PREMIUM EFFICIENCY MOTORS
GENERAL PURPOSE
The WATTSAVERe
®
line of premium efficiency
motors is
inverter capable
. LEESON’s unique
IRIS
™
voltage-spike-resistant insulation system
is standard at no extra cost. WATTSAVERe
®
motors carry a three-year warranty in general
purpose and inverter fed applications. These
motors meet or exceed most utility rebate
programs and the EPACT federally mandated
efficiency levels. The efficiency ratings have
been verified to IEEE 112B test standards by
LEESON’s NVLAP-Certified lab.
Cast iron 170 series motors can be field
modified for forced ventilation service to
extend the inverter-fed operating range and an
encoder package is stocked for closed-loop
vector inverter systems. These motors can
be converted to IEEE841 compliant using the
Custom PDQ Program. Contact LEESON.
LEESON’s Inverter Rated Insulation System (IRIS
™
)
provides superior protection against voltage spikes
induced by variable frequency drives. This
total
insulation system
protects better than spike-resistant
magnet wire alone. Specially formed phase insulation,
cushioned and sleeved connections (from the leads all
the way into the turns), and deep-penetrating, non-
hygroscopic, high temperature varnish are just a few
features contributing to extra protection. All this plus
second generation spike-resistant magnet wire.The
IRIS
™
total insulation system
is standard at no extra
cost in all LEESON stock NEMA three-phase motors,
1 HP and larger.
UL and CSA Recognition
Rugged cast iron construction
on
three phase, 1-350 HP models. These
motors share features with normal
efficiency 150 Series motors detailed on
page 18. Add an optional cast iron fan
guard for severe duty applications.
Second-generation, high temperature, spike-resistant
magnet wire
for extended motor life. Stator impregnated
with extra-heavy varnish system. 1.15 Service Factor. All
WATTSAVERe
®
motors have Class F insulation with a
Class B rise. Motors rated at 40 degrees C ambient.
One-way, corrosion resistant condensate
drains.
(TEFC models) release condensation
and moisture.
Premium efficiency motors
finished
with primer and chemical resistant
green acrylic matte enamel. IP44
enclosure protection.
Both 3/4 and full load efficiencies
are listed on
the stainless steel nameplate for your convenience
in calculating realistic energy savings. Unique serial
number identifies each motor and is stamped clearly
on the metal nameplate.
Efficiencies meet or exceed NEMA Premium
on
all WATTSAVERe
®
motors.
Modification to meet IEEE 841
available through Custom PDQ.
(See page 114). Includes addition of
watertight Inpro shaft seals, two-part
epoxy finish, and plated hardware.
Independently verified efficiencies
by the Canadian Standards
Association, an internationally
recognized testing laboratory. CSA
Report Number EEV78720-1.
All NEMA Premium motors with a “00”
suffix date coded Jan 2012 and after
are suitable for Hazardous Location
designation Class I, Div2, Group A, B, C
and D and additionally optional Class I,
Zone 2, Groups IIC, IIB, IIA. For all motors
dated coded prior to Jan 2012 - contact
Regal Beloit Canada.
Three phase models suitable
for inverter duty,
as well as
both 50 Hz and 60 Hz operation.
WATTSAVERe
®
motors comply with EISA 2007
