What's Your Biggest Challenge In Implementing Motor Control In Projects?

rscasny

We have a lot of motor control content and projects around the community. To make sure we are putting up the right kind of motor control content or offering the right kind of motor control projects, I want to ask everyone about their challenges implementing motor control, drives, etc. Please add your comments below. Thanks.

  • BLDC, PMSM, trapezoidal BEMF

    Motor control has increased in complexity since I was in school.

    I have trouble justifying adding a lot of complexity to most motor projects.

  • Yes, as says, driving BLDC motors is a whole different ball game. Simple stepper motor/ brushed DC is easy, but BLDC is a lot more complex & is a step above the level of most hobbyists projects: from basic trapezoidal, to sensorless and field oriented control, there is a pretty steep learning curve to learn the theoretical concepts. Implementation is another challenge in itself because the hardware needs to be exactly to spec when dealing with FOC since the whole system needs to be tuned. Sensorless trapezoidal is more flexible in that sense because it's more plug & play friendly.

     

    Vendors are certainly trying to make it easy by doing most of the hard work for you, behind the (TI has InstaSPIN & InstaMOTION, ST has their own motor control SDK for STM32 & I'm not sure about Microchip & Infineon) but more content on the community that focuses on the technical side of things (deep-dives, webinars etc) would be pretty nice to have!

     

    Sadly, I missed out on the TI Motor Drive Bundle, MotorWare, Personal Trainer road test, but something along the lines of this will be great! I was going through the reviews, and not only did they get a complete kit to test (C2000 Launchpad, Driver board & Motor), but they got a personal trainer from TI, which is definitely a step ahead of searching for answers on the TI E2E Community Forum.
