AM - 26 Asynchronous Motors Ver. 0002
AM.9.3 AMBIENT CONDITIONS
Before mounting it onto the machine, the anti-rust paint should be removed from the rotor
shaft and the flange.
The environmental conditions recommended for the motor are the ones indicated in the
general characteristics bearing in mind that:
· It must be located in a clean and dry place.
· Easily accessible for inspection, cleaning and maintenance.
· Free of corrosive ambient and explosive gasses or fluids.
· If the motor is going to be exposed to oil splashes, it should be cover with a guard.
When installing it in difficult areas due to dust, water, too much humidity, vapor, smokes, oil,
solvents, etc. a motor meeting a higher sealing standard may be ordered.
None of the motors described in this manual can be installed in places with any risk of
explosion.
AM.10 COUPLING
The circular motion of the motor can be transmitted to the machine through direct coupling or
by using pulleys or gear boxes.
AM.10.1 DIRECT COUPLING
Use a joint which does not transmit axial loads to the roller bearings and does not compensate
for alignment errors between the transmission shafts. In the case of direct coupling (linked
shafts) be extra careful in order to guarantee the alignment between the motor shaft and the
pulled axis and between the coupling flanges. Any vibration or irregular rotation will indicate
poor alignment which will result in poor performance and shorter life-span of the bearings.
AM.10.2 COUPLING THROUGH TRANSMISSION PULLEYS
Install the motor with shaft perfectly parallel and aligned with the pulley shaft in order to avoid
axial loads on the supports. The tension of the pulleys must be enough to avoid slippage when
the motor is working at full load, but it must never exceed the maximum load described in this
manual. Too much tension on the pulleys may wear out the bearings faster and even break
the shafts.
Regarding the peripheral speed of the pulleys, transmitted power, diameter ratios of the
pulleys, etc. Refer to the technical data supplied by the manufacturer. Always use balanced
pulleys.
