(2) Location
Use the motor under the following conditions.
●
Indoors
●
Free from corrosive and/or explosive gases or liquids
●
Ambient temperature: O to
Clean and dry
●
Accessible for inspection and cleaning
If the AC servomotor is subject to excessive water or oil droplets, protect motor with a cover.
The motor can withstand a small amount of splashed water or oil.
(3) Environmental Conditions
Ambient Temperature: O to
Storage Temperature: –20 to
●
Humidity: 20% to 80% RH (non-condensing)
(4) Load Coupling
True alignment of motor and driven machine is essential to prevent vibration, reduced bearing
and coupling life, or shaft and bearing failures.
Use flexible coupling with direct drive. The alignment should be made in accordance
with Fig. A8. 2

the shafts.
the gap between the coupling faces at four equidistant points around
the coupling rim with thickness gage The maximum variation between any two
readings should not exceed O.
(5) Allowable Bearing Load
Avoid both and radial loads to the motor shaft. If unavoidable, never exceed the values
in Tables A4.
