I've looked at the uneven winding jobs on many Bafang motors from the factory and wonder how they get away with charging so much. I've thought about rewinding mine, but never saw such a great rewinding job. Thanks for the encouragement. This should be a training video at the Bafang factory 😄👍

Добрый день. Имею очень похожий мотор (Bafang 36V 350W) - в косе 5 жил по 0,5мм диаметром. Пока не разматывал - сколько витков на зубе неясно. Он на заднем колесе 28''. Подскажите какое кол-во витков у вас получилось намотать косами по 10*0,5мм? По диаграмме вроде 7, но лучше спросить... Также, если правильно понимаю, увеличивая количество жил в косе или диаметр жил при сохранении количества витков, уменьшают скорость но увеличивают момент - правильно? А уменьшая количество витков соответственно увеличивают скорость вращения?

I'm having issues with the wires getting caught up by the sharp edges sometimes and curious what their called and how do they work? Confused about after the wire is back in the slot and wrapped around one of the poles how you get the black paper or black film or what ever it is off?

Actually answer is simple. if you reduce the wire length, the resistance is decrase at the same time. it means more electric current flow. and again it means high magnetic field. I would advise increase the battery power instead of reducing the wire lenght. if you increase the magnetic field on the wire then you have to increase the neodmiyum magnets's magenetic field. these both balance between wire and magnets have to increase or decrease at the same ratio. Otherwise you will lose effiency.

@@buddha2845 I used 10x0,5mm,cross section S=πr²=3.14x0.25²=0.196mm²x10=1.96mm² If wire 1mm,S=3.14x0.5²=0.785mm²x3=2.35mm² So I need 1mm 3 wires for each slot and the performance is the same.Only 1mm is hard to wind and will hardly fit.

Bonjour J'ai trouvé dans votre vidéo le schema de bobinage pour moteur Ebike 18 poles tres interressant aussi je voudrai savoir la longueur de fil utilisé pour bobiner un moteur (a peu pres ) moi c'est un moteur de 250 Watt 36 volts Dia fil 0.6 mm. Je voudrai savoir aussi le sens de rotation. Merci d'avance pour les infos DIDIER P

I don't remember the length of the wire. You can easily calculate the length yourself. The direction of rotation is easily changed by swapping any two phases of the controller.
Why not just increase the voltage instead of doing all this work?

Thanks for the observation. The voltage of the motor is 36V and has already been increased to 48V.

its not a magnet. if you can, you can make one using a dremel and a hardened steel bit but safety first and only if you know what you're doing

Ответ в коротком описании видео.Чтоб было яснее,добавлю-этот мотор был расчитан для 20"колеса,я буду использовать в 12"колесе.Если ничего неделать,то уменьшится линейная скорость колеса.Чтобы такого непроизошло,надо повышать обороты мотора,а на это только два способа-поднять питающее напряжение или перемотать мотор с меньшим количеством витков.Я выбрал полседний вариант.
