U.S. Dept. of Energy Integral Horsepower Motor Rule
Effective June 1, 2016
The United States Department of Energy passed a final rule
in 2014, that covers 1 -500 HP (0.75 -370 KW) 3-phase
electric motors. The new law will supersede the Energy
Independence & Security Act (EISA) of 2007 and become
effective June 1, 2016. For reference and complete
wording of the law, refer to:
electric_motors_ecs_final_rule.pdf
The new legislation broadens the number of motor types
covered and closes most of the loopholes that permitted
exceptions in both EPAct 1992 and EISA 2007 legislation.
In essence, most 3-phase industrial motors manufactured
will be required to meet the efficiencies listed in NEMA
MG-1, table 12-12 (reference NEMA Premium® efficiency).
Additional motor types covered include, but are not
limited to:
n
201-500 HP (previously 1 – 200 HP)
n
Footless (C-face & D-flange)
n
Vertical (HP & LP)
n
8-pole (900 RPM)
n
Brakemotors (integral and add-on)
n
Motors with customer special shafts, flanges
and mountings
n
IEC 100 frame
Motors that are not covered by mandated efficiency
regulations are:
n
Multi-speed (SD10MS)
n
Inverter duty only (RGZVESDI)

2015 Low Voltage AC Motors Selection and Pricing Guide
The majority of Siemens low voltage motors listed in this price guide currently meet, or
exceed, the June 1, 2016 mandatory regulations. Industry-leading, die cast copper rotor
motors, exceed all efficiency requirements.
Vertical, solid shaft, P-base (HP & LP) motors will be
available in the near future, with NEMA Premium®
efficiencies as standard.
