Three-phase-synchronous motor
English
Air cooling:
For ambient conditions, see Section 2.4 and the technical documentation that accompanies the product.
Cooling method IC 410 – Self-cooling without a fan.
The following must be observed:
•
The installation conditions must not impair thermal convection and radiation.
•
The cooling air used for forced ventilation must be able to flow in freely and the hot air must be able
to flow out freely. The hot exhaust air must not be sucked back in.
•
A clearance of at least 100 mm must be observed in relation to neighboring machine parts.
•
If installed in very dirty locations, the housing surface and airways must be cleaned regularly.
flange connection:
By connecting the motor to the mounting surface, a part of the motor loss performance is lead away via
the flange. The dimensions of the mounting surface based on their axis height are listed in
table 1. This information provides minimum values for the safe heat dissipation via the motor flange
surfaces.

Table 1: Mounting surfaces
The heat dissipation conditions approve on larger mounting surfaces. An insulated mounting of the
motors is not permitted.

Balancing, output elements, vibration
Do not subject the shaft or bearings to impacts!
On mounting and dismounting output elements, it is not permitted for any axial forces to be
applied to the motor.
The generally applicable measures for the protection of output elements against physical
contact are to be followed.
If a motor is to be commissioned without output elements, measures must be taken to
ensure the key is not flung out.
Balancing
In the optional design, the rotors are dynamically balanced with a half key (in accordance with
DIN EN 60034-14 / ISO 8821 / ISO 1940).
Output elements:
On mounting the output element, pay attention to the related type of balancing. The output elements must
themselves be balanced in accordance with ISO 1940.
Suitable jigs are always to be used for fitting or removing output elements (e.g. clutch disk, gear, pulley).
• Use the threaded hole in the end of the shaft.
• When pulling, use intermediate washers to provide the shaft with mechanical protection.
• When hoisting heat up the drive elements if required (max. permissible temperature at shaft end
150°C).
