DRV8323: Sinusoidal commutation example

Gunter Schmer

Part Number: DRV8323
Other Parts Discussed in Thread: MSP430F5529, DRV832X,

Hi,

a customer is using the DRV8323BOOST boosterpack with the MSP430F5529 LP are able to run the OOB Trapezoidal Sensored and Sensorless BLDC from the DRV832x_EVM_BLDC_FW_1.0.0 package.

The DRV8323 mentions sinusoidal commutation as well.

Are there any examples for sinusoidal commutation available, even if it is on a different MCU like C2000?

I noticed there is an Instaspin FOC example with C2000, but here we would need just a Hall sensored BLDC control, but with sinusoidal commutation.

Thanks,

Hi Gunter,

Sorry, I clicked too soon.

As you noted, the C2000 example is Instaspin FOC.

Hi Rick,

is there an example with just sinusoidal commutation, but not FOC. We would need just sinusoidal BLDC control (Hall sensored).

Thanks!
