Other Parts Discussed in Thread: MOTORWARE
Hello, I have been working on running a hobby motor (Amazon.com: HobbyStar 550 Brushless Sensorless Motor, 4-Pole, 4300KV, 5.0mm Shaft, for 1/10 RC Short Course Truck : Toys & Games) using InstaSPIN-FOC, Launchxl-28069m, and a boostxl-drv801. Currently I am working on running project 2a, and it is the first project I have tried to run. I have not edited user.h, I just built the project in Code Composer Studio, copied it to the Universal GUI folder, and renamed it to appProgram.out, then ran the universal GUI executable. I was able to identify and run the motor; however, there a few things which are not as I expected.
1. The InstaSPIN motor id is not calculating the Rs value given by the motor's datasheet. The anticipated value was .06 ohms, and the InstaSPIN calculated value was about .026 ohms as can be seen in the screen shot below:
2. I pressed run again after motor identification was finished, and I tried setting the ref speed and max accel from 100 and 200 to 5000 and 1000 respectively. Instead of running smoothly the motor turned in stops and starts, and was not able to reach the reference speed.
Please feel free to leave me any thoughts or advice, and I would be happy to answer any other questions you might have to help solve this issue. Thank you!
