Ian using a dyno to apply load and using B-G431B-ESC1 with a pmsm motor
SPEED: KI= 950, KP= 13767, Torque KI= 1005 reduced from 3005 earlier torque kp=82 (tuned settings)
I have attached a snapshot ,as gradually I increase load (oz-in) in steps
1) at rpm <1500 I am able to track the curve with increased load in const rpm
2) At rpm >2000 ,at higher load region the speed oscillates heavily (see snapshot attached)
I have attached the datasheet of motor from which it is clearly visible that upto 2880 RPM it can take continueous load torque of 39 oz-in
Could you suggest what could be the problem?

Dear @Ajosh.1
Welcome to the STM32 Community
Sorry for late answer.
Could you give more details to the STM32 Community about your setup -the material you use- ?
(HW and also SW: CPU(s), tools and versions, board(s), motor(s) and so on)
And more especially did you use STM32 MC tools (such as MC_suite, STM32 MC Motor Profile, STM32 MC SDK, STM32 MC Workbench, the used example, the origin of the base of your application source code, and so on)?
Best regards
