the stock configuration of the rotor is very much less-than ideal for use in an alternator. appropriate optimizing modifications to the rotor were not done. it is not clear whether the rewiring of the stator was wonky and/or inefficient. 6:55 this is a wonky, high-loss drive mechanism. googletranslate
Well, depending on your energy needs. An average household in Europeconsumes about 420kWh per month, meaning that you have to generate 14kWh per day. Given that the generator shown in this video can generate about 300Wh per hour, you’d have to spin two of these for 23-24 hours without stopping. However, in my case, I consume only 80-100kWh per month living in an Eastern European one-bedroom apartment. So if we take an average 90kWh / 30 days = 3kWh per day, I would need to be pedalling for only 10 hours daily. That’s still quite a bit, but if you supplement it with some solar panels on you balcony, then it’s a pretty doable thing to power a house during sunny seasons
@@TheOnliner Since I get frequent outages in other parts of the Philippines (No panels too because unaffordable), someone is gonna do a more makeshift generator because water and electricity maintanance is poorER here.
No 17 amps at 13.8 volts is 234.6 watts you might charge a battery and run a couple led lights from an hour of hard pedaling maybe power a tv while peddling
