Other Parts Discussed in Thread: MOTORWARE, DRV8301, TMS570LS3137

Hi,

exists there an example to run sensorles FOC on the DRV8301-HC-EVM with TMS570?

Hi,
Please take a look at this wiki page processors.wiki.ti.com/.../TMS570LS12x_CNCD.

thanks,

my Board actually has a TMS570 LS3137 control card. I looked at wiki at the respective page and cannot find something useful.

In my search I sometimes find a link to a spnc041.zip, which contains motorware. But the software is not for TMS570.

I find it hard to believe there is no sensorless FOC for the DRV8301 with TMS570LS3137. Maybe for another control card ?

Is sensorless FOC rare?

If I have a 600$ Board, it should be possible to use it. The BLDC example seems to be unsatisfactory for our purpose.

Hello,

After you install the motorware did you find the project at the below folder?

C:\ti\Hercules\MotorWare\v1.0.3.03\sw\solutions\instaspin_bldc\boards\drv8301kit_revD\hercules\tms570ls3137\projects\ccs5\project01

Please also read the below post that you might find helpful that talks about some limitation.
