power on the electric bike hub motor was gone

Electric bike hub motor kit was gone, how to solve it?

Received my electric bike kit .Product list:

1.26” 36V 250W front brushless geared hub motor wheel

2.36V 6-MOSFET brushless motor controller working with LCD(display speed,mileage,battery gauge..)

3.standard black twist throttle with battery gauge

4.brake lever with low voltage to brake

5.three button-ON/OFF switches that are used for control front&rear lights,cruise,horn…

Check rim whether in the middle of fork and the direction of hub motor runs.Then I have installed everything on my bicycle according as instruction manual and the electric bike kit worked fine.

I was running e-bike about 25km and then I stopped the electric bike motor . Charged the electric bike battery because I was staying there for some hours. Started on the way home and after some heavy hills (about 3 km)it was completely dead. The electric bike kit system was running like normal up to this, but suddenly all power on the electric bike motor wheel was gone.

Those three led lights on twist throttle for electric bike battery were still lit. I tried to turn e-bike off and on again, but same result.

Today the electric bike kit is still dead.

Do you have any idea? Measured 0,1 Ohm between the electric bike motor(hub motor phase wire: yellow, green, blue).Infinity between hub motor cable and hub motor cover. So it does not look like it is burned. The electric bike motor controller has 41,8 Volt input.

Measure the hub motor hall sensor:

Red, black, yellow, blue, green wires.

1.The voltage between red and black is 4.5V;

2.The voltage between yellow and black is 4.2V or 0V,(When use hand to turn hub motor, the voltage will change from 0~4.5V~0~4.5V)

3.The voltage between blue and black is 0.2V; (When use hand to turn hub motor, the voltage could not change)

4.The voltage between green and black is 0.1V. (When use hand to turn hub motor, the voltage could not change)

From above test data, I doubt there were two hall sensor inside the electric bike motor that were broken.
