BOOSTXL-DRV8320RS: motor interference

Part Number: BOOSTXL-DRV8320RS


I try to use MotorSDK to control my motor and it is in good condition.

But I want to detect 300RPM~1450RPM torque motor, but when the motor is disturbed, the robustness is very poor.
Is there any good way to robustness?
When interference occurs or the rotor is blocked, the torque can be increased by pressurizing (increasing current).

I test 3000RPM I can test my torque to 0.3 N-m.
When motor 1000RPM the torque increase slowly, but the value will be around 0.2N-m, it cannot reach higher torque.
