2 Two new high-performance motor and drive packages For industrial applications lide 2 standard motor + special rotor standard drive + new software A new revolutionary Drive Package! The High Output package Power range from 1 to 350 kw Powerful, yet highly compact motor with up to two frame sizes smaller than conventional motor Enables cost effective machine designs The IE4 uper Premium Efficiency package Power range from 11 to 200 kw Energy losses reduced by up to 40% Compliant to the upcoming efficiency class IE4 Payback time less than two years from energy savings alone Both packages are based on perfectly controlled synchronous motor technology without permanent magnets materials. Optimized for VD operation, they combine motor, drive and advanced software into complete solutions. 9/2/2011

3 New revolutionary motor and drive package For industrial applications imilar functionality compared to traditional induction motor and drive package uitable for general purpose industrial applications such as pumps, fans and compressors ame stator technology with induction motor combined with novel synchronous reluctance rotor Performance comparable to permanent magnet motors, but without magnets Optimized for VD operation not suitable for direct-online fixed speed operation 9/2/2011 lide 3

K. Kostko 1923 (original patent) (e) Vagati and Fratta 1980s & 1990s

6 ynchronous eluctance Technology Design concept ingle sheet of punched electrical steel The sheets stack to a complete rotor body. Can either be stacked on a pre-assembly piece or direct on the shaft. Mounting the rotor body on a shaft. The rotor will be balanced after shaft assembly. The rotor body inset in a stator. A standard stator 4 pole design is used but with adapted winding. ABB BU LV Motors May, 2009 lide 6
