Hi,
I use the FOC demo code to drive my motor .My motor's nominal speed is 30000rpm.In my applicaiton, I got the max speed is 23900rpm though I added the speed command ,it held 23900rpm.
Does the SpeedPi.PiMax or other parameter limit the max speed? And how to change the code to get a higher speed of the motor.
Best!

Hi Liang Xiao,
do you get any error messages from the FOC software?
I will need to check if there is any limitation to the motor speed, coming from the software.

Hi Liang Xiao,
the maximal speed of the FOC SW is 32768 rpm.
You could try to increase the number of pol pairs in the FOC SW, this could theoretically also increase your motor speed.
What is the voltage rating of your motor?

Hello Fiz,
When I using Foc program,the motor cant reach the reference speed.
And I use your advice that increasing the pairs,but is useless.
Please tell me how to solve the program.
I am hoping your answer,thank you vary much.

Hey @User17952 ,
Try to increase the MAX Speed current to increase the RPM. Otherwise kindly let me know the motor BEMF constant when motor running at 23K RPM.
Best Regards,
Rohit
