I like the H bridge discussion, but do not see how that will help
on a brushless motor.
I read the problem as being with the PWM part of the picture.
How about:
changing the PWM base frequency
filtering the PWM'd output. (May not work well with brushless
motor, but would be ok for regular motors.)
I play with HP HCTL-1000's for motor control. They may be worth a
look.
Good Luck!
