but motor did nit start when i put initial force from hand then it start and run
so what is the mechanisim should i apply to run BLDC


i think i have to increase the frequency with time to start the motor am i right???

I guess you are talking about a sensorless BLDC. Yes, it should be started with a speed ramp.
