The Motor is new (2 Runs in TC)
The ESC is ok (with Nosram Pure2 6,5T no problems)

what is the solution of the problem ???

i have seen that before but on a different brand of motor, after replacing the sensor board in the motor it sorted the problem

okay .... i have tested it and it is the same problem with an other sensor.
the suspect sensor works fine in another motor :( other sensor cable I have also tested.............
