Enclosure
The NORD standard motors are provided with Totally
Enclosed Fan-Cooled (TEFC) with an IP55 enclosure
rating. Other enclosures are available, including
Totally Enclosed Non-Ventilated (TENV), Totally
Enclosed Blower-Cooled (TEBC), and IP66.
The motor integral cooling fan provides proper air
fl ow in either direction of rotation. The IEC cooling
classifi cation is IC 411 according to IEC 60034-6.

Protective Features
All NORD Motors and Speed Reducers are constructed
to provide a high degree of protection against wet
and severe environments. NORD Motors and Speed
Reducers are extremely well sealed against moisture
ingress and use corrosion and moisture resistant
components. NORD has recently made many
enhancements in the motor and gear units standard
construction to provide improved environmental
protection. Many of the standard protection features
of the NORD units are only available at an additional
cost from other motor and gear drive suppliers. NORD
designs all gearmotors, speed reducers and motors
for installation in harsh industrial, commercial and
municipal installation environments.
