Part Number: DRV10974

We are evaluating the maximum speed that DRV10974 can spin our 6 pole pairs motor, and need the information regarding FG maximum out frequency? Can you provide?

Hi PY,

The FG frequency will not be the limiting factor in a system. The FG is limited by the max electrical frequency that the DRV10974 can drive which is about 1500 Hz.

Michael,

What is the relationship between FG and electric frequency. Is it FG = electric frequency or FG = 1/3 electric frequency ?

thanks!

No Problem,

FG frequency = electrical frequency.
