NOTICE
Damage to the motor due to runout on the shaft extension
Runout and thrust on the shaft extension of the motor can damage the motor.
•
Mount the motor without runout and thrust on the shaft extension.
Note
Note the technical data on the rating plate on the motor frame.
•
Comply with the data on the rating plate, warnings, and notices on the motor.
•
Check the permissible ambient conditions (e.g. temperatures, installation altitude) at the
installation location.
•
Thoroughly clean the shaft extension of corrosion protection. Use commercially available
solvents.
•
Ensure sufficient dissipation of heat. See Chapter "Cooling (Page 40)"
•
If the motor is installed vertically with the end of the shaft facing up, ensure that no liquid
can enter the upper bearing.
•
Ensure that the flange is in even contact with the mounting surface.
•
Use the hexagon socket-head screws, property class at least 8.8.
•
When tightening the fastening bolts avoid any uneven stressing.
•
Observe the tightening torques of the fastening bolts of the motor flange. See table
"Tightening torques for fastening bolts".
Tightening torques for fastening bolts
The general tolerance for the tightening torque is 10%. The tightening torque is based on a
friction coefficient of μ
= 0.14.
