Motor Mounting - WEG W22 Premium E3 Manual De Instalación, Operación Y Mantenimiento

The metallic and concrete bases may be fitted with sliding system. These types of foundations are generally
used where the power transmission is achieved by belts and pulleys. This power transmission system is easier
to assemble/disassemble and allows the belt tension adjustment. Other important aspect of this foundation
type is the location of the base locking screws that must be diagonally opposite. The rail nearest the drive
pulley is placed in such a way that the positioning bolt is between the motor and the driven machine. The other
rail must be placed with the bolt on the opposite side (diagonally opposite), as shown in Figure 6.4 .
To facilitate assembly, the bases may have the following features:
shoulders and/or recesses;
g
anchor bolts with loose plates;
g
bolts cast in the concrete;
g
leveling screws;
g
positioning screws;
g
steel & cast iron blocks, plates with flat surfaces.
g
After completing the installation, it is recommended that all exposed machined surfaces are coated with
suitable rust inhibitor.
