This is very interesting. I’m anxiously awaiting to learn about rewinding the motor. I had some students (I teach a STEM RC Aeronautics class), who accidentally used screws that were too long and shorted out the motor. I’ve kept the motor, in hopes of some day learning (and eventually teach my students) how to fix the problem (and learn a little bit about electronics and motors). Could you also possibly go over how to correct/fix a bad/shorted motor? Thank you for creating great content.
I used to do this, back in the day, with great success. What I used to do was... I removed the stator from the metal base & circuit board (& replace it with my own motor mounts); rewound the stator; put two bearings down the center of the stator; re-fit the bell & I'd have a better motor. At one point, I went as far as replacing the magnets (called the "flux ring") inside the bell housing with decent NdFeB magnets. I had used those motors on some indoor foamy planes that I had built from 2008~2011.
Seeing you perform those initial rotational speed tests--with the plastic CD disc, got me thinking/'imagining'... What 'IF'--someone was able to carefully cut-out & relieve the outline of wedges, or 'arc sectors' of a CD disk, in a radial pattern...such that the freed, polycarbonate plastic could be bent/leveraged with heat, into the blades of a fan. Or, more accurately like a turbine/turbofan 'Blisk'? Could several of these be mounted in series on a shaft, with slightly different 'pitch' blades--so that when rotating they pass air like a series of fan compressor blades?
Those windings look pretty good actually; very much like any small airplane motor. The main factor that is preventing this motor from performing as well is the relatively weak ferrite magnets in the bell. BTW, cell count has nothing to do with battery weight. You can get 3S packs that weigh less than 2S.
@@Joyplanes Oh I know! Don't you just hate that? I have also spent much time trying to extract and replace hair dryer motors with brushless to make edfs and often find it's near impossible to disassemble them non-destructively. The few I have succeeded with work beautifully for that purpose though Old HDD's also usually have crazy strong magnets in them which I always try to save. Don't give up and be sure to search youtube for tips and tricks for salvage tips and tricks. ;)
There are a few thing wrog with your test. Rewinding it is the only way because it is rewinded from the factory for low assumption and low power. You could for example rewind it for a 4 sell. On rcgroups you find how too. the secondly choicing a prop for your motor is a know how that you have to learn. you can not just throw a prop on your plane so you will burn the esc or the motor or all of them together( believe me not a good felling) but I learned many years ago and I am shore you will too :). I used too rewind nearly all my of motors my self
Re-wind the copper wire with thicker gauge wire and do a star configuration winding and change the magnets with neodymium magnets that will definitely give you alot of power and definitely wish to see that video.
I though the thinner gauge wire can make rotation more faster than the thick gauge wire, correct me if I am wrong. I need some more research on current flow of a wire.
Keep searching different drives for better motors. I've used many to successfully fly 3 foot flying wings with a 5x4 pusher prop and with very good performance. If you want to use a larger prop, you need to replace the magnets with neodymium and rewind the coils.
I have some of theses motors. The one you have has a weaker magnetic belt. Look for the grey ones they are stronger. And you can increase the power just by changing the wiring. I saw someone getting about 120 grams of thrust without changing the magnets.
Hello friend, I have two questions: 1) Is the CD Rom engine cover really difficult to remove? I apply a lot of force but it doesn't come out. 2) How to remove the short motor shaft to replace it with a longer one? Thanks
Great video DIY CD motor into small airplane ✈️ niceeee!!! But I wondered if you know what's this motor's KV is it?? Cuz I see you was using 3s at 850, at 35c zippy xt30 cord battery, so I wondered what is the CD motor for KV's number, do you now, please do lemme know, thank you dude!! Cuz maybe you could do like 100c 850mAh, 3s with xt30 cord battery, maybe you could fly little more longer cuz 35c is pretty low on throttle and pitch for speed power... Awesome footage by the way! 🤙🏼
Is using an dvd motor with only 3 copper pillars inside good for rc plane? Its our school project and im designing one that is ultra light , small and sleek the plane was made out of styrofoam with a wingspan of 2 rulers. And abiut 1 ruler fuselage lenght.. im currently making it glide first so that im nit gonna problem the flying when i added the control surfaces and motors..
@@daviddavids2884 It can be less mass because an electronic print can be lighter than an accu. You are right about the energy. Depends what is needed for the set goal. High currents during shorter times is maybe all you need. Lipo can give high Amps
@@Joyplanes They're shrunk-fit in the drive housing. Remove the platters, place the motor upside down and support the drive housing with something so that the motor axis is free from the underground. Then and use a hammer and a punch to tap on the shaft, driving it out. I liberated a motor from a Western Digital drive this way, yesterday.
Who wants the video about rewinding the brushless motors?
Yooo!!!
Meeeee

REWIND TIME!

Sure. That's a pretty common mistake with the screws. I'll be covering the fixing of a business motor including rewinding.

I would like to try with Hard Drive motors but the one I had is difficult to get the motor from, I'll try to get more old ones to try that.

better buy a rc motor

i got my motor from blue ray, it's big, on 6s it spins veeeery fast. i wanted to test it on glider, but i blew it with too much load
😂

Pretty nice, dude! 😃
Maybe with a 4s battery and a 7 inch propeller? There's a great one from Dal Prop, I think its name is T7056C. 😊
I need to try with a very small 4S battery since the ones I have are 1000mAh and are heavy for this airplane.
Thank you sir for making English version of this video.no offense to latin brothers and sisters..
I have some of theses motors. The one you have has a weaker magnetic belt. Look for the grey ones they are stronger. And you can increase the power just by changing the wiring. I saw someone getting about 120 grams of thrust without changing the magnets.
I felt wind to my face, when watched how fast motor spins.
Did you try one from the hard drive ? It's far better quality/precision. It's made to turn a lot faster.
They often don't have enough poles on the stator to divide evenly by 3. Sometimes you get lucky.
@@robwallis1277 Yes, I know people have driven some of them with a normal ESC
You could try to use that motor on a very simple foamboard plane if you peel the paper off on the foamboard and use carbon fiber reinforcements
Cool.
Nice hobby
Take two similar drive engines and mount their stator on a shaft with the prop together. The bell must also easily replaced
Can i make Gimbal stabiliser using cd rom motor or hdd motor?
Creative 80 you could if u add a cheap flight controller which stables it
Tienes dos canales
Yes, this is the English one.
How about using HDD motor? It might be more powerful.
I've explored this option and HD motors are generally even smaller. Larger motors can be found in old tape backup drives and they work great.
Hard drive motors don't always have poles in groups of 3, making it hard to convert.

How do you prevent the bell from being pulled out of the motor by the propeller?
i wil look to your next video i have a broken motor with on wire broken so then i can re wind it with new wires
I'll do that video in few weeks.

Hi, you better off buying the proper RC motors since they are not very expensive and you'll save a lot of time.
Is that all you need, connecting an ESC to the wires?
you should use hardisk motor
Maybe you should make an helicopter out of that thing!
Hello you are cool
You can try with a boost converter and a single cell lipo
1) adds MASS to a model. 2) when volts are increased, AMPS Will be Decreased. and WATTS stay the Same.
@@daviddavids2884 It can be less mass because an electronic print can be lighter than an accu. You are right about the energy. Depends what is needed for the set goal. High currents during shorter times is maybe all you need. Lipo can give high Amps
Ok but u havent mention where u can get the lil blue controler the makes it slow down & speed up
You can replace its magnet to neodymium magnets.
which propeller was better for the label engine in your tests? I would like to try it too, I don't know which propeller to use.
What if we replace magnetic with multiple neomedeum magnets
I watch the two videos the spanish and this
Cool!
can i run this motor with regular 2 wires adapter + and - only?? and how does the wiring go in this case ?
A good brushless motor from an computer is from the hard drive disk..... Much more powerful
I've tried to get one but it was embedded into the hard drive case. I'll try another time.
@@Joyplanes OK keep on being creative, great video's

Where is rewinding video??🤔
Ok, I'll be doing one soon
It good idea
bro can i change its shaft //
You can make jet engine with this motor
How ?!
Please tell me how I can get ESC
You haven't done a rewinding video of that DVD BLDC yet!!
I have one !and I need it to run at max speed to create sufficient thrust!!
You told that you will be doing it in upcoming video!!
@@farazsid4270 Hahaha yes and I never did, I'll do it some day.
How did you know what esc to use?
Any ESC will work because the motor is not too powerful.
Could I use a 10 amp ESC?
@@yangexue6596 Yes, that should be more than enough.
