3.2 Installation, fixing
Prior to and during mounting, check that
• The motor is not damaged (e.g. the shaft sealing ring must not have sustained any damage at
all from sharp or pointed objects).
• The motor is not mounted in the danger zone of other equipment.
• The motor is used for the designated purpose
Observe nameplate details, warning labels, and signs.
• Anti-corrosion agents have been fully removed from the shaft ends.
If a common solvent such as acetone or a cleaning solvent is used, it must not be allowed to
wet the shaft sealing ring.
• The motor is designed for the ambient conditions and environmental influences on site
• The compartment in the machine is suitable for the cooling method employed for the electric
motor
The motor must be installed in such a way that the coolant lines can subsequently be
connected.
• The motor can be mounted and operated with the connection data and fastening features
provided.
• The mounting dimensions of the motor and the tolerance details are provided in the technical
documentation.
When mounting the flanges on the motor, make sure that the flange surface is in good, even
contact. The supports and bearing surfaces must be clean and undamaged. They must be
precisely aligned with the connecting shafts to prevent exposure of the bearings, shafts and
housing to damaging loads through misalignment. When tightening the flange mounting
screws (min. strength class 8.8), make sure that the flange connection is not distorted.
• No liquid can penetrate the upper bearing when installing vertically with the shaft end facing
upwards.
• The permitted radial forces according to the operating characteristics in the technical
documentation that accompanies the product are not exceeded (if necessary, contact
Baumüller for clarification).The motor manufacturer must always be contacted if axial forces
occur.
• The brake (optional) can be released once the operating voltage has been applied (audible
operating noise).
• The rotor rotates smoothly without a scraping sound.
On motors with a brake fitted, release the brake beforehand.
• The design of the motor and encoder cables complies with the details in the technical
documentation that accompanies the product.
• The output and input elements are secured.
• The complete cooling circuit is leak proof and fully functional
Leak test acc. to EN 50178:
The cooling system is to be checked for leaks before commissioning by pressure
testing with coolant (water). The test pressure must be twice the operating pressure
(minimum test pressure 1 bar). The coolant used does not have to be brought to
operating temperature for this purpose. Pressure must be maintained until all areas
have been tested for leaks (minimum test duration 10 minutes).
