可以使用STM芯片的内部闪存来校准电机参数吗？

你好，
我们是一家开发电机控制解决方案的创业公司，我们先进的电机控制器能够同时控制多达8台电机。我们计划在控制器上使用STM的无传感器FOC控制方法，因为我们已经拥有STM芯片的一些经验。我们想了解更多有关STM无传感器估算功能的信息。一些具体问题如下：
1。

STM FOC无传感器估计的准确性。德州仪器（ti）声称其instaspin功能（FAST估算器）的误差范围高达±1电气度。使用STM的无传感器FOC估算电角度时会出现什么误差。

效率与其他换向方法相比。与其他（6步）通信方法相比，您是否有任何关于STM-FOC算法性能的信息？ 3。

什么是芯片系列支持STM的无传感器FOC？4。

我们可以使用STM芯片的内部闪存来校准电机参数吗？5。

你能提供一个我们可以在起点使用并在其上发展的准系统项目的参考吗？6。

我们可以使用Attolic True Studio开发STM无传感器FOC项目吗？非常感谢您提前

Hello,
We are a startup developing motor control solutions and our advanced motor controller is capable of controlling upto 8 motors simultaneously. We are planning on using STM’s sensorless FOC control methodology for our controller since we already have some experience with STM chips. We would like to know more about STM’s sensorless estimation functionality. Some of the specific concerns are as follows:
1.
      
The accuracy of sensorless estimation of STM FOC. The Texas Instruments (TI) claims their instaspin capability (FAST estimator) has error bounds upto ±1 electrical deg. What would be the error in estimation of electrical angle using STM’s sensorless FOC.2.
      
Efficiency compared to other commutation methods. Do you have any information on the performance of STM-FOC algorithm compared to other (6-step) communication methods?   3.
      
What are the chip families support the STM’s sensorless FOC?4.
      
Can we use internal flash memory of STM chips to store the motor parameters once it is calibrated?5.
      
Can you provide reference to a barebone project that we can use at a starting point and develop on top of it?6.
      
Can we use Attolic True Studio for developing STM-sensorless FOC projects?Thank you very much in advance
