Other Parts Discussed in Thread: HALCOGEN, DRV8301,
Tool/software: Code Composer Studio
Hey there,
I am driving a three phase BLDC motor using XRM48L952ZWT control card
I have done my complete coding in Code Composer Studio
I have only enabled the GIO and HET drivers from HALCoGen while all of the controlling is being done through the code being burned.
here is my code

after playing the code at no load(i.e. no motor is connected), the waveform appears as shown below:
but when I connect my three phase BLDC motor the output appears as shown below:
and the motors rotates with twice a jerk in a rotation. The major problem of driving at load is that as the motor rotates with jerks, a lot of things are toggling on DRV8301 for example User LED 1 & 3, FAULT LED ,
and the "POW" LED of Control Card RM48L952
Please guide me as soon as possible
