Depending on the position of the primary part of the motor with regard to
the secondary part of the motor, different inductance values can be
observed when the leakage inductance is measured. The values are
fluctuating between a minimum and a maximum value.
•
The minimum value is relevant for the direct-axis inductance of the
motor (L
L(U-V)
).
•
The maximum value is relevant for the quadrature-axis inductance of
the motor (L
Q(U-V)
).
Note: Correct values can only be determined when the motor is in
standstill!
The value for the direct-axis inductance of motor contained in the
completed form "Output Data for Synchronous Motors" has to be used for
calculation as follows:
