stator and controller bafang mid drive

short answer is you can't test these things with just a multitester.
If your controller is still good, it will tell you what's wrong with the motor by showing an error code.
If you did not see any error code before the motor stops working then it's likely one of the 3 items: LCD, waterproof cable or controller.
The motor is usually very solid, it will survive most adverse conditions.
Your Hall sensors may be cooked if the motor overheats but the controller would have reported an error code for that.

Thanks!
I didn't see ANY error code, in any case or situation.
But the engine doesn't work correctly.
I lifted the rear wheel and started the engine with the accelerator on my finger, the changes of PAS happen correctly BUT with each PAS (1,2,3,4 -....) the engine suddenly marks a brief and noisy shutdown, as if the gears or something else stopped working. It is for this reason that I imagined that the stator kit could be in question, a copper wire possibly would have broken which can cause short engine interruptions.It is a bbs01b 250w that I unleashed at 35km / h and I believe that this error causes me the current concern.I don't know exactly what it is, my warranty is lost because 35.I intend to dismantle the engine piece by piece in order to find the broken one.From what you tell me, I think it's the gears, namely pinion, big one gear or nylon gear.
But why the controller doesn't show anything?
How to be sure the controller works well or not?

if your visual inspection has not shown up any broken gear, then it's possible that the one way clutch inside the nylon gear next to the motor may be slipping.
Did the problem happen only when you go up a steep hill?

Hi woosh!
I have my engine in pieces now, it is impossible for me to unscrew the 3 fasteners of the nylon gear cover! I am furious, because all the other screws were very obedient! What I notice is a smell (maybe normal?) Which emerges from the stator kit and OPTIONALLY the copper wire has slightly burned .... I tried my ohmmeter which signals a sound for the stator kit and the controller, which leads me to think that these 2 elements are functional ... BUT as I can't open the nylon gear cage, nor for that matter the axle cages to check the bearings, I have decided not to complicate my existence and I will order a new BBS01B without accessories, which lowers its price! And, if I feel like it, I will rebuild the "defective" bafang and install it when I have to do maintenance on the new ...

These screws are often extremely tight to undo and need a vice and an impact driver to loosen them. From memory, they are Phillips 3 size.
I think that is a percussion/hammer drill. Related but not quite the same. The impact driver works by simultaneously giving a kick forward to loosen the screw (especially if its rusted in) with an anticlockwise kick to unscrew a small amount. Also, because it's kicking forward the bit bites into the screw head; this reduces the risk of stripping the screw head in the unscrew action..
i like to use one of these, rather than a cordless impact driver. Sometimes the large handle will give enough purchase to loosen those screws without any striking with hammer. It's most important touse the right size bit, otherwise you will damage the cheap Chinese screw head, which will make the job even harder.

Its name is (manual) impact driver.
It works as I said above. I didn't mention, you engage the bit in the head of the screw, then give a wollop with a big hammer on the back end of the impact driver.
The hammer blow directly applies to give the forward kick.
It has a very simple mechanism inside to give the small twist to the bit from the same blow.
Even though simple it needs to be good quality because of the impulse blows; needs good quality bits too.
