Earlier we posted questions on motor startup, thanks for the help. Finally we could start the vehicle/ motor successfully with BLDC mode during start up. We are using Lab 11e for our prototype testing.
Now the motor starts all the time properly, but it produces noise while in BLDC mode, in FAST mode it is very quiet. Need your help in addressing the noise issue.
Enclosing the video, where is motor starts with BLDC then transition to FAST.
Motor : Sinewave / PMSM.
gHall_speed_BldcToFast_high_pu : 50rpm
gHall_speed_FastToBldc_low_pu : 30rpm
Ki, Kp are tuned as per lab 5a.
