My first experience with rewinding a motor armature

In this video I decided to show my first experience with rewinding a faulty motor armature of an old 1994 drill.After disassembling the drill I took the winding data from the armature (winding pitch, stacking direction, number of turns of wire in the coil, its diameter), and determined from which lamella of collector and armature groove the winding begins. In the video I will show the winding diagram and the order in which the coils are stacked. After removing the coils from the armature it turned out that the insulating gaskets melted and the collector was in disrepair because of the high temperature. I made the gaskets from fiberglass on my CNC milling machine and took a used manifold from another defective armature. Almost all the dimensions of the manifolds matched except for the outside diameter, the new manifold was 1.5 mm smaller. I decided that this should not interfere with the motor. After rewinding I did the static balancing of the armature. At the end of the video you will see what the result is.

for the arcing, might recquire more undercutting on the commutator if its the old style with mica spacers

but long sparks usually points to the motor wires beeing short somewhere

Hi. had the same problem on rewinding 2 vaccum cleaner motors. 1- Commutator lost its quality and at 50 volts and above caused short circuit and spark. 2- Isolation liquid didn,t dry well. 3- didn,t balance well. Thank you

wow amazing job. But it's so much work to rewind a burnt out motor. I had couple of tools (garden weed wacker, electric chain saw) suddenly fail due to burnt out motor. But the problem is more design of the tool which does not keep active ventilating motor to cool it even when tool is not running to prevent motor burn out. Perhaps it's much easier to add small electric fan to keep running when the tool is plugged in to keep motor from burning out.

Thank you. Poor cooling is only one of the possible problems. I think it's rare in power tools. But for example, on my lathe I removed the motor protection and installed a fan for cooling. Without a fan, the temperature could rise to 100 degrees Celsius or even more; with the fan turned on, it doesn’t even reach 70. As a rule, it stays in the range of 45-55 degrees.

Use uma perda phomes enquanto o rotor estiver em movimento vai retificar melhor o coletor e diminuir o centelhamento. O bom é favzer uma revisão com o relógio comoarador no coletor, as vezes por mais que de o passe certinho ele pode sair de centro na hora do funcionamento do torno.

Obrigado pelo seu comentário. Eu entendi porque houve uma faísca. A âncora já foi rebobinada antes. E a direção do enrolamento das bobinas foi escolhida incorretamente. E eu copiei esse erro.

Центровку якоря нужно было делать после проточки коллектора.

Попробуйте поменять провода на щётках местами, направление вращения изменится, возможно искрение уйдёт.

@valsworkshop 10 ай бұрын

Я уже разобрался - дрель кто-то перематывал ранее и сделал ошибку в схеме намотки, а я скопировал схему. Провода на щетках пробовал местами менять, но к сожалению искрение остается.

@@valsworkshop в данном формате я не могу выложить правильную схему, но попробую объяснить. По вашей схеме надо начинать с ламели 3 и двигаться в сторону 2, а затем и ламели 1, и т.д

Это у вас дрель ИЭ1035, мотор крутится не в ту сторону. Вы ошиблись в схеме намотки. Начала и концы секций поменяны местами. И балансировка у вас статическая, а нужна динамическая.

@valsworkshop 10 ай бұрын

Про балансировку верно - буду делать станок для динамической балансировки.

Acho que você errou no teste do coletor deveria testar as lâminas separadamente fora do i nduzido duas lâminas por vez ,as vezes uma lâminas pode está dando co tato com outra isto não pode acontecer e fatal ,isto representa curto no coletor ,quando colocar usado texte as lâminas pra ver se uma não dá contato com a autora lâmina,blza.

Ok your video is good I don't think this is the first time you do this but its ok . However . You dont show how you obtain your data on wire gage amount of turns or were you got it from. You just jump and hack it out means you got the data from technical book .and also you dont have to re balance the armature if you mark were the original last and first windings are and rewind it the same place it will end up the same .The late work on the contactor is completely useless and a waste of strength on the thickness you need to use a very fine sand paper just to clean taking is little is posible out of the contactor material otherwise it will get burned on the first worm up copper is great conductor but not to good resistant to heat .the success of a DIY Video is base on the idea the others can do it to and got the same results otherwise is just a high ego video

You may not believe it, but this is really my first experience of rewinding an anchor. And if you watched the video to the end, you saw that it was unsuccessful.

@MrRacerhacker 2 ай бұрын

Dont need books, just common sense, just count the windings, if you need more power sure you can go up, but if just replacing a motor in a drill no need, just copy what you see, wire gauge can be measured with a caliper, but rule of thump think 4amps per mm2 copper, id would say this is just a home video, armature needs rebalancing anyways since you are adding new varnish witch changes the weight
