Warning
Only the intended openings, eyebolts
and lifting pin on the base plates may
be used for transporting motor sets.
Always pay attention to the carrying
capacity of the lifting device. Motor sets
must not be lifted by attachment to the
individual motors.
NOTE: The motors should not be lifted
using the centre holes on the shaft DE and
NDE, because the weight of the motor
shall harm the bearing and reduce its
performance and operational life.
Check the packing of the motor on arrival
and in case any damage is observed, please
report to the nearest Siemens ofce.
Make sure that the right type of motor as
ordered has arrived. The motor nameplate
provides relevant information.
If the motor is not installed immediately, it
should be stored in a dry and vibration free
room.
Caution
(Environmental Protection)
Disposal of packing material: On
unpacking the motors, the packing
material shall be disposed as per the
Local / Statutory requirements.
Special attention should be given to
Polythene bags, thermocole packing
and nylon straps etc., which are not
biodegradable.
3.2 Mounting
All standard motors are suitable for
horizontal as well as vertical mounting. i.e.
Standard foot mounted motors can be used
in IM-B3, B6, B7, B8, V5, V6 constructions
or ange-mounted motor can be used
in IM-B5, V1, and V3 constructions. Face
mounted motors can be used in IMB14,
IMV18 and IMV19 constructions. For
installation of foot mounted motors on a
wall, adequate support should be provided
to the mounting feet. The motor must be
securely installed to a rigid foundation or
mounting surface to minimize vibration
and maintain alignment between the
motor and shaft load. Failure to provide
a proper mounting surface may cause
vibration, misalignment and bearing
damage.
After installation is complete and
accurate alignment of the motor and
load is accomplished, the base should be
grouted to the foundation to maintain
this alignment. All motors which have
a shaft extension pointing upwards (V6
construction) must have a means (provided
by the user) of preventing the ingress of
dust and of liquids along the shaft.
3.3 Installation
After installation, screwed-in lifting
eyebolt(s) should either be removed or
tightened down.
Check the free running of the rotor by
rotating the shaft by hand.
The shaft extension, face and spigot of
the ange of the motor are coated with
an anticorrosion agent. To remove this
coating use kerosene / thinner. Do not use
sandpaper or scraper.
Before mounting the motor, see that the
motor feet are properly cleaned.
The transmission elements to be tted to
the motor should be dynamically balanced.
Please note that the rotors of the motors
are dynamically balanced with half key
inserted in the shaft extension of the
