Ah sorry I should have clarified, not motor inertia but the overall total vehicle inertia. At least the way that ASI has written their sensorless self start firmware it runs open loop at a steadily increasing RPM before switching over to closed loop control. So if it tries initially to ramp up the speed faster than the motor torque can actually accelerate the vehicle mass, then it will tend to shudder.
There are surely many more optimal sensorless self starting algorithms possible! But this is what we've got to work with here. Would love it of course if Lebowski was head of ASI's firmware team
Are they hiring ? :lol:
