Brushless outrunner motors are the working horse of RC hobby. They power everything now: drones, airplanes, cars, boats. And from time to time they just burn. You can buy a new one, they are not that expensive, but you can also rewind them.
To rewind brushless outunner motor winded in dLRK (95% of cases?) you only need 3 things: motor, wire and time. And a knowledge how to do it.
In this video I show how brushless outrunner motor looks like inside, 12n14P (12 coils, 14 magnets), present dLRK winding schema and two possible ways to terminate phases: Delta and WYE (Star).

hey, I have READY TO SKY 2212 1000Kv 3s Motor how I rewind it to run on 12s battery?

@techfact2684 6 дней назад

Thank you so much. I have a motor.. a unique motor of a costumer. And practically it is different but theory was same as your motor. You helped me alot.

@GUILLERMOJGARZON 5 лет назад

Thanks so much for sharing your knowledge. Very well explained on the 3 video tutorials.

@mintudoku9375 5 лет назад

Clear enough to understand... i think with this clear teaching i can make one too.....

@chrisflint6479 3 года назад

Very well described to get to Star snd Delta.

@hamzaarshad861 5 лет назад

exactly what i was looking to understand ...thankyou

8:27 how would this diagram look like for 9n12p motors?

@abimaputra 5 лет назад

Dear sir. This is very useful vlog. Very good. ;) so....how to mod the rewind of 2300 kv motor so they can perform better for the race...yes of course for adding some thrust and running 4s. I want to push them for their optimum performance? Is it possible?

Very understandable video these type can you upload all types of motor submersible Mixy washing machine 3 stage speed motor such as table fan etc..

Mam uszkodzony taki silnik bezszczotkowy. Dwa zwoje są przepalone. Nowy b.drogi. Czy da się nawiąnąć taki nowy zwój znając srednicę drutu i ilość pętli?

@alexnyk1994 Год назад

How the magnets are arranged? N/S? OR ALL FACING N?

@FPVUniversity Год назад

S/N/S/N

@yousifesmail954 6 лет назад

Thanks for this intrusive video , my question is the number of magnetic is 14 are it is constant for this motor or we cane increase and decrease it what is the effects best wishes

@FPVUniversity 6 лет назад

yousif esmail no you can not just increase or decrease. There is limited number of valid combinations on number of coils and magnets.

@thienvu4503 4 года назад

what are about 36 poles wiring ?

@wongsorc6918 3 года назад

hii, how to determine to make our rewinded motor can get 4S or event 5S Lipo support..?

@FPVUniversity 3 года назад

By testing probably. I mean you can compute power under load and heat dispassion but the best way is just to test it

@gatyi28 5 лет назад

Man i was looking for this simple explanation long Time. Thanks Alot. How about the magnet. N,S,N,S,N.... but how to arrange them ? Coil to cover every magnet or ?

@FPVUniversity 5 лет назад

12 coils, 14 magnets. And yes, magnets got N S N S in a circle

@h2o-fpv623 4 года назад

Thank u for this video but I got a question it's not that easy to wind it are the wire are coated?

@xnoreq 4 года назад

The insulation is just a very thin and flexible layer so it doesn't really make it harder to wind. For example, a 0.3mm magnet wire I found has 0.02 - 0.03mm insulation thickness in its specifications.

@pioschannel43 6 лет назад

There is modified dLRK winding method, that gives phase wires in pairs for delta connections. See here: rcexplorer.se/wp-content/uploads/2012/09/mororrewind.gif

@johnmurphy5883 6 лет назад

not always 12 teeth and 14 magnets on an outrunner. there are many other combinations

@FPVUniversity 6 лет назад

let's just say this covers all 220x and 230x cases.

@permanderyadav8826 6 лет назад

How can we bind a 48v 1000w bldc motor for scooter that can run near about 60km/h (mainly my question is about coil binding just like coil binding wire size and how many rounds should be of wire in a coil)

@tyronerai9865 3 года назад

After winding my bldc. It gets hot an burn

@FPVUniversity 3 года назад

That means you either have a short between coils or you connected coils in a wrong order

You ask yourself why use a large rope without using many small strings

@CorruptName1 4 года назад

7:52 You got the second part of phase B wrong. It should have been CCW, CW. Not CW, CCW.

@rebelsfpv8846 4 года назад

Why?

@hamzaarshad861 5 лет назад

im guessing this is a DC motor?

@FPVUniversity 5 лет назад

yes

@FPVUniversity 5 лет назад

or rather not. This is a 3 phase AC motor, only the ESC is powered by DC

@edvinassarulis7526 5 лет назад

Actually it's BL (Brush Less) DC motor

@LokiOdinson 5 лет назад

The details are hidden in the fact that the freaking Chinese never follow the technical specifications. And even if a triangle (delta) (T) is declared on the passport, inside there will be a star (wye) (Y). After all, sometimes you want to save money, and buy a motor for more HF and simply slow it down by reworking it from a delta to a star.

@peta1001 4 года назад

Pawel, nice video. However, I think you mixed the facts. The number of coils (poles) affects the speed... not the number of turns in a coil. The motor speed is proportional to the number of coils/poles and the voltage frequency. Multiple conductors solution (instead of one thick conductor) is usually chosen because the electricity actually runs on/through the conductor surface (not the core). Therefore, multiple conductors can sustain more current and thereby produce stronger electromagnetic field. Other than that, you are mostly right.
