Horizontal types of construction with mounting feet

1. Refer to any instructions for aligning the driven machine and those of the coupling
2. Align the motors with coupling output to the driven machine in such a manner that the
3. For the vertical positioning (x→0) place thin shims under the motor feet. The number of
4. When positioning the motor, ensure that a uniform axial gap (y→0) is maintained around
5. Fix the motor to the foundation. The choice of fixing elements depends on the foundation
5.5.2.3

Horizontal types of construction with flange

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.
If the motor is not fitted with a standard flange, align the motor to suit the driven machine.
Procedure
The motor 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.
1. Grease the centering flange with assembly paste to make the process easier.
2. Screw three studs evenly apart into tapped holes around the driven machine flange. The
3. Position the motor so that its axis is aligned with that of the driven machine, but not yet
4. Move the motor fully up against the mating flange so that it is fully in contact.
5. Fix the motor using the flange fixing bolts, finishing by replacing the studs.
