Aligning the machine to the driven machine (high-speed version)
In the case of motors with high-speed design, the vertical positioning is achieved using the
adjustment screws of the machine bearings. They can also be used to compensate for any
settling that may take place. Please see the manufacturer's data sheet for information on
tightening torque values.

Aligning the machine to the driven machine and attaching it to it (IM B5)
The standard flange is provided with a centering. The choice of fit for the mating flange on the
driven machine is the system manufacturer's or the plant operator's responsibility.
Note
If the machine is not fitted with a standard flange, align the machine to suit the driven
machine.
Procedure
The machine axis must be horizontal when it is lifted and the flange must be parallel to the
mating flange, so as to avoid seizing and stressing. Otherwise damage to the centering will
result.
1. Grease the centering flange with assembly paste to make the process easier.
2. Screw three studs into tapped holes spaced about 120° apart around the driven machine
3. Position the machine so that its axis is aligned with that of the driven machine, but not yet
4. If necessary, rotate the machine into the right position so that the clearance holes in the
5. Move the machine fully up against the mating flange so that it is fully in contact.
6. Fix the machine using the flange fixing bolts, finishing by replacing the studs.
