conventional motor� Enables cost effective machine designs

The IE4 Super 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 VSD operation, they combine motor, drive and advanced software into complete solutions.

New revolutionary motor and drive package

� Similar functionality compared to traditional induction motor and drive package

� Suitable for general purpose industrial applications such as pumps, fans and compressors

� Same stator technology with induction motor combined with novel synchronous reluctance rotor

For industrial applications

with novel synchronous reluctance rotor

� Performance comparable to permanent magnet motors, but without magnets

� Optimized for VSD operation – not suitable for direct-on-line fixed speed operation
