Mounting the motor

In order to ensure smooth, vibration-free motor operation, a stable foundation design is required, the motor must be
precisely aligned, and the components that are to be mounted on the shaft extension must be correctly balanced.
The following mounting instructions must be carefully observed:
● For high-speed machines, the complete unit should be dynamically balanced after couplings or belt pulleys have been
mounted.
● Use suitable equipment when mounting drive elements. Use the thread at the shaft extension.
● Do not apply any shocks or axial pressure to the shaft extension.
● Especially for high-speed motors with flange mounting, it is important that the mounting is stiff in order to locate any
natural frequency as high as possible so that it remains above the maximum rotational frequency.
● Thin sheets (shims) can be placed under the motor mounting feet to align the motor and to avoid mechanically stressing
the motor. The number of shims used should be kept to a minimum.
● In order to securely mount the motors and reliably and safely transfer the drive torque, bolts with strength class 8.8
according to ISO 898-1 should be used.
Note
All flange-mounted motors must have a stable motor suspension assembly and for high field weakening speeds must be
supported using the appropriate feet at the bearing end shield. For more information on foot/flange mounting, see Section
"Mounting orientation and outline dimensions (Page 73)".
Support using feet at the bearing end shield is not required if the following conditions are maintained:
For flange-mounted motors, there is a stable motor suspension design.
•
The permissible vibration values according to DIN ISO 10816 are maintained.
•
The maximum speed is limited (see Section "SIMOTICS M-1PH1 main motors (Page 396)").
•
Motors that are mounted, as a result of their type of construction, to the wall using the motor feet, must be fixed in place
through the use of an adequately dimensioned positive form fit (for example, studs or mounting rails).
When commissioning the motors, it must be ensured that the permissible vibration values according to DIN ISO 10816 are
maintained.
Note
Using the eyebolts
Lift the 1PH1 motor only at the eyebolts.
Note
Mount the motor so that the cooling air can enter and be discharged without any restrictions.
