From Zero to Hero I Created a CUSTOM Brushless Motor in 1 Week!

[@OmegaKillerArtMeisterSkywalker]

Would have loved to see a test of the motor too, but definitely enjoyed seeing the design process.

[@lanchesternaanyane]

Finally someone designing in Blender in a way I can understand

[@shoumikahmed6373]

For efficiency and higher torque you should use arc neodymium magnet so the gap between rotor and stator stay consistent.

[@KeepoHdee]

Odd choice to use Blender for this application as opposed to Fusion or Autocad. I dabbled in Blender when I was younger but mainly used it for artistic/organic designs using surface modeling techniques. I use Fusion 360 these days, I found it much easier for parametric modeling

[@paco3447]

You can use FreeCad 1.x also (or Ondsel), as long as got huge improvements and better UI than previous versions. An axial flux motor would be great as a next project.

[@dempa3]

Very interesting video! I'd be very interested in how to design the configuration of the brushless motor. How do I design for a specific target power, rpm, torque, kV, etc. How does the amount of pole pairs affect the result? The amount of windings and the thickness of the copper wire? How does one choose the permanent magnets? How does the Y and Delta configuration differ? There are many aspects which go into this, and I hope that you'll make videos on these subjects, because you are good at explaining difficult things in a way, which is accessible for a wide audience!

[@ELECTRONOOBS]

@@dempa3 that includes a lot of calculations and more specific: to know the materials. In a motor, the material of the core is very important

[@dempa3]

Then I suppose there is the discussion of materials in the motor that needs to be added to the list! 😂 Jokes aside, I understand that such videos are a big project. But one can dream :)

[@axellno1759]

It would've been nice to see if ... and how it works. :D

[@JasonCummer]

ah! what are the RPMs? torque? power? Anything. We NEEDS the deets! Anyway with less intensity. Thanks, That was cool to see :)

[@HaloWolf102]

I too currently have Blender 2.79, a great and perfectly usable version of Blender. However, you should download the newest version of Blender. Not to replace it, but to practice. It doesn't impede your computer and work flow as much as you might think. My friend pushed me to learn the new version, and I'm glad I did. There are just too many add-ons I have downloaded that are useful, and I don't want to leave them behind. But in that same vein, 'I' don't want to be left behind. So I practice in Blender 4.1. It's funny because some of the features are still useful in 2.79. I will transfer models between the two versions from time to time.

[@U_Geek]

I'm a blender glazer, no better way to put. I use it for image editting and remixing stls. But for straight up CAD it's horrendous, from my experience you pretty much have to nail the part perfectly from the beginning because certain things are almost if not completely impossible to modify afterwards, so my hat is off to you for having the patience to actually use it to make stuff especially that swashplate that you made a few videos ago. Also, any reason to not try newer blender versions? You can import your preferences so not like you have to re learn the controls. Beyond that it's oretty similar to 2.7, but I guess you already tried just curious which parts of 2.7 do you prefer. For me that version hold nostalgic value but not much more as I started using it in 2.7.

[@U_Geek]

Ok continued watching(sorry for commentimg early). The thing you do with scaling to test fits is unnecesarry. Instead of percentages you should you constant mm offsets, those tend to stay the same for a given printer, so if you learn that your round holes need to have .1mm smaller radius for a good fit then you can reuse that later. I modelled multiple parts based on old measurements like that, if you do that that might save a lot of time.

[@Zimbob2424]

Wow, I see you haven't upgraded Blender in awhile, I used too wait myself, but now I constantly upgrade because it is growing so fast in so many directions that you will be lost when you have no choice but to up grade. I also use cad sketcher which you would probably like, it's a nice addition for modeling working parts. I like the idea of color changing for different parts. I will start implementing that. Tolerances I test with every project and part since settings get changed for strength on some parts so that can also have an effect that and different materials. good job on the design

[@ya_begitu_lah]

Sir, try making an axial flux dynamo and try making it with 10 stacks

[@shorecreature]

I use blender too for technical prints in much the same way for many years. Haven't tried anything else and don't want to. As you said, re-learning what already works can be difficult ... especially when that time can be put on another project. But any new users, I would also advise to use a proper cad program.

[@АндрейМихайлов-о6я3ц]

I was waiting for the whole video for the author to drop the blender and go study CAD. But he is strong! He got to the end. Although the strongest people do it in SketchUp. And Chuck Norris does it in Paint.

[@zakariakhamees]

This design is very similar to the MakeSea bldc motor by Christoph Laimer. I would recommend its build page if you are interested in learning how to build one in detail.

[@abu-zaiter]

I m working on a simple controller based on atmega88 and IR2101 as IGBT 48volts power now my bike can run up to 35 km/h is good ??or should run more than this speed??mosfets looks cold

[@oires]

It would be much more interesting and powerful to see a 3D printed brushless motor built from a metal stator salvaged from a universal motor and adding efficiency enhancing parts like a flux ring.

[@ScottieD369]

PS You still never answered my question on that previous project. Anyways Glad you have tons of projects keep them coming.

[@wikovisser3664]

You should understand Fusion360 in no time. It is much more optimised for mechanical designing. A new world of possibilities will open for you. Never stop learning.👍

[@dukejer3073]

I want to see a brushless with no permanent magnets PCB motor in the future that uses some kinda of exciter to induce the magnetism on the rotor. Hopefully someone develops one in the future. A complete PCB motor solution with some bearings and no magnets.

[@michaelwilson9557]

If it's brushless, how do you induce a current in the rotor. Only way is to use A/C induction motor, otherwise it's just a brushed universal motor.

[@dukejer3073]

@@michaelwilson9557 I was thinking using some kind of exciter coils that are picked up by a receiving coil on the rotor and converted to DC using a rectifier on the rotor and used to power electromagnets. Similar to some alternators. kzbin.info/www/bejne/oHjHdKSJrdmHnNE

[@michaelwilson9557]

@@dukejer3073 These types of alternators can be converted to motors fairly easily, but the problem is they have low efficiency.

[@dukejer3073]

@@michaelwilson9557 I am not looking at converting these alternators to motors. I was just wondering why this same technology could not be used on a small PCB to power electromagnets on the rotor. Using exciter circuits to generate DC in an electromagnet on the rotor without using permanent magnets. It could really reduce the cost of a small motor using PCBs.

[@michaelwilson9557]

@@dukejer3073 Yeah I got that. I was just trying to think of why it's not more widely used, and I think it's low efficiency, but the efficency problems may be due to the fact these motors are "dumb", with no controller logic. The idea is worth taking a look at.

[@benmaynard3059]

Shweet cool ✌

[@martonlerant5672]

Using those screws to hold onto the part by grabbing onto it with friction is a bad idea if you are using PLA. As its VERY prone to creep under constant load at room temperature. Securing the metal rod with screw thats going through a hole in it, or using glue is the way to secure it, if you want the thing to last.

[@ELECTRONOOBS]

@@martonlerant5672 thanks for such great tips

[@Enigma758]

Very impressive that you designed and built your own BLDC motor! One question though, shouldn't the inner sleeve of the ball bearing make a tight fit against the shaft, since it's the ball bearing race that actually moves?

[@ELECTRONOOBS]

the shaft is 5mm and the inner ring of the bearing is the same. You don't need it tighter than that...

[@Enigma758]

@@ELECTRONOOBS I think it should be OK as long as the shaft doesn't rotate within in the inner ring.

It's a shame you you could not laser cut thin sheets of Iron to make the core. But have you thought of making a 3D printed mould to make the core out of resin impregnated with iron powder? Writing this, another thought came to me. Could you impregnate resin used in a resin printer with iron powder? then you could print the iron core?

Is the resin printer canceled?

Plastic motors are not good because their efficiency is very low. They must be made of iron. In addition they heat and melt the plastic.

Please make an axial flux motor it's always beyond reach to the public.since it's most powerful and compact it's way too costlier to buy and not available as easy as bldc radial flux motor.

Blender looks like it makes mechanical assemblies a pain in the butt. It is worth learning a new program as with mechanical assemblies you can constrain everything far better than in blender. Not to mention patterns and whatnot that would have made arranging the magnets far easier.
