Pic1. Rotor was scratched.
Pic2. Stator was thicken in one side.
Pic3. Stator was scratched.
Pic4. Stator looked across.
Pic5. Look wire above stator.
I cutted wire. Cleaned inside stator.
Assemble rotor into stator again.
Shaft of motor is free.
Don't hear to rubbing sound between stator and rotor.
Probe each pairs U,V,W together. R(U_V)=R(V_W)=R(W_U) ( about 34 ohm).
Each phase(U,V,W) with GND: O.L ohm.
Fit motor in demo again.
ID RUN:.
the first, DC under volt.
the second, Motor phase fault
the third, it is successful.
ID RUN again:
the first, IDRUN fault.
the second, It is successful.
Running Fault:
Drive was fault when it run with low speed and it had loud sound with high speed.
Best Regards.
