Information about electromagnetic fields
WARNING
Electromagnetic fields
Electromagnetic fields are generated by the operation of electrical power engineering
installations such as transformers, drives, or motors.
Electromagnetic fields can interfere with electronic devices, causing them to malfunction.
For example, the operation of heart pacemakers can be impaired, potentially leading to
personal harm or even death. It is therefore forbidden for persons with heart pacemakers to
enter these areas.
The plant operator is responsible for taking appropriate measures (labels and hazard
warnings) to adequately protect operating personnel and others against any possible risk.
● Observe the relevant nationally applicable health and safety regulations. In Germany,
"electromagnetic fields" are subject to regulations BGV B11 and BGR B11 stipulated by
the German statutory industrial accident insurance institution.
● Display adequate hazard warning notices.
● Place barriers around hazardous areas.
● Take measures, by using shields, for example, to reduce electromagnetic fields at their
source.

3.4.5 Cooling
Natural cooling
The rated data only applies when the ambient temperature does not exceed 40 °C (104 °F)
as a result of the installation conditions.
To ensure sufficient cooling, a minimum clearance of 100 mm from adjacent components
must be observed on three sides.

Description
3.4 Structure
1FT7 synchronous motors
Operating Instructions, 04/2010, 610.40075.40b 19
Forced ventilation
This cooling method is implemented by means of a separate ventilation module equipped
with a ventilator that operates independently of the motor. The fan is available with degree of
protection IP54.
NOTICE
Steps must be taken to ensure that the motor is always operated in conjunction with the
separately driven fan.
The motors must be arranged in such a way that the cooling air can flow in and out without
obstruction and that the minimum clearance s between the inlet/outlet air openings and
adjacent components is maintained (see "Minimum clearance" diagram below).
V
s A minimum clearance of 30 mm applies for AH 63 and AH 80.
A minimum clearance of 50 mm applies for AH 100.
Figure 3-2 Minimum clearance s
Steps must be taken to ensure that hot outlet air cannot be drawn back into the system. The
direction of air flow is from the non-drive end (NDE) to the drive end (DE). The fan may only
be operated with normal ambient air, as air containing chemical or conductive impurities
could cause the fan to fail prematurely. Deposits from contaminated air could result in poor
heat transfer at the motor or could cause the cooling-air duct to become clogged, leading to
an overheated motor.
WARNING
Danger of being drawn into the machine
There is a danger of being drawn into the machine (by means of hair, ties, loose items, etc.)
at the air inlet. Suitable protective measures must be taken to guard against this: wear a
hairnet, take off ties, keep clear of the intake area, etc.

Water cooling
The motor can only be operated in a closed cooling-water circuit with a cooling unit. The
motor is connected to the cooling circuit by means of two female threads at the rear of the
motor. The inlet and outlet connections can be freely selected.

Minimum cooling water inlet temperature Tcooling > Tambient - 5 K
Maximum cooling water inlet temperature, without
derating
≤ 30 °C, higher values will cause derating
Only water with an appropriate quantity of additives to protect against corrosion and
minimize the growth of algae can be used as a coolant. Other coolants (e.g. cooling-
lubricating medium, water-oil mixtures with 10% oil and higher) may result in derating.
If there is a risk of frost, preventive measures must be taken during operation, storage, and
transportation (anti-freeze, emptying the cooling circuit and blowing it out with air, etc.). Use
and concentration of the anti-freeze according to information provided by the manufacturer.
Different anti-freeze agents should not be mixed.
A filter (100 µm) must be installed in the inlet pipe to protect the motor against
contamination. Pipes and valves can be made out of brass, stainless steel, or plastic.
However, if different materials are used in close proximity to one another, then the insulation
rating must be taken into account, which is why zinc must not be used in cooling circuits.
If a restrictor is needed to limit the flow of coolant, it is best to install it downstream of the
motor. It must not be installed directly in front of the inlet because the effects of cavitation
may damage the motor.
The values specified for the cooling water correspond to the requirements for a closed
cooling circuit. Not all of the specified concentrations will occur in the cooling water at the
same time.
