Fastening using IM B5/B14 flanges:
a) Connect and fastened the counter-flange: For correct fastening, use bolts with an appropriate diameter
in accordance with the dimensions of the flange as per the EN 60072 standard.
b) Make sure of the perpendicularity of the machine shaft and the counter-flange plane: Perpendicularity
errors must be below 0.05 mm.
c) Make sure that the counter-flange is appropriate: In accordance with section b) of the IM B3 assembly.
NB
Application of additional loads on the flange
The motor flange is dimensioned only to support its own weight. If there are additional loads, the flange may not
be sufficiently heavy duty and, therefore, faults may occur that affect the motor and the machine to which it is
coupled.
5.1.3
Machine coupling
The motor must be coupled to the machine very carefully since it is fundamental in order to ensure the correct
service life of the motor.
Before mounting the coupling, remove the plastic blue protection grille and clean the surface well.
PRECAUTION
Damages to the motor bearings
Prevent solvent from entering the interior of the bearings since they could be damaged.
If the motor works with a direct drive (coupled directly to the load), the appropriate coupling must be used to
compensate the alignment errors and radial forces that are applied. Please check with VASCAT S.A. in case of
doubt.
In any case, make sure that the alignment between the motor shaft and that of the machine corresponds to the
coupling between both parts.
PRECAUTION
Damages to the shaft and bearings
Excessive misalignment can cause overloads on the bearings and break the shaft or cause the bearings to seize
up through fatigue. The customer is responsible for ensuring the correct alignment of both shafts.
VASCAT motor rotors are dynamically balanced using a half-key on the end of the shaft (in accordance with the
60034-14 standard). To ensure the correct balance of the entire transmission unit, all the parts of the
transmission system must also be balanced (pulley, coupling, etc.).
The installation of the coupling or the transmission element must be made gently without knocking, previously
heating the pulley or using an appropriate tool (please see Figure 8).
