TMS320F28069: Switched Reluctance motor control - position sensing

mohana sundari43

Part Number: TMS320F28069

Dear Sir,

https://e2e.ti.com:443/I could measure the variation of inductance of SRM using HR capture module.

I could measure the variation of inductance of SRM using HR capture module..Thanks for all your support. I have to start my hardware design as well as start my application code.

I have some doubts how to do the Q value conversion. to use it for rotor position sensing in my application software. Cna you send me the sample code.

Also I wanted to the latest TMS microcontroller suitable for motor control application and whose EOL is far away as well as 3 caputure inputs required.

With lot of PWMS and adcs. And also pl send the reference designs.

thanking you

Warm Regards,

S..M.Sundari

Sorry, we don't have such reference design or code for SRM till now, you have to handle this by yourself. Maybe, this is our future target to have one. Thanks.
And all C2000 controllers can support SRM control from the peripherals side, you might find the active C2000 controllers as the following link.

Dear Sir,I have some doubts how to do the Q value conversion. to use it for rotor position sensing in my application software. Can you tell me the logic? to be implemented as part of application code.

You may have a look at the following links that will help you to understand what's the IQ format and scaling, and how to use the IQ format in motor control project.
