DRV8332: Control BLDC motor with DRV8332 and micro-controller

Tuan,

Thanks for posting on the MD forum!

The DRV8332 is an older part, it was created before our more recent parts which incorporate things like 3xPWM control.

For example, a similar part that's newer and has 6x, 3x, or 1x PWM modes is the DRV8320.

There is a convenient EVM board available here that also has simple sensored (motor with hall sensor) or sensorless (without hall sensor) code available:

I would suggest purchasing the above board as well as the MSP430 MCU board that works with it: http://www.ti.com/tool/MSP-EXP430F5529LP

Let me get back to you on some training material.

Hi Adam,

Thank you very much for your advice. I would like to ask you more questions:

-------1/ Could I use an ARM-core micro-controller instead of MSP430? For example, tiva C TM4C123G?

-------2/ Is the driver appropriate for controlling a gimbal BLDC motor (like this one)?

Hi Adam,

After a lot of googling, I found that TI has BOOSTXL-DRV8323RS which has 3 current sensing amplifiers. This driver is compatible with C2000 Picolo controller LAUNCHXL-F28069M which is definitely much better than the MSP430F5529 launchpad. I have another question that, according to your experience, which driver and controller should be used in which case?

Tuan,

Sorry for the delay.

Did you figure out which device you wanted to use?

Hi Adam,

I decided to use BOOSTXL-DRV8323RS as the driver and LAUNCHXL-F28027F as the controller :D :D

I have been also taking a look to the instaspin Labs. I figured out that the lab 4 and 5 shows how to implement the current controller.

Do you have any interesting documents?

Thank you!
