Instaspin-FOC DRV8301-69-KIT Labs 6-8

Hi Chris,

My customer is looking for examples code on Lab 8 of InstaSPIN-FOC as well. Are there any update about its availability at this point of time? 

Thanks so much,

Regards,

unfortunately the June release will not have any udpates for lab 6 or 8.

the June update will feature an update to the drivers for PWM register update, easier PWM to ADC SOC decimation (through a user.h TICK), and various small fixes.

A larger update for the missing labs (which requires more documenation work) will follow.

Hi Chris,

Do we have any specific schedule on when we can release lab 8? I would help me a lot to work with my customer.

It will probably be end of July. We have another major release planned at that time for additional support.

Thanks, Chris.

BTW, lab 8 is just on using PowerWarp.

And the flag to control PowerWarp is already in the update global variables function in most of the labs.

  // enable or disable power warp
  CTRL_setFlag_enableEpl(handle,gMotorVars.Flag_enableEpl);

C:\ti\motorware\motorware_1_01_00_07\sw\solutions\instaspin_foc\src\proj_lab09.c

Just run lab09 (or any lab where you can update this variable in the global variables, or add yourself), add gMotorVars.Flag_enableEpl to the Expressions menu, and you can toggle it on and off.

That's all there is to PowerWarp.

Monitor Id and you will notice when PowerWarp is enabled and load is low the Id magnetizing current wil diminish, your entire Is will lower, savings enormous amounts of energy.  When loaded the motor will be slower to respond - and may even stall if the even t is fast enough / high enough torque - but FAST will recover and InstaSPIN-FOC will regain control (assuming of course all the parameter were ID'd corrrectly, controllers tuned appropriately,etc.).

One of my favorite things is to watch a power supply with PowerWarp disabled and then enabled.  Just amazing how much current is being wasted in induction motors!!!  And controlling with with PowerWarp now makes induction motors much more attractive to a variety of variable speed applications.  The overall system efficiency, combined with the cost and complete reliability makes for a nice overall package vs. PM/BLDC in certain applications.

and BTW, it is mainly the documentation that is missing for labs 7, 8, and 9.  The code is there for 7 and 9, and as I posted 8 is a simple flag. We just need to write documentation to explain some of the theory.
