LAUNCHXL-F2800137: sensorless FOC Constant torque control.

Part Number: LAUNCHXL-F2800137

Hi Sir

I use the F2800137 launchpad with DRV8323RH EVM developed verification the Constant torque control,

Also refer to the following discussion:

https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1272198/tms320f280025c-universal-laboratory-torque-control-out-of-control/4828139?tisearch=e2e-sitesearch&keymatch=Constant%2520torque%2520control#4828139

My question is whether there are better suggestions for sensorless FOC applications that require low speed and constant torque?

thanks.

    The Universal Motor Control Lab is the only relevant software solution we currently have for this kind of application. For low speed and higher torque applications we often see higher pole-pair count motors and some kind of angle sensor (commonly HALL based if lower cost) get used.

    Best,
