Dear Mahad,

Can you be more specific and provide more information on your case?

Best,

Actually my task is to find the maximum current of a BLDC motor also taking into account the start-up current. Using the motor control and driver board I have the predefined data when the 10A current is applied at 500rpm speed:

I get these values:

Stator resistance = 50 mΩ

Inductance = 76 μH

Now how can I calculate the desired value of the current? As of now consider only the start-up current.
