Installation and maintenance instruction
Fläkt Woods three phase asyncronous motor
Manufacturer: ABB
Use
Operating conditions
The machines are intended for use in industrial drive
applications.
Normal ambient temperature limits are -25 °C to +40 °C.
Maximum altitude 1000 m above sea level.
Safety considerations
The machine is intended for installation and used by
qualified personnel, familiar with relevant safety
requirements.
Safety equipment necessary for the prevention of
accidents at the installation and operating site must be
provided in accordance with the local regulations.
Points to observe
1. Do not use the machine to step on
2. The temperature of the outer casing of the machine
may be hot to the touch during normal operation.
3. Some special machine applications require special
instructions (e.g. using frequency converter supplies)
4. Lifting lugs must only be used for lifting the motor.
They must not be used to lift the motor when it is
attached to other equipment.
Handling
Operating conditions
The machine should always be stored indoors, in dry,
vibration free and dust free conditions.
Unprotected machined surfaces (shaft-ends and flanges)
should protected with anti-corrosive paint.
It is recommended that shafts be rotated periodically by
hand to prevent grease migration.
Anti condensation heaters, if fitted, should preferably be
energised.
The characteristics of electrolytic capacitors, if fitted to
single-phase motors, will require “reforming” following
periods of storage exceeding 1-2 years.
Contact ABB Sales Office for details.
Transportation
Machines fitted with cylindrical-roller and/or angular
contact bearings must be fitted with locking devices
during transport.
Lifting
Only lift the motor using the lifting lugs.
The center of gravity of motors with the same frame may

Small motors with supply current
directly switched by thermally sensitive
switches can start automatically.
vary due to different outputs, mounting arrangements and
auxiliary equipment.
Check that eyebolts or the lifting eyes integrated with the
motor frame are undamaged before lifting. Damaged
lifting eyes must not be used.
Lifting eyebolts must be tightened before lifting. If needed
the position of the eyebolt must be adjusted with suitable
washers.
Ensure that proper lifting equipment is used and that the
sizes of the hooks are suitable for the lifting lugs.
Care must be taken not to damage auxiliary equipment and
cables attached to the motor.direction of rotation is accor-
ding to the arrow marked on the machine.
Machine weights
Total machine weight can vary within the same frame size
(center height) depending on different output, mounting
arrangements and added features.
The following table shows estimated maximum weights
for machines in their basic versions as a function of frame
material.
On machines weighting more than 25 kg, the actual weight
is stated on the rating plate.
Installation
Cooling
Normal ambient temperatures should not exceed 40 °C
(marine standard 50°C) if standard performance is to be
achieve. Check that the motor has sufficient airflow.
Ensure that no nearby equipment or surfaces radiate
additional heat to the motor. For more information about
higher ambient temperatures and cooling, see “the Motor
Guide” or contact ABB Sales Office.
