M-100 R CST hub motor hall sensor problems.

[peralias]

Hello
It seems that when installing the brake disc, because the standar screws are very long, the Hall sensors of the M-100 R CST have been damaged.

For a design problem if the screws are tightened all the way down the engine brakes and does not rotate at all.

Perhaps when acting on the trottle, when the motor was blocked, there is some kind of damage to the winding or sensors.

I have placed shorter screws but the engine has no strength now and there is no difference between the different levels of assistance.

The throttle does not work.

Has it happened to someone ?

Is it complicated and expensive?

Greetings.

W/ my first Q100, I locked the motor with a screw, but realized it before I tried to run it. On my successive motors, the kit screws are shorter. Are you sure you didn't install one or more of the screws from the original wheel?
At any rate, it does not sound like the problem is w/ the Halls. They "lead" the motor to get it "sync.ed-up" and really don't have anything to do w/power levels.
You may have damaged the windings, but I don't think the "long" screws extend far enough in to make contact.
At this point I would remove the motor core and visibly inspect them. If you want to try this, I can explain some techniques to open the housing cover.
Question, if the throttle does not work, how do you know the motor lacks power?
I suspect the controller. Which one do you have?

Hi Motomech !!
How are you ?

Thanks for your answer.

I placed all the screws, all the way down, I accelerated and did not turn.

Now I put shorter screws.
I went out to ride the bike around the neighborhood.
The engine runs at very low power, there is no difference between different levels of assistance.
 
Engine M-100 R CST
Controller Sine Wade 15 A
Display TK-LC3

I tested the same controller and the same display with a BMP 500W hub motor and it works perfectly.

With the M100R CST in the display it is seen that there is no power demand by the motor hub, it does not exceed 150 w.


I have seen your messages in other forums such as opening the engine.

Once opened, what should I look at?
What to try?
How I should proceed ?

Greetings.
