In the past, users could only roughly estimate the energy consumption of speed-controlled motors – and the payback time derived from this. With verified efficiency curves, they can now calculate the payback times of their ABB motor-drive packages with synchronous reluctance motor realistically. ABB has verified the drive packages which can be delivered from stock by performing precise measurements.
The efficiency curves cover not just individual points on the characteristic curve, but the entire speed range and are particularly suitable for pump and fan applications. Using the efficiency curves, the users can determine the energy consumption of motor-drive packages precisely and base their investment calculation on these figures.
ABB’s package efficiency points have been verified according to the methods defined in the EN 50598-2 draft standard.
