The leakage inductance of the asynchronous motor is caused by the
leakage flux of motor winding. In the winding of the motor, when current
is introduced, magnetic flux will be generated. The magnetic flux can be
divided into two parts based on the path: main flux and leakage flux. The
leakage flux is the leakage inductance. This parameter can be obtained by
static auto‑tuning or dynamic auto‑tuning of the motor.

When the current in one coil of the motor changes, induced EMF is
generated in the coil adjacent to it. This mutually induced EMF can be
expressed by mutual inductance.
The mutual inductance of a motor can be roughly divided into two types.
One is the inter‑phase inductance of the stator or rotor, which is the
reactance between two phases of the stator or rotor. The other is the
inductance between the stator and the rotor. The inductance of the first
type does not change with the rotation of the rotor, whereas the
inductance of the second type changes accordingly with the rotation of
the rotor.
This parameter can be obtained by dynamic auto‑tuning of the motor.

This parameter indicates the current that passes through the three‑phase
winding of the stator during no‑load operation of the asynchronous
motor. The parameter can be obtained by dynamic motor auto‑tuning.

This parameter defines the inductance of the main pole axis (longitudinal
axis) of the synchronous motor.

This parameter defines the inductance of the center line (quadrature axis)
between the adjacent pole axes of the synchronous motor rotor.

This parameter defines the number of pulses generated per revolution of
the encoder disk. In the feedback vector control (FVC) mode, set this
parameter properly; otherwise, the motor will malfunction.
