RE: DRV8307: Hall sensor spacing

Hi Rick,

Thanks for the reply. I've tested two types of motors on the DRV8307EVAL boards; one has 120 deg spaced halls and the other has 60 deg spaced halls. The 120 deg motor doesn't work at all, but the 60 deg motor works beautifully. Both motors use the same hall sensor IC, at least according to the mfg, both are 24V but they don't have the same number of poles; one is a 4-pole, 60deg spacing, and the other is a 14-pole, 120deg spacing and it's the one that doesn't work correctly with the DRV8307. Thoughts?

Thanks,

Phil
