Part Number: BOOSTXL-DRV8320RS Other Parts Discussed in Thread: LAUNCHXL-F280049C , Hi Everyone!
I've used the LAUNCHXL-F280049C and BOOSTXL-DRV8320RS to control small PMAC motors before without issue. I'm trying to control a small BLDC for the first…
No, you can't eliminate the ripple, just reduce the ripple amplitude if the current and voltage sampling signals have a good resolution and the motor parameters have much exact value. And tuning the gains of speed and current PI controller also improves…
Part Number: BOOSTXL-DRV8320RS Hello,
I am working with DRV8320RS EVM board.
The problem I have at the moment is that the motor runs only upto 3A. I want to test the motor to the max 15A phase current.
Do anyone here know how I can change the current…
Thanks for all the reply!
Sorry it took me awhile, I went ahead and purchased a BOOSTXL-DRV8320RS evaluation board just in case there was an issue with my own board design.
After testing with the eval board, same issue with higher than expected power…
Part Number: BOOSTXL-DRV8320RS Hi
I try to use MotorSDK to control my motor and it is in good condition.
But I want to detect 300RPM~1450RPM torque motor, but when the motor is disturbed, the robustness is very poor. Is there any good way to robustness…
Part Number: LAUNCHXL-F280049C Other Parts Discussed in Thread: C2000WARE , Hello,
I am working through the motor control labs in C2000ware motor control SDK using the launchxl-F280049C with the Booslxl-drv8320RS.
The values I see in the ADC registers are…
Hi Sebastian,

?? ? said: 1. Is this project also a motor identification error?
You need to configure the parameters for identification and use a higher PWM and control frequency if the motor is a low inductance motor, such as 45KHz PWM frequency, 15kHz control frequency…
Hello Kai,
Please find responses below.
The time is about the RL circuit, 1. could I estimate the time by the time constant of the RL circuit?
You could use that method.

Could you help to check the formula is ok or not? and any other I need to notice…
