[ARM] Noise in Sine wave BLDC controller

[surendran_raj]

Hi,
I am trying to control a 3-phase BLDC motor. I have already done 6-step commutation, which works fine. Now I am going for sinusoidal control with some guidance could make it good. I had get a good sine wave when it is on no load. when its on load i get some noise but it runs motor can anyone help me to solve this issues.

I created a sine look up table for 360° for 0 to 2·π rad

Sine wave without load

Sine wave with load

Hi,

I guess it's hard to help as long as we don't know:
* schematic
* code
* whether the diagrams show I or V
