Your video was NOT a fail. You learned things, and informed people. That is a PASS.

I made a simple generator out of this motor and a stationary bike. Friction connection to a flywheel of the bike with help od 3D printed bracket. 3 phases connected to a commercial rectifier like the one on the video. Then a boost converter (with potentiometer to set the resistance) and a 7S battery pack. It reaches over 200W but it requires a lot of force on the pedals. Better than wasting that energy to heat when exercising 😅

The standard for continuous human output has been 1/10 HP since the steam engine was invented. 1/10 HP is lifting 55 lbs 12 inches every second. A 40 hr work week would total 3 kW-hrs. 200W is 0.268 HP

Failure videos are sometimes the best to watch. And also - kudos for the time disclaimer for those who are after the information.

A friend & I built a wind turbine using a direct drive single hoverboard motor about 7 years ago. I overcame the startup torque problem by connecting an Easy VLC module. This can be programmed to switch the load on when a certain voltage is reached (in my case 14.8 for charging a 12V lead acid battery). It allowed the motor to spin up to charging speed without a load (around 200 rpm) before engaging the load. The second VLC on-board relay also switched on a dummy 3 ohm load when turbine speeds reached uncomfortable levels, to slow it down. I also added a brake by shorting the phase wires together using a push on/off switch activated by a solenoid via a remote control switched circuit. One hall effect sensor in the motor was used to read RPM via Arduino and radio frequency remote transmission.

I freaking love how you break things down! I just did it with my son’s broken hoverboard. The only thing, I’m waiting for you to redo this vid so I can connect it to my 3d printed wind/water turbine! Love the vids!🫡

I'm printing a lathe chuck. Going to attach it to one of hover board motors. I'm betting it make a great lathe.

I have tried to make a wind turbine out of the hoverboard motor. There is some issue with the magnetic resistance or something. Long story short, it wont spin at lower wind speeds and difficult to start spinning at higher wind speeds. When I compared the spinning resistance with a commercial wind turbine, it was day and night difference because wind turbines start spinning at very low wind speeds and when wind speed rises it is already spinning and wind turbine works at best efficiency. Hoverboard motor wont even start in most cases and when it does it is inefficient. I worked with commercial small (500-1000W) wind turbines and have noticed that those wind turbines have coils without any core, so maybe that is an issue with these motors when used as generators. Since then I abandoned my wind turbine project and the prototype is laying in the storage room.

I was looking at this hoverboard motor to use as a generator in which I intend to build a DIY battery for my solar energy storage and I was researching for the data that I need and you explained it correctly now I need the actual power ratings.

These motors are awesome i made 3 wheeler from these motors with 10" tire and 4x20ah agm batteries top speed is 37km/h and battery lasts around 35km on max power 👍👍 and weight is about 25kg and it can tow about 400kg

Great project. Success or failure, I learn a lot from your videos.

Using those motors for a wind turbine is certainly a very interesting idea. Good video! ☺

Clever project! I know when I go to the electronic recycling center its just an amazing amount of perfectly good parts that are being disposed of for whatever reason. Printers have some really fun bits. Also if you have an autowrecker nearby the sensors off the bumpers are very cheap and really fun. I'm thinking you have a robot ROS project in your future! You might consider a Savonius vertical windmill. You can 3D print the impellers and mount the motors in the vertical plane down at the base where you can also put the battery and BMS. Its omnidirectional and does not need to pivot so much less complicated mechanically. And because all the weight is in the base its somewhat portable.

Thanks!

Have seen some trials like this and as is (without any transmission in between), most fail due requiring high wind speeds to start spinning to a useful rpm. So consider adding one for your project also maybe, and to do something different, use a vertical axis wind turbine as they are simpler since they dont require to track the wind plus require less "volume per watt". Finally blade design is more forgiving and could be made from PVC to make the prototype faster.

Am from Jamaica, and I would like to learn more about how to make brushless drivers, I managed to make the half bridge, with neutrual point going to + voltage, but i want make a full wave, that's more powerful. Hoping you could taught me how

a cool project. i hope you dont give up!

I don't think this video is a failure. Maybe you didn't reach your original goal but I think it was still informative and I am looking for scrap hoverboards and escooters as we speak 😂

I built a turbine with one on the top and one on the bottom (phased 'em 6 phases) and used the bearings (top and bottom) and a homemade VAT in between. You can series or parrell connect the output as you please!

If you would like more info about how I did it I'm glad to share more.

I would connect the generator output to various values of power resistors, measure the voltage drop across those to calculate the current and also measure the total voltage, then graph out all those values to work out the maximum power point :D Also connect the sense wires to something to record the RPM

Great video, I was thinking of the ac ripple and thinking that you could absorbe the energy at low voltage stages and put them in series, dump them in battery then charge them back in parallel. This will put the generator in a low rpm high torque draw That way it will not waste time generating high voltage to fill battery.

hi there, big thanks for your content! i would like to ask if a bleeder would makes sence for safety and which bleeder would fit? Another question - what about changing the motor windings to /delta connection for having less torque? thanks and regards

I'm afraid that the start torque on these motors is so high that they wont spin i low wind conditions. Rewinding the connection to Delta from Star might help you get more power from the motors in decent wind conditions. These guys rewired would give way more than 200w, from my skateboard running 4 of these in Delta I peak each motors up to 700w.

You have right, be default, they will don't spin. To work properly in low wind you need rewinding them but not to delta but change the way the wire is joined in the coil. By default, they have 3-5 thin wires per coil connected together parallel, you need to change that to series connection (end of one wire connect to other end) - then in the same wind speed you will have more volts and less amps but it will spin. In full speed, it will reach more than 200V.

I really enjoy waching contents like this. I mean recycling sth and make things that either produce electricity or are handy. Please make these kinds of videos more❤

Very cool project. i hope that works fine

You can relatively easily replace 3 of the low side diodes with mosfets and a comparator/IC to reduce the voltage drop of the rectifier in almost half, that would be significant at low rotation speeds where the voltage generated is low.

I can't wait for that driver board analysis and repurposing video. Clamping that chassis with some wood clamps to the table could free you one hand:). I loved the vid anyway. Keep on the good work.

Outstanding look forward to you stacking.

You could try gearing and chain , to overcome torque needed to rotate hoverboard wheel. As a wind turbine .

Try to reduce the cogging of these motors by removing some metal from the stator laminations only 1mm, max 2mm, it depends on the coils, after decogging the motor shoud rotate more freely, then you can compare one "generator" decogged and one stand. Thanks

Hello there! I've a question. If you connect one of those motors to a controller, to generate movement you have to convert the DC to a Three phase AC right? So, if you use it as a generator, if you spin the motor, aren't you doing the opposite? Converting the three phase AC to DC? Thanks!

A cheap, long life weather resistant generator can be found on most cars. Self regulating too. The KV rating of the 3ph motors is crucial to select for generation. IE 770KV needs 770 rpm to achieve 1 volt. Also remember that 1hp equals about 750 watts (1.6hp = 1kw), so consider the torque input as well as rpms. Do the math then design. Good luck!

Disassemble the two halves of the hoverboard. Install motors. Place side by side. Remove Rubber tires. Connet the motors with a belt. Run one motor as a motor, and the other as a generator. Profit! )

Seperate all batteries and charge them individually , make sure to use a metal tin . And be observant as they charge... if you have them in metal tin ,least you can move them if they caught fire . But then you know for definetly which cells were dead .

Awesome project bro👍. I think you should collaborate with great Scott or electroboom.

you'll need big blades and a tall post to use one motor directly, gearing will be necessary. test it with a hand crank.

Stick to your channel 😅 still watching ❤👍

Just make a metal Y shaped prongs and attach it to the drill on one side and other two should hold the tire firmly so that you can make it rotate using drill.. it seems easier than alternating the alluminium casing

Hmm... If you making a generator with that, you need to rewire it in parallel so you get a lower voltage & secondly you can't depend on it full speed output unless you making a gear system for it.. Maybe if your target voltage was 12 volt, I might decide to make it double that amount. Since at lower speed may range that area of 12 volt or so. You can also use voltage regulator but the current most be rectified first.

I would connect those two motors in series then to dc to dc boost converter to get more than 100v and to mppt controller and after all check what real power it outputs 🤔

Do you think Axial Flux motors would work better?

use one motor to drive the other motor, sond the second motor you put 10x100w bulbs and a watt meter in parallel to the rectified output. then you can just drive the input motor ... , you have to meassure the temperature on both motors constantly , not to fry them.

You can use the motors to make a motorised sofa for example...

the higher the power you want to draw the harder it is to turn the motor , i dont think your going to have enough wind to power the huge motor your planning to make by combining the 2 motors , unless your going to make a 1 meter blade or something ridiculously big like that . me personally i would rather have a turbine that turns and generate a small amount of power from the smallest breeze ,then to have a turbine that doesnt turn at all most of the day also maybe use a gear box to have higher rpm ,also dont forget to have breaks on the turbine itself so you wont have a runaway turbine in bad weather your a smart boi !! you will figure it out

No es mejor poner cada motor en un molino separado?

Can you combine solar panels and wind turbines? Fins of wind turbine will be made of solar

this type of generator requires (Maximum Power Point Tracking) mppt tracking

i paid $10 usd for a Hover 1 HoverBoard at a thrift store and it works

I meassured the power of the hoverboard and it draws 8 amps for each motor 16anps × 36v = 575w peak power The maximium motor speed a get is 25km/h no load speed

The one you have is only 250w motor. At the best scenario you'll get close to that not more. Just buy more efficient wind turbines for not so much money. A 500w is much better than the hub motor at converting energy.

I know that thing is heavy, but you lift it with one hand like nothing inside it After I read something in your t-shirt 😅

the graph nicely shows things... jacobs law. and the plateau or limitation of permanent magnets, fixed flux densities... it shows what is available in the LOAD, and only the load. it doesnt show how much power was applied to SPIN the generator. that requires a pivoting mount, torsion arm, and a load cell calibrated to show torque over time... the winding resistance should be close to 40R as well, the peak point on each curve. the same current in the load is flowing in the generator windings. producing heat. as the load resistance drops below the winding resistance, it is the GENERATOR that heats up. short it out. wheres the heat dissipated? solely in the windings. you will find when the load is that perfect "equal resistance" that half the APPLIED power to spin the generator will be available to the load, the other half? its being lost in the generator! as you get higher and higher resistance in the load, less current, you get proportionally more of the power applied appearing as heat in the load, and far less as heat in the generator. but less power is flowing through the COMPLETE circuit. example. a 10KW generator delivering 10KW, full power, requires 20KW to drive it. half the power is in the load, half in the generator. whereas the 10KW generator driving a 1kw load, only needs 1.1KW to drive it... only 1/10th of the power is lost in the generator winding resistance. there is an ideal value for full power, or maximum efficiency. 50/50. half the power in the load, half the power in the generator. there is a specific resistance for the optimum power transfer to the load. and then you get into batteries, and the fact that they arent resistors, need specific voltages to charge, and the current they draw is based on that voltage... it really does not suit the load requirements of a PM based wind turbine. more things to think about is how your rectifiers are interfering with the currents in each separate coil. that is, the BLDC is generally star wound, with no neutral connection, yet the rectifiers are generally wired delta... meaning that the current is shared between two phases that arent equal. you get conflicting EMFs, and losses... if you wire the rectifier so its connected to that neutral point, the efficiency increases dramatically as now each phase is "isolated" and can push its full power through the circuit connected (load) rather than fight a conflicting phase and only deliver the remainder.

If I had 3 hoverboards, I would wire them to a esp and have it collect rock samples from the desert or bring me food from the kitchen...

You can further increase the generated Voltage at lower RPM if you internally separate the 3 phases, use a Voltage doubled rectifier on each phase (2x diode and 2x capacitor) and put the 3 rectified phases in series!
