Three-phase synchronous motor English
The motor shaft and the connection surfaces must be protected against corrosion. The motor may only be
transported with a shaft protection cover; damage to the motor shaft must be avoided.
Bearing lock (for motors with cylinder roller bearings only):
On motors with cylinder roller bearings, the runner must be blocked at the end of the
shaft in order to prevent damage during transit.
The transport protector must be used every time the machine is moved.
If this lock no longer can be used due to mounting of a drive element, other suitable
means must be employed for axial fixing of the rotor for transport.
Intermediate storage:
If a motor is not to be commissioned immediately after delivery, it should be stored inside a building in a
dry, dust-free and low-vibration room (V
eff
≤ 0.2mm/s).
The electric motors should not be stored longer than 2 years at a consistent temperature which is within
the temperature range of -15 to +60 °C. Elevated storage temperatures within the framework of the
working temperature accelerate the rate at which seals and bearing grease deteriorate and therefore
have a negative impact on the service life even before the unit has been commissioned. Direct exposure
to incident solar radiation, UV light and ozone also lead to an ageing of the gaskets and must be avoided!
Please note that the warranty periods commence from the date of delivery. For this reason, we
recommend that storage periods are kept to a minimum.
Should nevertheless a longer storage be necessary, the environmental conditions acc. to DIN EN 60721-
3-1 (class 1K2/1M1) have to be observed. Contrary to the DIN, an expanded temperature range of –
15 °C to + 60 °C is permitted.
2.6 Installation conditions, cooling details
For motors with water-cooling please take Section 9 into account in addition.
Surroundings:
The motor can be installed in roofed rooms complying with the degree of protection in dusty or damp
environment and under normal climatic conditions.
Unless alternative arrangements have been made, the motor is designed by default for the following
climatic conditions:
Ambient temperature 0 °C to 40 °C
Installation height ≤1000 m above sea level
The relative humidity reaches 5 % to 85 %
All other allowed application conditions have to correspond to DIN EN 60721-3-3 (class 3K3/3Z12).
It is absolutely imperative to comply with these climatic conditions when installing the unit.
Aggressive, corrosive, abrasive and plastic-dissolving solutions should be kept well away from the motor
and the air that is used to cool it.
Consultation with the motor manufacturer is essential in the case of installation outdoors.
