INSTASPIN-BLDC: Where is some documentation?

Part Number: INSTASPIN-BLDC
Other Parts Discussed in Thread: CONTROLSUITE

Hey there!

I want to use the InstaSPIN_BLDC function to spin my BLDC motor.

Now I am looking for some documentation how to use it.
I just found the header file and the example projects of several development kits.

But I would like to get some general information, like:
Which hardware is necessary in general?
Which inputs are necessary in general?
What should the input look like in general?
...?
In fact, I would like to get a manual. (I found just one for InstaSPIN_FOC and ~MOTION.)

Where can I get this?

Thanks in advance!

Sarah

    Most C2000 motor EVM kits support instaSPIN-BLDC, for example, DRV8312-kit, DRV8301-HC-Kit, HVMtr-Kit. Three phases voltage of motor and dc-bus voltage sampling circuit must have on the h/w board.

    You might find an application notes (InstaSPIN-BLDC Sensorless Control.pdf) in below folder if you installed controlSUITE, that should have all the information you wanted.

    What is the HVMtr-Kit?

    I found the documentation. But it doesn't help me really.

    I am using the InstaSPIN_BLDC-function on my own hardware. But it doesn't work. And I can't find the difference between my code and the example code.

    This is why I would like to have a manual, so I can check the conditions of usage.

    So is there some general manual for InstaSPIN_BLDC?

    You might find the HVMtr-Kit (High Voltage Motor Control and PFC Developer's Kit) as below links.
    www.ti.com/.../tmdshvmtrinspin
    www.ti.com/.../TMDSHVMTRPFCKIT

    What board and MCU controller did you use? You can also find the schematic of these three kits in controlSUITE folders, you could refer to the schematic to design your h/w board. As replied to you above, the 4 voltages sampling must have for instaSPIN-BLDC.

    This is the only one document for instaSPIN-BLDC, and you could find a guide about some modules which are used in the project in controlSUITE. These documents should be fine to migrate the project to your h/w board. You just need to change the BLDC_Int-DevInit_F2803x.c for your h/w board, and tune InstaSPIN_BLDC1.Int_Threshold according to the motor.

    Okay thanks.

    One more question: The voltage of DC bus isn't needed by the InstaSPIN_BLDC-function itself, correct?
    I just found it here: if (RunBLDC_Int==1 && Gui.VdcBus>Gui.Min_VDC && Gui.VdcBus<Gui.Max_VDC)

    Right. It mustn't have for instaSPIN-BLDC module, is only used for protection in the project.
