To get the rated magnetizing current of an ACIM motor, we can calculated from the no load current specified in a motor's name plate. In this particular example, the no load current is 0.7 A, which is usually a value provided in RMS. Usually this no load current is approximately the same as the rated magnetizing current with iq ≅ 0. The value we need to define in user.h is in maximum amplitude, so we calculate it as follows:
Now we can enter this value in user.h:
#define USER_MOTOR_MAGNETIZING_CURRENT (0.9899)
