Trio Cargo e-bike mid drive

[yabert]

all 3 options are viable

Ummm! seem like TSDZ2B and TSDZ8 can not work at 52V (14S batterie).
''Supports up to 54.6V input voltage,this motor cannot works on 58.4V input voltage''
I end to order a new Bafang core stator including hall sensor for 184$ cad.
I hope this will work as our Cargo is our main vehicle here.

So sad that our motor die during chinese new years holidays. Still no motor.
I've recently read that you need two motors to have a reliable ride. One to move the bike and the second for spare parts.
I start to understand why.

When you have the new motor put back together, before installing on the bike, use RTV to seal every seam where water can get in. https://www.amazon.com/Loctite-37467-Black-Performance-Silicone/dp/B000FW7V3C?th=1

Wait two weeks for the new motor, It don't work.
Well, it turn for 10 seconds and then stop. Restart the SW102 display and it turn for 10 seconds.
I remark 2 things:
1-Motor is really hard to turn by hand. I dismantle the motor and at a moment it was not so hard to turn by hand. Put back the screws and it was impossible to turn. So, I try to put 4 washers/spacer between motor and casting to see if this help: No, it's not easier to turn by hand.
2-Stator wires are way bigger on the new motor when compare to the old motor.

Any clue?
I plan to steal the hall sensor pcb from the new motor to at least repair the old motor.

Tried the old motor with the new hall sensor... turn for 10 sec then stop
What???
In fact, at speed setting 1 it turn 10 sec and at speed setting 5 it turn for 5 sec. So it's probably relate motor rpm. Like it turn for 100 rotation then stop.
But why? Is someone had never experienced this?

what signals do you get from teh halls?

Summary:
-This motor was working since 4 year / over 6k Km.
-Last December, we change controller causes of water ingress.
-We add few more hundred Km with the new controller.
-In January, few random Error 8 happen. Over few days, the motor restart up to the moment the motor refuse to spin.
-Few day ago I install the new motor and hall sensor, then the motor spin for 10 sec and stop. I have to cycle On/Off to restart. WTF?

No idea. Are you talking about something who imply oscilloscope?

Oh! This thread lead me to the reason: Bafang BBSHD has started cutting out after a few seconds...
Speed sensor need to be plug and detect a speed. If no, motor stop after few second.

It's really strange to me because 1 year ago we broke the speed sensor and use the bike for few months, without problem, before I take the time to repair it.
That was with the ''old'' original controller. So I bet the software is different in the new controller.
It's really sad that a simple trouble with speed sensor kill the entire motor
