Help needed. Failed Bafang 250w motor dismantled from a ESKUTE Netuno electric bike.

[@OXdElivery]

Eskute Netuno electric bike solution to the motor making a noise but not moving the wheel. Maybe your wheel has randomly gone into reverse. You need to change around the phase wires. Top yellow to bottom green, Top green to bottom blue, Top blue to bottom yellow and if happens again connect back to the matching wires and repeat if keeps happening. Also connect the two white wires to remove the speed restriction. @EskuteElectricBikesUK ​​

[@nunolourenco1532]

It seems you are missing the internal "key": a small metal part that fits in to the axel slot (near the central motor cog?) and fixes the part were the three cogs are attached. Without that key the 3 cogs just spin around and no movement is transferred to the wheel. The part where 3 cogs are MUST be fixed with relation to the axel. The axel itself is fixed to the frame.

[@OXdElivery]

The key is put in correct every time. I know that hat you mean. I done a separate clip of the motor working with out the cover. I still think it's going in reverse. Thanks for your input.

[@nunolourenco1532]

​@@OXdElivery(probably, I've made a better answer for this issue below) If the woodruff key (google it, is not a "magnet sensor"...) is on correctly, then check if the cogs are married to each other (motor >to 3 planetary gears >to hub gear) and are not stripped; if this is ok, check if motor cog is not spinning freely (i.e. not firmly attached to the motor body) (edit: to be sure its moving, try to connect it an run it without the main hub body - but ~carefully~! The 3 planetary gears are reducing the speed & increasing the torque transferred to the outside hub)

[@nunolourenco1532]

Ok, it seems these motors have some sort of freewheel inside the planetary gear assembly (not to engage the electric motor when going backwards...). If I understood correctly, it could be the motor spinning in the wrong direction, as you said before - to fix the direction usually you'll have to unplug any 2 of the 3 wires going from the controller to the motor and rotate them (plug one where the other was, and vice versa), but do your research and double check before trying this. Maybe you can do this also in the controller or display configurations.

[@OXdElivery]

Resolved it some time ago now. The motor randomly went into reverse. I moved around some the wires on the control and now its working fine.

[@trevortrevortsr2]

@@OXdElivery So you had the hall sensor wires wrong

[@BrownPeterAnthony]

Thank you for putting this up and the detail , you explained the problem very well and showed lots of information. Thanks to the comments below I have learned something new,

[@OXdElivery]

No worries

[@Darren-b9k]

FOR WHOEVER HAS THIS ISSUE, 1st thing, The woodruff key is NOT missing as many commentors are claiming. You can see it in place on the shaft at 2:09 into the video. Also The hall sensors are also NOT to blame. The motor IS simply spinning in reverse. . So the 2 options are to plug in the learning wire or change the order of the phase wires .

[@winmarkesconde5651]

i might be too late in the game, but its running on reverse, either change phase/motor wire combination if possible without soldering or prying or if it has a learn wire use that. or change the controller completely if its under warranty. there's no prob with that hub motor.

[@OXdElivery]

Resolved it some time ago now. The motor randomly went into reverse. I moved around some the wires on the control and now its working fine.

[@pauly51]

10:28. No key peg. That slot needs a small chunk of metal. You must of lost or company didn’t add. I believe you’re calling it the magnet sensor. It goes on shaft one way. It locks shaft so motor will spin.

[@OXdElivery]

I know what you mean but in the end it was not that it was the motor randomly went into reverse. I changed around the phase wires untill I corrected the direction and all fine. Thank you

[@Shefflad]

What connects the 3 cogs and the drive shaft from the motor?

[@OXdElivery]

The 3 cogs are not fixed to the the inside case. Should they be fixed to the case? I think this could be the problem as I can't see how it make the wheel move as it is. Both new and old one the same. Thanks

[@PCBoardRepair]

you lost tthe keyway?

[@OXdElivery]

No the motor was in reverse.

Dear i have same u problm in my motor ebike, i think tbis problm in Clutch that is make failed, when use throttel make mailed and make voice in info motor yes

[@ManMan-b5y5c]

Why does your cable come out right side mine is on the other side opp5to the gears

[@OXdElivery]

No idea sorry

[@technocrat7971]

Its running in reverse just swop motor phase around till you find the combination to make it run forward. There is nothing wrong with either motor was no need to dismantle them.

[@OXdElivery]

Thanks that what i think. I will try that. ta

[@youandican2]

There is a key on the shaft that fits into the key way on the planetary gears it doesn't look like that key it there. That would let the motor run but not transfer power to the wheel

[@OXdElivery]

Thanks for the advice. In the end the motor was in reverse for some reason. Just had to change some wires around and the problem sorted

[@ronhollenbeck]

The key is briefly visible at 22:30. It is on the shaft correctly but don't know if it was there when he tried to run it.

[@OXdElivery]

There called the phase wires. I think its was blue yellow red wires been bit time now since i done it so you might want change on the colour of the,. Hope that helps. Ta

[@bensonchukwu813]

Check the motor controller or the motor circuit board. Usually green in colour

Eskute have sent me a new motor but the new motor does the same as the old motor. Eskute have been very good trying solve the problem. Very happy with there help so far. In this video i test both motors and look inside both motors close up in detail. I can not see the problem maybe you can?

[@lakeeconcepcion4260]

its the clutch i guess...

[@RandomClips27.]

Its going backwards 2 things you can do 1 change the 3 phases wires around on the controller 2 there should be a learning wire which you connect and when it runs the right direction just disconnect it hope it helps

[@OXdElivery]

@@RandomClips27. Thanks I did that and the motor working fine now.

[@OnkelK1959]

Hello I had the same problems and symptoms. My wheels were broken. I then ordered new ones complete with the base plate. Unfortunately the freewheel of the base plate was in the wrong position Direction. I then changed the old base plate for the new one. With this one the freewheel is in the other direction. It just wasn't the correct part. Greetings Kai

[@lakeeconcepcion4260]

or the skew? its not attached anymore...there shud be resistance yl spinning the cogs...

[@kurtismckemmie4850]

You need to buy a whole new hub. If that doesn't work you need to bring it back to the dealer where you bought it from. Mine is making a clicking sound with the pedal assist but it's still getting me around. I hope I don't run into this problem.

did you ever get it fixed ??

I just got a new one a day go,, have not been back to it,,, The Hall sensor detects the orientation of the motor and sets the timing,,,,,, It has learned wires...they all maybe vary according to brand

there 3 phase wires i changed around and in the end the motor spun the correct way. You have change them around till you get the correct combo

[@jamie-meanskunk]

Yeah there’s no problem with the motor it’s just running in reverse on the controller there’s two wires to reverse the motor if there’s not two wires to do that, you just swap the phases around

[@Boediprasetya]

@@OXdElivery It looks like the repair you did was by reversing one of the BLDC phase cables. so that previously it rotated in reverse and resulted in the clutch not functioning. The question is whether when the BLDC motor is just installed it functions normally or after reaching a certain number of kilometers the phase changes so that the clutch cannot bite the wheel?

Have you got it working yet? There 3 wires that conect to the control box inside the bike i think its a red yellow and green try changing them around till it works.

For safety the motor will not spin if the sensors do not detect motion. You hear an initial start but it does not increase because there is no feed back
