Description
The leakage inductive reactance 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 can be
described by an inductance, namely, leakage inductance. This parameter can be
obtained by static auto‑tuning or dynamic auto‑tuning of the motor.
F1-09
Mutual inductive reactance of the asynchronous motor
Address:
0xF109
Min.:
0.1
Unit:
mH
Max.: 6553.5 Data type: UInt16
Default:
156.8
Change:
At stop
Value Range:
0.1 mH to 6553.5 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 interphase inductance of the stator, which is the reactance between two
phases of the stator. The other is the inductance between the stator and the
rotor. The former does not change with the rotation of the rotor, while the latter
changes accordingly with the rotation of the rotor.
Both types of mutual inductance can be obtained through static or dynamic
motor auto‑tuning.
F1-10
Asynchronous motor no-load current
Address:
0xF10A
Min.:
0.1
Unit:
A
Max.: F1‑03 Data type: UInt16
Default:
4.2
Change:
At stop
Value Range:
0.1 A to F1‑03 (Rated motor current)
Description
This parameter defines the current passing through the three‑phase winding of
the stator when the motor is running without load. It can be obtained by dynamic
auto‑tuning of the motor.
