Hi,


As a part of development PMSM drive development, I am planning to buy a EVM. Please suggest a suitable EVM for my below specifications.

1. 10KHz FOC

2. No need of Vdc circuit as we are making our own IGBT circuit.

3. 3-phase PWM generation should be possible for making IGBT to work as Inverter.

4. Qudrature Encoder Pulse reading should be possible.

Thanks & Regards,

    Hi Raghu

    How about this one? https://estore.ti.com/tmdshvmtrinspin.aspx  I think if you have high voltage PMSM motor, a high voltage kits will be more matching in test and varify.

    Also, if you have your own IGBT stage, actually any TI motor driver kits with MCU (C2000 or TMS5x) could be a choice.

    Thanks

    Hi Wilson,

    Thank you for your quick response. But as i said we would like to avoid that 350Vdc power inverter module.

    I have been going through PMSM kits. I found DR8312.

    http://www.ti.com/tool/drv8312-c2-kit#Technical%20Documents

    All I need is a DSP EVM board that generates PWMs for 2 PMSM motors and reads the motor Encoder using QEP.

    So, will DRV8312 serve my purpose?

    Thanks & Regards,

    Raghu K

    Hi Raghu

    Yes. I think so.

    And a better idea is that you can download and install TI controlSUITE first. Then you can find all the hardware and software, and also documents on its install path and folders. (C:\ti\controlSUITE\development_kits). lots of options there.

    You can check more deeply before you buy one.

    Thanks.

    Voltage / Current ratings are required to point you in the correct direction.

    in your last post you also mentioned 2 motor control. Not sure if you want to do that with a single board or not.

    We have an older kit (out of date that we don't do any development on) called TMDS2MTRPFCKIT, it includes two inverters under control of one MCU (F28035) and 2 motors (synchronous sinusoidal with hall sensors).  It is supported through controlSUITE software but only includes software for sensorless FOC.

    We are releasing a new 2MTR inverter board this year @ 24V/10A each inverter, but it will be in the fall.

    For now the "latest" kits are based on DRV8312 (up to 50V/3.5A) and DRV8301 (up to 60V/40A).  These have a mix of controlCARDs that they are "kitted" with, obviously with different software.

    While they both support Encoder feedback, the only ones that include Encoder based softare projects are

    DRV8301-69M-KIT
    InstaSPIN-MOTION solution through MotorWare, with encoder based Speed or Position/Speed both feeding an FOC torque controller.  This is the premium solution we offer.  You can use your own motor if it falls in the power range of the motor, all software for this kit is done with LVSERVOMTR which is the motor included in below

    DRV8301-RM48-KIT
    There are several Hercules Cortex-R4F Safety MCU's from TI that use a different controLCARD with this same kit.  The software is through a MotoroWare style, but not in the MotorWare download.  This is completely "open" software and does NOT support InstaSPIN-MOTION (nor InstaSPIN-FOC).  Does include encoder based Speed+Torque FOC; no Position control example, you must build your own.

     

    Good luck.

    BTW - we also have the 2MTR-DYNO kit

    This includes two of the LVSERVOMTR mentioned above + shaft coupling + frame coupling, to allow you to run one motor as a dyno/load and the other motor under test.

    We initially are using this kit in a workshop with 2x DRV8312-69M-KIT as the inverters under individual control.  In the fall we may move to the new 2MTR-69M-KIT which will allow a single PC/MCU to control both inverters.

    We also are manufacturing a low voltage induction motor that will attach to one side of the 2MTR-DYNO so you can test ACI motors under load as well.  A good platform for testing control algorithms that will be well supported by TI.

    Hi Chris,


    Thank you for your response. I want to have two motor control with only one board. currently, I am usingTMS320LF2407A EVM board for my programming. This is a very old version of this motor drivers series.

    I found DRV8312 as a suitable EVM. As of my understanding the only difference between DRV8312 and DRV8301-69M-KIT suggested by you is MotorWare software. How much this software will be useful for me?

    To control 2 motors i need 12 PWM lines generated from DSP. These signal line in the suggested kits are given to inverters of 60Vdc. But is it possible to tap these signals out, as we are building our own Inverter of 300Vdc.


    I am trying to get technical reference documents for these both EVM boards to understand their capabilities. But I couldn't get the in TI's site. It seems i will have to download controlsuite for that. you see it is difficult for me to install this controlsuite only to get technical reference documents of EVMs, because of our organization rules.

    Is it possible for you to give the suitable site links to download the required technical reference documents that help me judge the capability of these EVMs.

    Raghu,

    If you are building your own inverters board you should probably just put in our controlCARD connector or just solder a chip down.  I would recommend the 100-pin TMS320F28069MPZT as a good superset device.  This will let you use InstaSPIN-MOTION and InstaSPIN-FOC through MotorWare or any of the non-InstaSPIN examples through controlSUITE. 

    All of the hardware documents for controlCARDs, inverters, kits, etc. are in controlSUITE  You will have to download at least the .zip file from the controlSUITE folder
    controlSUITE zip package - v3.2.4

    DRV8312 & DRV8301 = 60V Bus
    BOOSTXL-DRV8301 = 24V Bus
    HVMTRKIT = 350V Bus  (sold as TMDSHVMTRINSPIN and TMDSHVMTRPFCKIT)

    Hi Chris,


    what are InstaSPIN-MOTION and InstaSPIC-FOC? Are they firmware provided by TI?

    We want to develop our own firmware for PMSM motor control with SVPWM algorithm and current feed-back loops.

    As per my search in the TI' sit for my requirement the F28035 controlCARD in http://www.ti.com/tool/tmdscncd28035 and it's dock in http://www.ti.com/tool/tmdsdock28035 shall be sufficient.

    What do you think.?

    Thanks & Regards,

    Raghu,

    You can read about www.ti.com/InstaSPIN-FOC and www.ti.com/InstaSPIN-MOTION from our website. Yes, they are three phase motor control solutions built with software (MotorWare) and firmware (on-chip ROM). 

    When you say you want to develope your own firmware...how far do you want to go?  Software for full FOC controrl systems are already available, so I'm not sure why you would want to re-invent the wheel when it comes to Park, Clark, PI, SVM, etc.  If you want to re-use these common functions and have a framework you can use controlSUITE for MACRO style coding (connect outputs of one software macro with inputs of another) or MotorWare for object oriented descriptive API.

    Sure, a docking station may make sense to wire into your inverter. Be careful with noise on getting the sampling from the inverter to your MCU.

    Not sure why you chose the F28035, but I'd suggest the F28069 instead. This has more MIPS and memory and we use it as our R&D device for everythign we do.  It is also drop in compatible with the F28069M which allows you to run the InstaSPIN solutions discussed above.

     

    Good luck.
