How to Diagnose Repair and Maintenance BLDC Hub Motor ( HALL SENSOR REPLACEMENT ) 

Most knowledge I’ve ever gotten in 20 minutes. Thank you 👍

Great job! Probably the best and most inclusive explanation of hall effect sensors and physical take apart of a motor that I have seen on RU-vid. I have watched plenty of videos about 35 in all. I also have an associates degree in electrical and could not teach as well as you. I would recommend your video to all who want to attempt to repair their ebikes. These are only now becoming very popular in the U.S. probably due in at least part to the high increase in gas prices. Again thanks for an excellent video.

Thank you for sharing your knowledge and experience. Well presented. Don't stop sharing.

Just love that you have lead acid cells and bike stands! Finally found a use for them!

Super video, clearly explained about hall sensor function, problem detection and testing hall sensor fault using multimeter.👏👍🙏

omg...thanks alot. think as a mechanic im gonna try fix my wifes motor instead of buying a new . thanks a whole lot

OMG seriously you are AWESOME, ....right now i was to affraight to open.... and i was looking exactoly for a video like this. also the testing with putting the cables together is great ! Your Video takes the fear of opening away, becourse you show step by step what you do !!! I have only to replace the small teeth-wheeels cause a few broke out, but know i know how to do THANK YOU I own 2 geared enginges and on direct drive one. for the later i always have to move a little backward before the throttle works, thats somehow strange?!, ....that was my intention searching ...and finding your video. .... cause i guessed somethings wrong with the hall sensors!??? It is super strange to roll back before i can use the engine, ....but after releasing the throotle i cant use it again, ...i have to stop ....and start again by rolling backwards a few centimeters!??? so no acceleration while driving, after release once. ...never had this before!? Do you had this problem before???

Thank you for this awesome video. You are a master. If you make a future video, please talk a little about your background and how you were able to figure all of this out.

Don't stop sharing these helpful video`s ! , thank u and thumbs up!!!

Grazie, finalmente un video istruttivo!

Thank you very much for your video, finally i can fix the problem on one of our blddc motor on DIY buggy. Because I already know how and where to look for the problem.

Very good video. Thank you for sharing your knowledge. It's very useful. My 250w motor can run with no load (run when on the kickstand) but when running on the road, motor cannot run. I will use your guide to check the motor.

Good stuff, you got the yellow connected..!

I like alot your expanation, save me for buying new motor

Hi sir very well explained. And rectifying of the fault.

Thank you for your detailed video

Great, simply and easy, thank you very much

This was really good, thanks!

Excellent video thank you so much for sharing your knowledge ❤😊

Great troubleshooting video, Thanks so much.

Which hall sensor we should use ? Thanks for this usefull video !!

Keep this up. Very helpful. Thank you

U r the ebike number one👍👍

Thank you for this video! Subscribed

That's great technician very good 😅

YOU helped me big time!!! Thanks.

THANKS FOR VERY GOOD VIDEO NICE AND SLOW EASY TO FOLLOW

Thank you. I just bought a broken ebike for $200 fro local tip shop and had just checked through everything out as a previous owner had broken and lost part trying to fix. My bike sounds exactly like this one and I thought hall sensor. So I'll be doing all these tests and strip down the motor. At worst I have a nice bike. At best I have a newish folding ebike I can carry around in my car or van.

Thank you.your video excellent .

Thank you!

nice video tutorial..thanks for sharing the knowledge🙏

Great knowledge my friend nice video. I think in the UK would be be cheaper to buy new one as its involving lots working hours. But great information and if the motor in mine I would definitely fix it myself. 👍

Great video just what I have been searching for. Thanks for posting! Subscribed...

complmenti davvero bravo.

You are legend!!!

Hii Sir. Can we upgrade a 48v 250w Hub motor to 48v 750w motor by changing the windings? If yes please help me sir

Excellent vid, thank you! what kind of grease do you use? worried some petroleum based greases could affect the nylon gears... Also, wise to note any wear on the shafts or worn bearings could cause rubbing and damage to hall sensors, no? have you seen this? I did a Gio Italia hall sensor and one bearing was a little sloppier than new, i was wondering if that caused the hall sensor to rub on something. What else causes hall sensors to fail? solid state should be super rare but yet it is common

Superb content

That moment when you sway to the right with your mouse to subscribe but.. I am already subscribed... Noice!!! 🤣

My 1600w motor feals like a 250w on take off but reaches 36mph. I cleaned the magnets. And replaced all 3 phase wires the were cracked and didn't look good. Now I have done your test pos to ground. Yellow .614 green .617 blue .614 if I go pos to pos all 3 wires show .OL does this mean even though the motor works sort of that the all sensors are bad?

Tanks ❤

Question. My motor has resistance equally in both directions with all 3 wire shorting tests. Is resistance only suppose to be in one direction during first two tests?

Gracias campeón 😊😊😊

you are awesome

Άψογος/αναλυτικός με λεπτομέρεια όπως σε όλα τα videakia :) Μια ερώτηση, άλλαξα sensor σε ένα hub motor μετρώντας όπως στο videaki , εκεί που εμφάνιζε μηδέν η πράσινη φάση τώρα βγάζει τιμές αλλά με μικρή απόκλιση από τις άλλες 2 που λειτουργούσαν. Υπάρχει κάποιο πρόβλημα με αυτό ? O παλιός sensor ήταν 71F όπως και ο νέος που έβαλα. Ευχαριστώ !

hi, excellent video, how can I test the controller??

Nice work

Very good video, can i just use the 3 wire without hall sensor?

Best video thanks

Thanks for the video great helpful 👍 I got same issue but I can't find same model number hall sensor.😢

are hall sensors problems always noisy? And do they ever fix themselves so it only happens intermittently? these are my main question and hoping you have the experience to answer that. Much appreciation !!!! My electric scooter with dual brushless motors (silent. 1. I think it is getting worse. I think it more happens when it is warm on a warmer day (after the first ride if i take that ride in cool morning then it does not happen until the day warms up on the second ride). 2. It only happens in dual mode, not in single mode. on dual mode it is asking for full current to both wheels. 3. The motors quite when I reach full throttle. They cut out on the top of the throttle If I describe the thumb throttle like half an analog clock where 12 is not pressing throttle and 6 is full throttle. the bike only works from not pressing (12) "0" to 5 once i reach near 4:30 or 5 oclock on the dial, its totally dead and no noise. just cuts off all power and Im coasting without power. So it does not work on the most depressed part of the throttle. but also sometimes if I gun it from start to full throttle it will die sooner like 3pm on the dial. When I say cut off, Both motors cut off. 4. Once it cuts off even when releasing the throttle the motor will not reengage unless I first back all the way down to 0 . 5. and one more thing. I have an extra thumb speed controller with speedometer and all settings working. so i replaced that and that did not solve the problem. Any thoughts on this. what should i be looking for. Im pretty techy and will take apart and fix most anything myself. Im wondering either this relates to the front motor, or the front controller, or the controllers communicating together, or something is cutting off when scooter is trying to pull full power. A battery short or something in the BMS? (since there are two controllers in the nanrobot one for each hub wheel and they are wired to communicate together). Could it be the hall sensors in the front motor?

Damnn nice video bro!

Good my friend.

Realy. Greater

Insanely helpful video. Can I ask you a question? Why does the hall sensor only show output while spinning the motor in the opposite direction? Shouldn't it show the response in both directions?

Great! But seriously, the video got interrupted by 6 different ad breaks!

gracias voy a desarmar el motor y cambiar el sensor hall el de color azul que a mi motor esta con fallas🚲

Brilliant !!

Thanks, very educating! I have a "stupid" question. I hit on the video for the thumbnail showing the rear wheel. I was looking for days for this type of bike with this kickstand. After 2 years taken apart, I put my old beloved bike together. I have to change a mosfet, but the major problem the KICKSTAND. It keeps falling off and I feel stupid. It is the same as yours and I fixed as yours. The only difference that you have a large hole to place it on, mine is an open U shape. Q: Do you have any spring under the srew? Can you suggest some solution? On the piece, where the screw tighten, there is deep cut, seems for stabilization. An inch long and maybe a quarter wide, but in the box I didn't find anything to fit there, nor in my memories. Should I use double screw? There was one in the box fitting the size. I know it stupid, but it is great discomfort without a kickstand.😊

谢谢你的视频分享。👍❤️

Great video. Question…does it matter if the hall sensor replacement is unipolar or bipolar? Can’t find any information online or on RU-vid. /Bklyn👑

Hello at ev-customs, is it possible, I could get my Scooter in for a wiring sort, tidy. If o.k.where do I sent to. Thank you.

Great video! What setting is the multimeter on for the test at 9:17? And is it done without power?!? Thank you!

Hello from scotland thank you for the video , I had to replace a hall sensor following your steps , it worked great for 1 hour , now my wheel keeps looking power , I checked hall sensors again but they are fine , I checked mosfets in controller , it's also fine . I can hear a high pitched noise coming from controller . Not sure if that's normal . Any suggestions ?

Hello, this video is interesting, and may have some advice on my ebike. I have an Ebikeling Waterproof 1200w Rear Hub motor kit 48v. My problem is that my rear hub is not working? I have tried different things. There is power on my LCD, but there are no error codes? I have tried it with x2 different controllers, x2 different throttles, and have full power on my battery? there is enought charge on the battery, and I know that the current is flowing. I hear a click on my rear hub once powerd on, but not sure how come it is not working? Rear hub is brand new, never been exposed to any outside elements? Does the gauge of the wire play a role in this? Becasue my battery is a Dorado type battery that sinks into the frame. The gauge that came with the battery connector is how ever thicker than the one that is attached to my waterproof controller. It goes from an Xt60connector into a Anderson connector. Do you think that its the wires or maybe hall sensor issue? Your advice would be much appreciated thank you!

Sir if i may ask,what could be the problem of my electric bike,when i turn the throttle on full speed the power suddenly shut down and i need to turn off the ignition first then restart it and the problem repeat it self many times,i can't even enjoy riding it now

Thanks I like it

WHAT ABOUT TEMPERATURE SENSOR BECAUSE MY MOTOR ARRIVES ON 12 KM PAR HOUR AND STOP INSTANTLY I WANT TO KNOW THE REASON

Hi sorry I'm new to electronics , when your testing volts on the meter , do you need the ebike battery connected and turned on ? Thanks for the video

The value of my defective transistor was unreadable, is it possible to replace it with different hall transistor? If thats so how can i determine if the one I buy is compatible with my other hall transistor..I have 48v 15a controller and 500w hub motor..thank you..

Greetings. I am looking for (3) H141 00A1 transistors, which went bad in my hub motor. Any suggestions on who sells them in the US or anywhere? I went through many sites and negative. It is not like the old days where you could go to an electronic stores and find the stuff. Highly appreciated.

What hall sensor do I need for bafang g020.250.d

Ji, My cycle is running in full speed in standing condition but while deriving on road the speed comes to zoro within second (my kit is 24v 19.8 ah li battery,24v 250w LY1016z motor and LB27 controller) Battery shows 23.6v in idle condition, while deriving 2.3v dropping. Please give your guidance to find out exact issue. Thank you.

If the display shows me very low battery and when i press the battery button from battery shows me full battery, what can it be?

Tooo good 👍

Happy Easter. I am trying to rescue a abandoned XB-610. When try to connect to batteries three main hub wires got to hot. Hub passed 3 wire test for resistance while turning, any advice where to look forward? Also when testing the sensors, do you use some DC power source? Thanks

How much did you charge for this job

Where is your Shop please?

nice! new sub here!

I thought the white hall wire was a temperature sensor. It is on all the motors I've dealt with

I have e7 error on my display does anyone know and how do I fix it. Thank you.

Excellent work man I think I have the same problem hope I can fix it

Hi there. I managed to mess with the polarity of my ebike which is a 36v 250w ebike the batery is 6 amp. Now the bike doesnt work. What may have damaged? The motor controller or the other major damages? Your suggestion would be highly appreciated. Thanks

I'm in New Jersey where can I buy the sensors

which hall sensor is it? I can't find it online

happy little square wave

How do you tell by a gear hub and other hubs

What's the part number of hall sensor

What happens if the speed sensor is bad or non existent. My new controller has the white wire for the speed sensor but my motor doesn’t have one. The white wire from the controller dead ends at the plug. Will my new controller not work?

if you could guide me to the hall sensor ...maybe a link or so it would be fantastic . no one here in denmark seems to have any , ecept for RScomponents BUT they have millions, so wich should i buy

nice work but background music is annoying + trouble. no music. just work sound

☠️☠️☠️ I've been experiencing extremely dangerous episodes of the motor not stopping as soon as I turn the throttle , related to high humidity conditions ! I think it's because the humidity increases conductivity of the hall sensors in the throttle . can you recommend a good throttle ? I think the manufacturers are going to have to make them water proof. I experienced the same issue with a different throttle , battery and controller. just using the bike after a rain storm is enough to cause the issue. We must have a throttle will a switch to cut power ! ☠️ Also stop using hot glue on the Hall sensors ! It melts were I live ! And make the throttle not Fall apart so easy , and they need to be made with softer grips or made to accept normal grip's.

I have the same problem but mine is a 3000 watt motor hub ( brushless) What kind of sensors should I get and where?

I was confident until the soldering.

Έχω την εντύπωση ότι το άσπρο είναι θερμοκρασία και όχι αισθητήρας ταχύτητας

My hall sensor wire showes 4.1-4.3 is it still defective?

My motor not turning at all , display shows everything working.

Hello Friend I have a 5 KW motor that won't turn at all. It's fairly new and could never use it
