Manufacturers of pumps and compressors will soon be able to offer their customers significant energy savings with a new motor from Lafert that employs permanent magnet motor technology. With the ability to reduce running costs by up to 80% compared to conventional AC induction motors, the new motor gives OEMs the opportunity to design pump/compressor solutions that offer their customers the potential of ongoing savings to combat energy costs that are increasing at an unprecedented rate.

In addition to the energy savings, Lafert’s new ‘HP’ (High Performance) motor achieves reductions in frame size and weight reduction thereby helping to minimise space and load penalties by as much as 50%.

The HP motor offers substantial efficiency advantages over EFF1 and even Premium efficiency motors. This is exhibited across the whole speed range and under variable load.

This is because as with the brushless, permanent magnet, motors, the rotor of the Lafert HP motor has no losses. Also, stator currents are lower, consequently generating lower losses due to low current demand (Joule effect), which in turn results in reduced temperature rise for both the windings and bearings. These low temperature rises can go on to eliminate the need for a cooling fan and its related losses. Ultimately, the sum of these minimised heat gains provides the options of higher running speeds or extended bearing life.

The new High Performance motors from Lafert are available for both single and three phase supply with ratings 0.75 – 2.2kW, 200 – 240V 50/60Hz and 0.75 – 22kW, 380 – 480V 50/60Hz, respectively.

The High Performance motor can be used with a standard servo drive when fitted with an appropriate transducer but, ideally, it should be used in conjunction with a sensorless drive developed by Lafert Drives to maximise the motors performance and superior efficiencies for the specific application.
