Hi,
Some advice needed please.
[mandatory:] We want to work with: f280049C controller and a DRV8320 or DRV8353 and a 15 pole (pair) BLDC motor which we want to control at low speeds and with torque. Powered by 24V.
According to your website, with low speeds and torque, it is best to use a sensored setup. For now we have HALL sensors in our motor.
Edit: we also have an incremental / quadrature encoder available.
We have tried the DRV8353RS-EVM board, no sensors connected. With the example program we have got the motor spinning, but not really great. In comparison with other TI motor projects (eg. drv8320), this setup uses the F2802x controller. Which I think is a real pain to port to f280049C, because it uses complete different libraries and project setup, which are not available for the f280049C. And sample code is hard to find.
Now we are working with the BoostXL DRV8320RS with launchpad f280049C. I tried the labs and some work, but some won't. At least I got the servo_drive_with_can_f28004x project working. The motor spins ok, mostly at higher speeds (which is perfect for sensorless setups). But it looks like it is not really possible to attach HALL sensors to this board. And no example software available.
I found this thread, but this is a different hardware setup (and some software refered in these docs are not to be found).
My gut feeling says that the BoostXL DRV8320RS with launchpad f280049C has the highest chance of succesfully connecting HALL sensors and running the motor with torque at low speeds (= what we want!).
Please advice/guide me in which sample software to use and to look at, to embed HALL sensors to 'a' project for this type of controller. Please point out some usefull documentation if available.
Used motor KM062 (BLDC motor):
Is this motor usable with the f280049C controller and a DRV8320 or DRV8353?
