Hello everyone,
I have seen a same problem in a recent thread but it is incomplete, the question was unanswered.
Problem:Motor Rotates for few seconds then stops all i can hear now is jittering sound without any error.Tried tuning as mentioned in AN93637
1.BLDC motor 24V,1.2A has a sinusoidal bemf,with 8 poles,3.1 Ohms(line to line),0.002H(line to line) ,2800 Rated speed,Winding type Star connection
2.It is rotating in open loop.probably, switching to closed loop control is getting failed,so tried increasing smoEst.slideError parameter to higher value however it is not working.
3.The motor with kit BLY172S-24V-4000 has delta type winding ,could that be any problem since the motor am using has y type winding?
It would be great if any one could give an advice.
thanks

Did you change these setting in the program to fit your motor? in you kit manual at section and other sections after that.
5.3.6 Adapting the Example Project to another Motor. Also you as the end user must debug these settings yourself.

What is the part number of the motor you are using and do you have a spec sheet.

Hi Raj,
Some debugging suggestions:
#1 Check if the LED2 is blinking at 1Hz.
Now we can use PSoC Creator debugger to find the source of error
#2 Start the debugging
#3 Put breakpoint on the line if(secFlag) line 107 in main.c
#4 Run the debugging
#5 When the motor stops the debugger will reach the breakpoint
#6 Check the value in the variable 'errState'
Post your observations here.

Thanks for the suggestions Jobin.
Actually LED is not blinking that means no error it is in run state but not rotating .
At First motor is running for few seconds later it stops with continuous beep sound without any error no blinking of led.

I was never able to get a schematic of the winding for this motor. The board only has four connections and you have 6 or 8 I am not sure as you have not stated that information. So I am asking you how many wires does the motor have?
