Hi all,
i have some problems with a 3KW BLDC in my underwater scooter. at the moment the motor is not very efficient. i have maximum current and very poor speed, and the motor gets hot.
one problem may be wrong parameters for FOC or PID (the other problem is the propeller i think :) )
the motor is configured in FOC mode (with wizzard) and controlled by a custom app by setting duty cycle. which parameters have influence of the motor power ? speed tracker ki/kp or under PID controller kp,ki,kd ? i hope that there is some controller oscillation with is the reason for my bad efficiency
Thanks
Georg
