The reason why spindle motor have Condensed water
When the temperature in the spindle is significantly different from the ambient temperature，Humid air entering and inside the spindle .
Since with more and more humid air accumulation in the inside spindle motor ,it finally form to small waterdrop.
The harm of Condensed water inside spindle motor
If the Condensed water enter into stator, it may caused Coil burnout.
If the Condensed wanter enter into bearing, it may dilution the grease oil and destory the bearing
How to prevent Condensed water from spindle motor
A. In the case of with air conditioning
DECI spindle motor service team advise to Set the chiller temperature to ± 2°C degrees from the ambient temperature, or Turn on environment mode（Room temperature synchronization）.
A. In the case of without air conditioning
DECI spindle motor service team advise to Set the chiller temperature to 25°C~25°C degrees.
