The inverter measures rotor resistance, rotor resistance and leakage inductive reactance
in sequence but does not measure the mutual inductive reactance and no-load current of
the motor, which can be calculated by the user based on the motor nameplate. The motor
nameplate parameters used in the calculation include rated voltage U, rated current l, rated
frequency ƒ and power factor η:
The calculation methods of the no-load current and mutual inductive reactance of the motor are
described below. “Lσ” refers to mutual inductive reactance of the motor.
