Lafert N.A’s HPS Series permanent magnet (PM) synchronous AC motors deliver IE4 Super Premium energy efficiency while reducing motor size and weight by up to 50 percent. The HPS Series combines the mechanical design of the standard induction motor with the high performance and energy efficiency of the brushless servo motor design. This uniquely engineered product was inspired and made possible through decades of Lafert experience and expertise in the design and manufacture of both motor designs.



The target of the HPS Series is motor-driven HVACR equipment such as pumps, fans, compressors and blowers where system size, weight or operating costs are key design considerations. The IE4 Super Premium energy efficiency levels achieved by HPS Series motors deliver significant energy savings (up to 14%) when compared to EISA Premium AC motors. The energy efficient performance of HPS Series motors allows equipment manufacturers to exceed minimum energy performance standards (MEPS) while reducing ownership costs.



Additionally, the HPI Series combines each high performance HPS Series permanent magnet motor with a matched variable frequency drives (VFD) design to produce seamlessly integrated motor and drive solutions. The onboard Lafert drive technology and control interface, deliver optimized system performance and energy efficiency without costly and time-consuming integration of discrete motor and drive systems. Lafert will be located at Booth E-121050 during IMTS 2018.
