Justin said:FOC controllers have current sensors on the phase leads rather than a shunt on the battery current, and as a result they can run 3-phase hub motors super smooth by controlling the individual phase currents for almost no torque ripple....
We can also get sinusoidal firmware on the infineon controllers for a lot cheaper, but that's not the same as a true FOC control and they don't run in a sensorless mode that way, while the ASI units work great sensored and sensorless even at very high eRPMs once they are tuned appropriately.
