maxpenna 6 Posted May 7, 2012 Share Posted May 7, 2012 Hello guys, I have posted my BLDC motor control with msp430g2553 (launchpad rev1.5) on e2e TI's site. I designed the boards for simple brushless motor control formatted in boosterpack style. My goal is to test theese boards in one mounth but if you could go faster please feel free to contribute and thank you very much... I appreciate very much if you have time to grow up the project Max Quote Link to post Share on other sites
bluehash 1,580 Posted May 8, 2012 Share Posted May 8, 2012 Hi Max, Welcome to the Forums. That's great! Could you share a link with us and also pictures? What are you running - Sine/FOC? Quote Link to post Share on other sites

maxpenna 6 Posted May 8, 2012 Author Share Posted May 8, 2012 Hi Max,Welcome to the Forums. That's great! Could you share a link with us and also pictures? What are you running - Sine/FOC? I shared my CCS project folder here and also Eagle Cad project folder, I designed a boosterpack style board which purpose is to control brushless motors with hall sensors with the cheap but lovable launchpad board rev1.5. Then I had also redesigned the board with L6234PD IC from ST in order to get a smaller and easier version for etching enthusiasts. For the fw I haven't tested any motor yet but I simulated the behaviour of a running motor's hall encoder with another launchpad board (rev1.4 this time) in order to debug basilar errors and overall behaviour. I compiled a succesful version and called it v1.1. So there are many things to do the first is to build the board (one of the two) and run the fw. The fw I have produced are three: the main control motor fw, wich recognize the hall sensor sequence and switch properly high-side/low-side switches appying user controlled pwm via potentiometer and the other twos, basically both a bldc motor hall sequence generator. The first one trigger the next hall sequence via user (button) or serial interface (type h character), the other via external square input. The motor control fw v1.1 is expected to control the speed of a bldc motor with a potentiometer in open loop. Howewver the software is deeply commented... No Sine/FOC it is too complicated for msp430 I believe... Thank you for your attention! M Quote Link to post Share on other sites
