655.35
Data type: UInt16
Default: Model dependent Change:
At stop
Value Range:
0.01 mH to 655.35 mH
Description
The asynchronous motor leakage inductance 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.

Asynchronous motor mutual inductance

Unit:
mH
Max.: 655.35 Data type: UInt16
Default: Model dependent Change:
At stop
Value Range:
0.01 mH to 655.35 mH
Description
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
inductive reactance of the stator or rotor, that is, the inductance between two phases of the stator;
and the other is the inductive reactance between the stator and the rotor. The inductive reactance of
the first type does not change with the rotation of the rotor, while that of the second type changes
accordingly with the rotation of the rotor. This parameter can be obtained by dynamic auto-tuning of
the motor.
