I received the IHM03 Motor Kit, which spins the supplied motor "out of the box", but I can't connect through the UART port and run the Motor Profiler. The Profiler attempts to connect at different baud rates then fails with an error that it can not c...

The code in mc_tasks.c in routine void TSK_MediumFrequencyTaskM1(void) callsbool IsSpeedReliable = STO_PLL_CalcAvrgMecSpeedUnit (&STO_PLL_M1, &wAux);This function computes the average mechanical velocity, among other things. The above function is not...

I need to convert a project from SDK 5.4.4 motor code to 5.Y.4.My motor project started out on a Nucleo board with a 64-pin STM32G431 with an 8V driver board but my product became a 48-pin STM32G431 with a 5V driver. Because of this my *.stmx and *.i...

I am operating a low inertia BLDC Motor with the STM32 FOC Motor control library. I have modified the code to add an outermost loop that provides phase lock control to an external reference.The one limitation I have is that I think the inner speed l...

I use STM32CubeIDE (1.5.0) as a toolchain without a current CubeMx file. What is the means of upgrading motor drivers from 5.4.4 to 5.Y.4?I have done the basic install of 5.Y.4 under folder C:\Program Files (x86)\STMicroelectronics but in my CubeIDE ...

Hi,This was some time ago so I forget the solution I found. However, I did write a blog on the use of the DMA in a phase detector. This was the problem I was solving at the time. My blog link is here:https://tremaineconsultinggroup.com/phase-detector...

I think the use of Hall devices for speed control is your problem. At 50rpm with 4 pole-pair your electircal frequency is only about 3.3Hz (your Hall rate). For this rate I think your closed loop BW would need to be less than 0.3Hz to be stable but a...

How many pole-pairs does the motor have? What PWM frequency are you using? What closed loop bandwidth are you trying to achieve? Let me know and I'll give some thought to it,Brian

Just saw this answer today, will definitley check this out and report back,Thanks,Brian

Update:I think the rotor speed calculation is done in STO_PLL_CalcElAngle with the moving average done in STO_PLL_CalcAvrgElSpeedDpp but these procedures are NOT available a source code. A consultant who works with ST provided 'private' functions STO...
