TIDA-010025: Development of BLAC/BLDC drive

Part Number: TIDA-010025
Other Parts Discussed in Thread: DESIGNDRIVE, , TIDA-00366, TIDA-01349, TMDXIDDK379D, C2000WARE, TIDM-SERVODRIVE

With the designs given in the link: http://www.ti.com/tool/TIDA-010025#supportandcommunity,

Is it possible to develop BLAC/BLDC drive (Rating: 2kW,200/400V @6/10A). Can I use C2000 controllers to implement FOC for controlling Position, Velocity and Current of BLAC/BLDC motors. Please help and Thankyou

  • Hello Teja,

    thank you for your interest in the TI design and the C2000 Microcontrollers. The C2000 MCUs are very well suited for development of BLAC/BLDC drives with cascaded control of position, speed and torque (FOC). 

    Please visit http://www.ti.com/microcontrollers/c2000-real-time-control-mcus/overview.html to get to a first overview on the C2000 realtime control capabilities for digital motor control.

    For motor drive evaluation, please visit http://www.ti.com/tool/TMDXIDDK379D, which provides the C2000 DesignDRIVE Development Kit for Industrial Motor Control for position, velocity and torque including software support. 

    The DesignDRIVE Development Kit (IDDK) hardware offers an integrated servo drive design with full power stage to drive a high voltage three-phase motor and eases the evaluation of a diverse range of position feedback, current sensing and control topologies. The sophisticated sensing peripherals on the C2000™ MCU, including eight delta-sigma sinc filters, four high-performance 16-bit ADCs and eight windowed comparators, enable the DesignDRIVE Kit to support shunt, fluxgate / Hall, and delta-sigma current sensing simultaneously. For position feedback, the kit leverages Position Manager solutions integrated integrated on the C2000 MCU supporting EnDat, BiSS, T-format, A-format, incremental encoders as well as SINCOS and resolver analog sensors. In addition, customers can also explore configuration options that allow the MCU to be placed on either side of the high-voltage isolation barrier. The IDDK is supplied by a single set of 110V/220V AC mains, delivers up to 8 Amps and is rated to drive motors up to one horsepower.

    We also have a dedicated software suite for digital motor control with the C2000 MCU, which you can find here: http://www.ti.com/tool/C2000WARE-MOTORCONTROL-SDK. This may be used also to develop with your own hardware.

  • Thanks a lot for the detailed explanation. Can we download the BOM & schematics of the above mentioned kit for developing our own hardware with the TI devices. As I can see, this kit can be used with 1Hp motors. With proper electrical design can we improve the rating of the drive upto 2kW?

    Also, I need information regarding the design files and the BOM required for developing our own hardware. Please help and thankyou.

  • Hello Teja,

    you can download the BOM file, schematics and even Altium CAD files of most reference designs like TIDA-010025. For TIDA-010025 you can find this

    under www.ti.com/tool/tida-010025 

    http://www.ti.com/solution/servo-drive-power-stage-module 

    please go to "Design Files" to download the BOM, Layer Plots, Schematics and even Gerber files. An important note you will find in the user's guide too is: 

    TI intends this EVM to be operated in a lab environment only and does not consider it to be a finished product for general consumer use. Hence

    please consider this when building your board. To increase the power level (e.g. at the same DC-link voltage) you'd need to follow common design practices,

    such as validating if the IPM (a non TI product) is capable of driving 2kW at the temperature range you specify and the current sense shunts are specified to

    handle the current your specify for nominal / maximum current and temperature range. 

    To learn more about design practices of 3-power stages, I'd recommend reading the our various reference designs for 3-phase power stages, which you can find under the link http://www.ti.com/solution/servo-drive-power-stage-module I mentioned above already. Examples include TIDA-010025, TIDA-00366, TIDA-01349. Especially www.ti.com/tool/tida-01349

  • Hello Teja,

     

    for whatever reason, the formatting screwed up and deleted some text sections in my above answer. Here's what I wanted to write:

     

    You can download the BOM file, schematics and even Altium CAD files of most reference designs like TIDA-010025. For TIDA-010025 you can find this
    under www.ti.com/tool/tida-010025 then section Design Files. You can find even more reference designs for e.g. servo drive power stages under http://www.ti.com/solution/servo-drive-power-stage-module In the block diagram select the building block 3-phase power stage, and you’ll see relevant reference designs on the right. Please note that you can select between three different subsystems in the block diagram, IGBT, IPM and DC-fed 3-phase power stage.   

     

    For the Industrial Servo Drive and AC Inverter Drive Reference Design please here: http://www.ti.com/tool/TIDM-SERVODRIVE#technicaldocuments Then navigate to Design Files to download BOM, layer plots, schematics and Gerber files, if needed.

  • Thanks for the help. Can I get bom and Gerber for TMDXIDDK379D evm kit? If yes plz give us the link.

    What is Ipm? Is it intelligent power module(igbt)?

    What I understood is with this TMDXIDDK379D kit along with c2000 controller I can use foc and move a brushless motor. Is it possible to develop our own user interface using c#?

    Actually For my application I've to give commands to the controller using user interface in pc. Is that possible?

    Plz help and thanku

  • Teja,

    for the BOM and Gerber file for TMDXIDDK379D, can you please follow link I provided above: For the Industrial Servo Drive and AC Inverter Drive Reference Design please here: http://www.ti.com/tool/TIDM-SERVODRIVE#technicaldocuments Then navigate to Design Files to download BOM, layer plots, schematics and Gerber files, if needed. 

    An IPM is an intelligent power module (e.g. includes gate driver and IGBT), please refer to www.ti.com/tool/tida-01349 where we use and IPM. The design guide give more details.

    Regarding software development on C2000: Please refer to http://www.ti.com/tool/DESIGNDRIVE  where you can find the corresponding information on developing software:  

    DesignDRIVE Software is supported by the C2000 controlSUITE™ package (original projects) or C2000Ware MotorControl SDK (latest projects) and includes the Fast Current Loop, examples for speed and position loops, drivers for Position Manager solutions and many current sensors to help developers jumpstart their evaluation and development. In addition, the kits come with TI’s Code Composer Studio™ integrated development environment (IDE), providing code generation and debugging capabilities.

    I'd also recommend watch the DesignDRIVE training series to learn more. 

    Thank you.

    Martin Staebler

  • Thanks a lot for the information. Is there any particular software to open and edit the Gerber files as my application needs some modifications.

    Thanks and Regards...

  • Hello,

    I assume you refer to the http://www.ti.com/tool/TIDM-SERVODRIVE#technicaldocuments?  In that case you may check for a free Gerber file viewer or editor of your choice. TI does not offers such tools.

    If you however refer to the TIDA-010025 reference design, you can download the entire Altium CAD file from the corresponding TI design folder. In that case you would be able to modify that CAD project by using Altium Designer.

    We do not have the CAD files for the TIDM-SERVODRIVE though. In that specific case, you may search the internet or contact a PCB tools vendor of your choice to get a Gerber file editor.
