Motor Control Tuneup
Motor Control Tuneup: Equivalent Circuit
The equivalent circuit for the induction motor used in the motor control tune-up is:
R1
R2
inner
Lsigma outer
R2 outer
Lsigma
Bridge Flux
Flux Saturation
Curve
V
I
The motor elementals and flux saturation curve will be measured for the phase
combinations of AB and BC. After both sets of measurements are completed the
balance of each phase pair will be compared for each motor elemental and saturation
curve data point. The deviation of R1, R2, saturation curve should be less than 10%
and for Lsigma less than 25%. The averages of the motor elementals and saturation
curve are saved in the engineering parameters (At_xxx) and used in the recalculation
of the motor control tune-up values.
