7.5 Mounting of main electric motor

In many cases the electric motor(s) are delivered separately. The following
instructions are applicable for these cases only.
Unsecured motor can fall
Risk to life or serious injury or material damage.
▶ Do not stand under hanging load.
▶ Use all lifting ears when the electric motor is hanging free.
▶ Earbolts must be screwed in right up to their supporting surface and tightly
fastened
▶ Use only lifting equipment adapted to the weight on the rating plate.
▶ No hands between electric motor and bellhousing during assembly.
▶ If necessary, use suitable, sufficiently-sized transport equipment such as lifting
straps (EN1492-1)
1. Unpack the electric motor
Unpack the electric motor. Check the electric motor for external damage
and that all rating plate data are the same as in the attached technical
documentation.
2. Check the shaft coupling
Check that the axial shaft coupling for external damage and that the locking
screw is tightened.
3. Lift the electric motor
Two separate lifting equipments are needed to lift the electric motor.
Lift the electric motor horizontally with both lifting equipments.
Do not use the motor shaft as lifting point!
– When on a reasonable height, lower one of the lifting equipment until the motor
is hanging vertically.
– If needed lower the motor to a stable frame of plank or similar resting on the
electric motor flange.
– If needed reconnect one lifting equipment for vertical lifting of the electric
motor. The straps must be separated to avoid force from the straps to the fan
cover. (Fig. 21)
Never let the electric motor stand on the shaft coupling!
