General Electric NEMA/IEC AC Motors
Energy $aver® - TEFC Severe Duty
GE
has been manufacturing premium efficient motors since the late 1970s. The latest
Energy $aver design meets EISAct (Energy Independence & Security
Act 2007) efficiency levels (which are based on NEMA Premium® MG1 table
12-12). Other standards and certifications include CSA-Motors and C-390, UL
Component & Insulation System Recognition and CE mark for 320 frame and
below.
Industries: Oil & Gas, Power & Energy, Water & Wastewater, Cement,
Pulp & Paper, Metals, Mining, Chemical.
Features and Benefits
GEGARD2000 Insulation System
The GEGARD1800 insulation system exceeds
NEMA MG1-31 standards for motors operating on inverter power at 460 or
575 volts. Other inverter capabilities
include a 10:1 variable torque speed range along with a 4:1 constant torque.
Energy Savings
The Energy $aver TEFC meets US Government EISAct
efficiency levels and also meets NEMA Premium efficiency levels (NEMA MG1
table 12-12). This motor design
has been tested per IEEE 112 Method B to ensure those efficiencies are met.
Because of this, energy savings vs. a Pre-EPAct or EPAct motor are significant.
For instance, a 100 HP PreEPAct 4 Pole TEFC motor operating 8760 hrs/yr at
a rate of $0.06/kWH replaced with a similar Energy $aver TEFC-SD will save
you over $1800 every year in energy costs!
Severe Duty
The Energy $aver frame, endshields, fan cover
and conduit box are a rugged cast iron construction. It includes
a recessed steel reinforced neoprene sling
to minimize contaminants from entering the bearing cavity.
Additional HP is available at 1.15-service factor for severe applications.
A non-hygroscopic,
anti-fungus Class F insulation is included, with an 80° C
(NEMA B) temperature rise. A 0.08 IPS vibration meets the IEEE
841 Standard and
Y-Start/Delta Runs
are designed for 210-320 motor frames.
- 320 Frames and below - 200/400 V @
50 Hz
- 286 Frames and below - 200 V @ 60 Hz
