Part Number: HVPMSMMTR Tool/software: Code Composer Studio Dear All, We have noticed high amplitude oscillations in the steady-state velocity of the motor HVPMSMMTR, under both close and open loop operation. See the attached figure that shows the rotational velocity and the phase currents in pu (Base_speed = 314 rad/s and Base_current = 10 A). These data were obtained by the example HVPM_Sensored in the Build Level 3 running on a F28069, where the currents were expected to be sinusoidal. Our suspicion is that the motor has some mechanical or electrical problem. Sincerely, Grace Silva Deaecto (Please visit the site to view this file)
