1. General information
To avoid damage to the motors and the equipment they
drive, follow the instructions in the operating and main-
tenance manual. To avoid danger, observe in particular
the safety instructions which are provided separately.
Since the operating and maintenance manual, for the
sake of brevity, cannot provide specific information for
all conceivable special applications and areas with spe-
cial requirements, the operator needs to take appropri-
ate precautions during assembly.
Also observe the applicable information from
the operating and maintenance manual for
three-phase asynchronous motors!
2. Description
The motors conform to IEC 60034-1, DIN EN 60034-1
(VDE 0530-1) and additional applicable DIN standards.
Separate additional instructions apply to the following
motor modifications:
– Brake motors
– Motors with separately driven fan units
– Motors with attached transmitters
3. IP code
The IP code of each motor is indicated on its rating
plate; attached additional devices may have different
IP codes from the motor; this needs to be taken into ac-
count when installing the motor. If setting up motors
(IP code ≥ IP 44) outdoors, care must be taken to
protect the motors from the immediate effects of the
weather (freezing of the fan if exposed directly to rain,
snow and ice).
4. Configurations
The configuration of each motor is indicated on its
rating plate. Use in configurations other than those
specified is only permitted after the manufacturer has
given permission and the motor has, if necessary, been
converted according to the manufacturer's instructions.
The operator must ensure, especially for configurations
with a vertical shaft, that foreign objects cannot fall into
the fan cover.
5. Transport and storage
The motors should, if possible, only be stored in en-
closed, dry spaces. Outdoor storage under a roof is only
permissible for a short time and must include protection
from adverse environmental effects. Motors must also
be protected from mechanical damage. Do not move or
store motors resting on their fan covers.
For transport, use the eye bolts on the motors in
combination with suitable lifting accessories. The eye
bolts may only be used to hoist the motor without any
attached accessories such as base plates, gear boxes
etc. If eye bolts are removed after installation, seal the
threaded holes permanently in accordance with the IP
code.
6. Installation and assembly
During the regular operation of electric motors, surface
temperatures of over 100°C can occur; for this reason,
the motors must be protected from accidental contact if
they are located in accessible areas. No temperature-
sensitive components may be attached or kept adjacent
to the motor. Keep ventilation openings and cooling
fins unobstructed, and observe the minimum distances
specified in the dimension sheets to ensure that the
cooling air can flow freely. Ensure that the warm cooling
medium that has been expelled is not drawn in again.
For configurations IMB14 and IMB34, make sure not
to exceed the maximum usable depth of engagement
specified in the catalogue (damage to the coil!). The
feather key in the shaft is protected by the shaft pro-
tection sleeve for transport and storage only; do not
put the motor into operation or perform a test run with
the feather key protected only by the shaft protection
sleeve, due to the risk of the feather key being ejected.
When mounting the transmission element (such as a
coupling, pinion, or belt pulley), use mounting devices or
heat up the part to be mounted. For mounting, the shaft
extensions have centring devices with threaded holes in
accordance with DIN 332 part 2. Ensure that transmis-
sion elements cannot collide with the shaft; otherwise,
the shaft, bearing and other parts of the motor may be
damaged. All elements that will be attached to the shaft
extension require careful dynamic balancing according
to the balancing system of the motor (full/half feather
key). The rotors of the motors are balanced with a half
key; this is indicated on the rating plate with the letter H
after the type designation. Motors with the letter F after
the type designation are balanced with a full feather
key. The motors must be installed free from vibration, if
possible. Special instructions apply to motors in low-
vibration configurations. After assembly is complete,
the operator must make sure that movable parts are
protected and that operational safety is ensured.
If the motor is coupled directly to the machine it drives,
the alignment must be particularly precise. The axes of
both machines must be in line. To adjust the axis height
of the machine being driven, use appropriate shimming.
Belt drives put relatively large radial loads on the motor.
With regard to belt drive sizing, in addition to following
the regulations and calculation programs of the belt
manufacturers, also make sure that belt pull and belt
pre-tension do not exceed the maximum radial force
at the shaft extension of the motor according to our
specifications. During assembly, the belt pre-tension in
particular must be adjusted exactly according to the belt
manufacturer's instructions.
