Under any exception must be the free flow of air to the cooling fan to avoid the
overheating of the motor. This has to be consider also when motor is mounting in small
rooms with limited space. The ambient temperature must not exceed 40 degrees
centigrade, if more has to be consider with the supplier.

COUPLING
4.1
Direct coupling
The motor and the driven machine must be mounted in one line to avoid tension on the
shaft. Bad alignment can be a major source of noise and vibrations.
We do not recommend using solid couplings.
4.2 Indirect coupling
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.
