Armstrong HE Series motors are general purpose polyphase squirrel cage induction motors meeting all required NEMA and IEEE standards. In addition to numerous in-factory sampling motor tests to verify and improve designs, motors have been tested at Hydro-Quebec’s independent motor testing laboratory in Canada. Armstrong HE Series TEFC motors from 1 hp to 100 hp currently meet or exceed the efficiency requirements of the US Energy Policy Act of 1992 (EPAct) and Natural Resource Canada Standards (NRCan).
