Original question:

INSTASPIN-BLDC: In general terms, is the Insta SPIN BLDC Sensorless FOC algorithm more efficient when directly compare to...

INSTASPIN-BLDC: INSTASPIN-BLDC

Harvey Veselka1
Prodigy 10 points
Part Number: INSTASPIN-BLDC

Is there any data on the accuracy of insta-SPIN or the FAST Estimator as compared to a sensored application. Are there any examples of tuning the FAST Estimator with a shaft encoder for sensor-less operation? 

For example I want to tune the angle accuracy to improve power factor on my sensor-less motors, with a setup off line that has an identical motor that is sensored.

    There is no exact data to show the performance since the speed and angle resolutions are dependent on many factors, such as the current/voltage sensing, motor parameters, and loading.. So improving the current/voltage feedback signal and exact motor parameter are very important.
