For applications that require minimum power consumption using AC Induction Motors (ACIM) PowerWarp presents a solution. By simply setting an enable flag in InstaSPIN-FOC, the FAST estimator will recalculate the magnetizing current, so that the minimum current is used to produce the torque needed for a given load and speed.
The PowerWarp software has the greatest effect on motor efficiency at partial loads. However, as a result of de-fluxing the motor, the ability of the control system to respond to sudden transient conditions is diminished. However, flux angle tracking is not affected by this phenomenon
As shown in Figure 17-1, PowerWarp software when enabled, acts on the magnetizing current provided by the FAST estimator as highlighted. This magnetizing current is referred as Irated in the diagram.
