是否可以通过SPI总线读取PMSM并将其输入到FOC算法？

嗨，


我有一个PMSM，我计划运行无传感器。

如果我遇到传感器的问题 - 我正在使用的电机也装有一个旋转变压器。我有一个来自模拟设备的解析器解码器，所以我想知道我是否可以通过SPI总线读取它并将其输入到FOC算法？或者我应该使用旋变器解码器IC的正交输出并将这些数字输入运行到STM32中。

如果我有更多时间玩一些采样和保持电路，并使用备用ADC对来自旋转变压器的SIN / COS信号进行采样，并将它们解码到STM32中的位置。但现在这有点儿了。

问候，

Hi,


I have a PMSM which I'm planning to run sensor-less.  

In case I run into problems with the sensor-less the motor I'm using also has a resolver fitted. I have a Resolver Decoder from analog devices so I'm wondering if I can read this over the SPI bus and input it to the FOC algorithim?  Or should i use the quadrature outputs from the resolver deocder IC and run these digital inputs into the STM32.  

If i had more time I'd play around with some sample and hold circuits and use the spare ADC to sample the SIN/COS signals coming from the resolver and decode them into position in the STM32. But that's a little bit off for now.
