Thank you for this, I can't believe how horrible this design is from a repairability perspective and how dangerous it is to have everything submersible... But what do I know, I'm just looking for a DIY water pump project and this looked like a horrible design to me 😅
In my own opinion, since the pump uses ac current and ac current has 2 half waves that flows in opposite direction, when the first half wave enters to the first transformer winding, it changes the polarity of the rotor magnet and causes the rotor to spin by 180 degrees. And second AC current half wave enters to second transformer winding, again it changes the polatity of the rotor magnet and spins for another 180 degrees, and it repeats while the pump is still plugged in. I hope i explained it very well, i did my best😂
@@ronron322 thank you. It was a bad idea then for me to have epoxyed it to the magnet-might explain why now, it spins fine, but I have to move it up and down in water to get it to prime. Once I get it running, it stays running, but if I set it on a timer, it won't start pumping by itself.
hi.. i have a waterpump that is similar to urs just that mine is of different name. While i was cleaning it up, i drop it but luckily i manage to pull the cable. However i noticed it made a tear into the black coat exposing the inner lines tho they are not damage. Is it okay if i have to fix it with just shrinkable heat cable/coating? will the water still enter into the wires.. i am afraid of electric shock
Cover it with epoxy that is water resistant. After the epoxy hardened, cover it again with vulcaseal. Wait for atleast 48 hours before using it to be safe.
ah .. di ko po naisip pde pla un.. naghanap akp sa shopee my nakita ako liquid electric tape..kya lang bka tagos pa rin kya gmitan ko din ng vulcaseal.. salamat po sa idea
Pag nasunog na po ang transformer coils ng pump, hindi na po ma repair yan, kailangan nyo na po bumili ng bago. Kadalasan kasi sa ika sisira ng pump ay yung pagka sunog ng transformer coils, tulad sa pump na ito, lalo na kung nababasa sa ulan yung plug ng pump, ma short circuit po yan at masunog ang coils sa loob. Ingatan lang po palagi ang plug ng pump na hindi maulanan para hindi masira ang coils sa loob.
No. It is very dangerous if you attempt to repair it. But you can replace the rotor if is deformed. Deformed rotor can also cause the rpm to slow down. You can purchase it online.
Try nyo muna linisin yung loob ng pump. Pag hindi pa rin gumana, siguro sunog na rin ang coil sa loob at hindi maaring ayusin. Pag nabasa ang sa ulan ang plug ng pump, yan ang kadalasan na dahilan para masunog ang winding ng pump.
kahapon ku lang nilinisan ang loob kahapon ng umaga ko napansin bat ayaw gumagana pero kapag hinawakan ko yung rotor parang gumagalaw kung eh plug pero kung eh unplug di gumalaw
@@personaldata6665 Yes po, maganda yan. Pero kailangan lang talaga nito ng mamahaling inverter, yung pure sine wave talaga, hindi pwede yung square wave or modified square wave na inverters.
Thank you of letting me see the future of fixing my water pump XD
you save me so much time and effort XD XD XD
Thanks for the great effort to share the information.
Welcome.👍👍👍
thanks for the video. saved me time. i was about to dismantle my pump too since it died just recently. ill just keep the impeller and throw the body.

Thank you!
This the only video that dissects the motor gently and shows everything!
What is the electromagnetic centre magnet motor called?
thank you ... very helpful video
👍👍👍
Detailed video,
Good work
Good effort
I like your dremel
Ternyata besar bodynya doang yaa,, Daleman nya kecil trafonya,, 🎉
Thank you for this teardown video. I was always curious to know whats the inside mechanism. Do you know the principle by which it works ?

@@ronron322 were both the transformers connected in series with the power? or only one transformer connected to the power?
@@danalex2991 There are 2 AC wires, each one is connected to the transformers then both ends of the transformer are connected together.
Hi do u know whtas the RPM of this motor or atleast how many poles does it have
, I see so that’s the pump , heheh I misunderstood I thought of something different my gosh kaulaw
Question: is the impeller supposed to have some "play" on the magnet? Loved the vid and gave a LIKE. Thank you.
Yes.

@@PapaMav I think the rotor needs to be replaced.
@@ronron322 by "rotor" which part do you mean my friend?
@@PapaMav the one that spins.

Boss make a vid -how repair a3000 sub pump not working

ok now i know... once spoil just throw it away and get new one... pointless to repair
Is it repairable if the rpm slows down by alot?
No. It is very dangerous if you attempt to repair it. But you can replace the rotor if is deformed. Deformed rotor can also cause the rpm to slow down. You can purchase it online.
@@ronron322 is it "okay" if i hear water inside the rotor comparment? Im still not able to open mine to check the rotor.
@@ronron322 thank you btw, almost forgot 🙏 😄
@@aquillae You should check the rotor inside, that's the usual problem on submersible pumps.
@@ronron322 thank you again 🙏
bat yung A3000 ko di gumagana nung oct 2021 kopalang binily hindi nman yung rotor nasira

@@fishingpet1992 Yung plug try nyo rin linisin, check din po yung power cable kung hindi putol. Try din e saksak sa ibang outlet.
yung plug parang bago billy paren linis yung cable walang putol nung binuksan ko check
nung isang gabi ok gumagana pag dting ng umaga pag sasak ko wala na
boss malakas ba yan sa kuryente?I mean malakas kumain ng kuruente?
Yes po, 40 watts po ito. Around P400 ang babayaran monthly kung gagamitin na walang patayan 24/7.
@@ronron322 okiki boss salamat sa info..
@@ronron322 dapat pala may solar panel para tipid
