Thanks to you good folkes, I have successfully repaired my front hub motor. I had a burnt hall sensor and three wires that needed fixing. I watched this vid many times, used all your info, got parts from your advice and absolutely fixed it. The most difficult thing was soldering in the sensor but yet again I used your advice and laid the leads over and got her from the back... Worked like a charm. I'm mobile again.. You cats are great!!!!

Great video Justin! Thanks :D

1:33 Most Hall sensor testing circuits that I've seen would only light the LED when the hall sensor pulls the signal wire low, therefore I would expect the corresponding LED to stay off continually rather than "staying lit up the whole time" if the signal wire was broken. 11:37 If you are using a separate magnet to check the Hall sensors on a direct drive motor with the stator removed from the hub, all three Hall sensors should be in the same state (all LEDs Off) before the magnet is introduced. The magnet may need to be reversed to confirm that the sensors also switch both high and low. Yet another very useful video that is eZee to follow and understand.

Hey there, you are correct about the detail at 1:33. I realized that as I rewatched the video too, but most people will have a multimeter instead of an LED hall testor and their assumption would be that LED on = 5V so I think it's OK that this can slide... ;-) Thanks for the feedback.

Grin Technologies I made this assumption! What do you think would be the reason for all three hall lines to give 5-4v even after I have completed an entire rotation backwards? Similar to the issue described in your video, one of my power lines shorted to the red hall line. When I press the throttle the wheel will jerk forward very slightly and only for a split second. As far as I can tell, my battery, 48v controller, and computer are all in good shape. Any insight would be appreciated, thank you!

Im trying to diagnose my nanobot d4+ 2.0 scooter. This problem does not happen in the cold morning on my first ride but happens in middle of day when it is warmer. Im in NM. What happens is both motors cut out when I'm in dual mode and when i go full throttle, and also sometimes when i try to just accelerate quickly. when it cuts out i does not come back alive by simply backing off a little on the throttle but i have to totally go back to 0 or no throttle and then the motors start if i re-engage the throttle more gently incrementing the speed. It does not happen in single mode when in just rear hub drive. When in single mode i can press the throttle fully and as quickly as I like. If I think of the thumb throttle as a clock that goes clockwise from 12 to 6. it is at the 5 when the motors cut out. It also happens if i got from 12 to 3 very very quickly. I'm pretty techy and i can replace of fix most anything but I like to diagnose first. I did have an extra thumb throttle speed controller so i did decide to replace that (because a year ago i brew out its usb power port when making a dual charger for a camera i have) but changing that speed controller had no change in the symptoms. Do you think there is a short somewhere in the system on full power or is it a hall sensor. Is it overheating and the bms cutting out? There are two controllers in the scooter with a communication wire between them, could one of the controllers be off. Both motors shut off when this happens. What tests should i run to see where the problem is? I have opened up the scooter before because I silicone sealed everything to protect from water. but actually moved to NM where there is little rain and I do not ride it in mud or water anyway. Any help appreciated.

Just avoid more impacts! A small chip won't have any effect on performance, but it does remove the protective nickel coating over the rare earth making the magnet more vulnerable to corrosion issues if it gets wet.

Unfortunately we don't really know anything about ninebot controllers and products. But what I would do is look at the actual hall sequence on your one working motor and see that the motor you replaced the halls in matches that for the sequencing. Flipping a hall upside down should only be done if you are sure that is required for either the 60 degree or 120 degree hall timing of the motors.

Well, it's definitely not hall sensor issues which is the subject of this video. It's also for sure not related to greasing. Hub motors do not require maintenance greasing and frictional losses here are totally imperceptible to motor performance. Hopefully your friend can get support from the person or company that sold him the ebike. (That is assuming that there is truly a quantified issue and not just a subjective opinion that it feels weaker, which may or may not be actually true.)

Normally you would have the motor cable plugged into a controller that was hooked up to a live battery, and that would energize the halls for doing the measurements. But in this video we had a stand-alone motor hall tester which has it's own internal 9V battery for that.

Yes but it is quite an advanced skill set, so I'd build a few DIY ebikes from kits first in order to more fully understand all the components. And then if you still feel like retrofitting the controller in your Shimano ebike you'll at least be comfortable with the component landscape. Hooking up the 3 motor power leads to a sensorless BLDC motor controller and making the motor spin under throttle control is fairly straightforward, but there is very little chance that you'll be able to interface with the Shimano battery, torque sensor, and other electronics. Everything else about the setup about will likely need to be aftermarket as well.

I would check for damage on the wiring where the cable exits the axle first, and if nothing seems suspect there then open it up. Some motors have disk screw holes that go right through the shell and into the motor body, ie not blind holes, and we've seen cases where screws that were too long actually poked through and damaged the inside of the hub. We've also seen cases of blind screw holes where people used a screw that was too long and it punched right through the blind end of the hole to dislodge a piece of the diecast casing that then was loose inside the motor and caused damage.

It's not very easy to tell by just looking at a motor stator where you want to place the halls unfortunately. It's easy to space them all 120 degrees apart based on the magnet pitch but the absolute location of the first hallwould be tricky without knowing the winding deails. I would take a guess initially, then use a motor controller that shows the hall offset in degrees and then shift them to have your desired hall offset.

I have a rad power bike Rad Runner2, I'm not the world's greatest electrician,I'm waiting on my brother-in-law at the moment to help me diagnose My Hub issue whether it's the hall sensor or a couple burnt windings on the motor.but after replacing the speed controller twice, the wiring harness,and the Pas sensor.and both times I reassemble the bike and tried to see if it would work two of the plugs on the speed controller coming from The Hub were semi burnt scorched.waiting on my brother-in-law to come up from Fort Worth to Wichita Falls to watch this video right now so he can help me diagnose this Hub issue I have.but from all the videos I've seen and I've only watched halfway through this one I'm thinking it's more of maybe a burnt winding then it would be a hall sensor was curious as to what you might think would be the cause of burning out the plug from the Hub motor to the speed controller and leave it squirts like it has but.I will definitely let you know what my brother is able to deduce after watching this video

Hi there. I have a question. The hall sensor must touch the magnets or it doesn't matter where you put the sensor?

The location matters quite crititically since that determines the hall pattern and hall timing, so you want to replace them in the same spot, uness you REALLY know what you are doing in which case you could put them in any other location that results in the same effective hall transition point. They should be close to the magnets to reduce effect of stray fields, but obviously not touching.

How did you remove The Black case On to reveal the inside of the motor?

The side plate screws are removed with a screw driver or impact driver if they are quite tight, and then the hub just opens up.

If you can find a spec sheet for the old halls, try to find one that has the same or close specs. There are ratiometric , linear sensors and digital sensors. The best thing to do would be to replace all of them with matching part #s. and use the same type of sensors that is original so everything continues to work right with the controller. Be sure you get the pin connections right also with the replacements.
