The Lafert HP series technology takes the latest in AC induction motor technology and combines it with established brushless permanent magnet otor principles to create a motor that can produce savings of up to 80% in energy costs, while offering the capability of significant frame size reductions and weight savings of approximately 50%. Integrating these technologies provides substantial efficiency advantages over conventional AC induction motors. Stator currents are lower, generating lower losses due to low current demand, which in turn reduces temperature in the windings and bearings. These low-temperature rises can eliminate the need for a cooling fan and its related losses, thereby allowing higher running speeds and extending bearing life. The HP series is suited for applications involving pumps, fans and compressors. The range includes single-phase power ratings of 0.75 kW to 2.2 kW and three-phase supply versions of 0.75 kW to 22 kW in both 50 Hz and 60 Hz applications. These units are available with a built-in drive or as a stand-alone unit that is compatible with most other manufacturer’s drives.
