Sensorless FOC accuracy

Question asked by Awantha Jayasiri on Jun 8, 2017

We are planning to use STM's FOC for our high-speed motor controller. I would like to know about the accuracy of STM's sensorless estimation of electrical angle compared to the ground truth. Since the Texas Instruments (TI) Instaspin method claims less than 1 electrical degree error, I am wondering such information is available with STM as well.

Thanks
