Hello,
I am using the driver Steval-ihm023v3 to run a PMSM. Previously, I used one of the TI low voltage drivers and ran my motor. Now I am using the low voltage configuration of the Steval-ihm023v3, namely "35V only", but I see weird behavior when I run the motor.
I am doing FOC, so when I have a command "Iq", I expect the motor to reach the highest speed , allowable with the input voltage of course, but the motor reaches 75% of the maximum speed and then suddenly it stops or rotates with a weird noise. For example if I run the motor with 25V, the maximum speed should be 900rpm, but the motor reaches 600rpm and whatever I choose for the PI gains of current controllers, it can't reach 900rpm. My guess is that the protection of the gate driver is playing a role in this. Could anyone please share their experience with me?
Regards,
