High efficiency asynchronous electric motor S A Armstrong Limited

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 were 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).

For assurance of low motor vibration and noise levels, dynamic balancing on every rotor and alignment checks are performed on the production line. Only high strength, non-metallic, non-sparking external fans are used on HE Series motors to enhance the ventilation, provide additional safety, and reduce noise levels.
