DMA2 & DM1 Mounting & Maintenance Instructions
4.2
Indirect coupling
4.2.1. Flat or V Belts
Mount the motor on slide rails in order to adjust belt tension. The belt pulley has to be
fitted hard up the shoulder of the shaft. The pulley center line should be within the shaft
center line. Use correctly sized belts with a correct profile and in sufficient numbers to
drive without slip and undue tension. Align both pulleys accurately in such a way that the
center of both pulleys are in line. Multi V belt drives need to be matched sets.
A belt pulley, which is either too small or too wide, or too high, a tension on the belt may
damage the bearing or cause a shaft break. In case of doubt, consult the supplier.
4.2.2.
Spur Gear Drives
The motor and the driven machine have to be positioned in such a way that the two gears
mesh correctly. The motor should then be fixed with dowels.
4.3.
Shaft couplings and pulleys etc.
Remove the corrosion protection from the shaft extension and the coupling elements. The
coupling parts, belt pulleys and gear wheels need to be dynamically balanced and fit easily
on the shaft and to be provided with good fitting keyway.
In the factory the rotor has already been dynamically balanced including a half key in the
shaft.
The dimension and the tolerances of the shaft extension and the key are indicated on the
motor dimension sheet.
Assembling the coupling elements has to been done with great care. Careless handling
may damage the bearings, shaft or end shields.
Do not file or emery the shaft to achieve a fit!
hen fitting pulleys couplings or bearings, we recommend using heat to elements; therefore
the part to be mounted has to be heated till ± 80 degrees above the ambient
temperature.
A large washer and set screw can be useful for pushing on pulleys using the tapped hole in
the shaft. Only use proper tools for removing the above mentioned parts e.g. pulley
drawers.

ELECTRICAL CONNECTION
5.1.

General information

On delivery the motor will rotate clockwise looking at the drive when the phases L1, L2
and L3 are connected respectively to the connection terminals U1, U2 and U3.
Exchanging any two-phase lines can change the direction of rotation.
