FOC Motor Control with Encoder

[ReTh_4460746]

I work with the Motor Eval Kit CY8CKIT-037 and the example project "Sensorless FOC Motor Control".

I would like to replace the observer with my encoder. (I know that the code of the observer is not open source.) The observer estimates the following variables. It would be very helpful if someone could tell me what the variables stand for, what units they have and in what "format" they are available. (What I mean by "format", for example: the angle from 0 to 360 degrees as a number from 0 to 1024).

i32Q8_Ealpha

i32Q8_Ebeta

i32Q8_EstimWmHz

i32Q22_ElecAngle

i32Q22_DeltaThetaTs

Many thanks

Hi Reto,

Could you kindly point us to the example code version you are using ? A link to the landing page will be sufficient.

Hi Vasanth,

I am using the example project "Sensorless FOC Motor Control" from the following file: https://www.cypress.com/file/141166/download

Otherwise you can find the file also over: https://www.cypress.com/documentation/development-kitsboards/cy8ckit-037-psoc-4-motor-control-evalua...

under "Related Files" the file named "Download CY8CKIT-037 PSoC 4 Motor Control Evaluation Kit Code Examples".

Best Regards,

Reto
