Product Overview Advanced design motors sharing the same stator windings, the same rotors, the same housings, the same flanges, the same performance, and the majority of technical solutions with its twin brake motor series (HBZ, HEZ, HBF, and HBV). The generous electromagnetic sizing allow to achieve high efficiency values complying with different energy saving regulations: – Efficiency class IIE2 - E3 (ErP); The electric design (terminal block, name plate, etc.) has been studied to comply, as standard, also with NEMA MG1-12 for the maximum application flexibility and facility. The strength...
