4.2 - Operating Conditions

In general electric motors are designed for
operation up to an altitude of 1000m above
sea level for an ambient temperature ranging
from -20ºC to 40ºC. Any variation is stated
on the nameplate.
The recommended installation distance be-
tween air inlet from the motor and the wall
should be at least ¼ of the air inlet diameter.
A person should have enough room to carry
out cleaning services.
Machines that are cooled with ambient air,
air inlet screens must be cleaned at regular
intervals so as to ensure free air circulation.
Warm air can not return to the motor.
- For vertically mounted motors with air inlet
on top, the air opening must be protected by
a proper cover so as to avoid dropping of
foreign materials on the motors.
- Considering that direct sun heat causes
increase in temperature, externally installed
motors should be always protected against
weathering.

ODP MOTORS – Open motors (IP21, IP23)
are machines designed for operation in clean,
dry areas, with enough air circulation for
proper cooling. These motors should never
be used in areas with flammable materials.
Open motors may cause sparks and release
cast particles under any eventual insulation
failure (short-circuit).
TEFC MOTORS – Totally enclosed motors
are machines suitable to operate in areas

with moisture, dirt and/or corrosive materials
either in enclosed or open environments.
4.3 - Foundation
Motors provided with feet must be installed
on solid foundations to avoid excessive
vibrations.
All motors must be fully fixed and aligned.
The purchaser is fully responsible for the
foundation.
Metal parts must be painted to avoid
corrosion.
The foundation
sufficiently strong to support any shock. It
must be designed in such a way to stop any
vibration originated from resonance.
Note: Considering that rotation direction is
important for correct operation, then check
it carefully before connecting motor to the
load.
4.4 - Drain Holes
Make sure drains are placed at the lower motor
position when the mounting configuration
differs from that specified on the motor
purchase order.
4.5 – Balance
w
hen special balance is
required
All motors are dynamically balanced at the
factory with half key.
Transmission elements such as pulleys, cou-
plings etc must be dynamically balanced with
half key before installation.
Use always appropriate tools for installation
and removal.
4.6 – Alignment

Make sure that the motor mounting devices
do not allow modifications on the alignment
and further damages to the bearings.
