1.1 NOTES
Prohibition against machining any part that is not designated by FANUC
Note the following points to use built-in spindle motors properly.
CAUTION
1 Never machine the stator. Also never machine any
pin hole for fixing the stator.
2 Do not machine parts of the rotor unless
designated by FANUC. For details, refer to "3.
ROTOR."
Liquid cooling
FANUC's built-in spindle motors are developed based on liquid
cooling. You will not obtain the rated output by air cooling. Use
liquid cooling system so that the rated output can be obtained.
Recommended coolant : ISO VG2 (e.g. Idemitsu Super Multi 2)
Be sure to use a coolant for which a manufacturing safety data sheet
(MSDS) is issued. When handing the coolant, refer to the data sheet.
When disposing of coolant, follow the related government and local
laws and rules.
Thermistor
Do not cool the thermistor locally. Over heat of motor may not be
detected. A thermistor is located in the coil in the power lead outlet of
the stator.
Easy maintenance
Consider some structure for easy
maintenance.
The structure that stator, rotor and sensor
can be disassembled by each unit (spindle
unit) is preferable.
Dry condition
A built-in spindle motor is an electric component. It may be damaged
by liquid like water and oil. Therefore keep away from these. And
also, keep away from the outer air. To supply air into a spindle, use
complete dry air, if not water will condense on and in the motor. Air
containing moisture may cause failure when it condenses in the
motor.
Record the manufacturing number
Write down and remember the serial number on the lead wire of stator,
and the manufacturing number on the side of rotor, so that you can
find the manufacturing number of the motor that is used in the
machine tool when maintenance.

  • Page 5B-65292EN/03 SAFETY PRECAUTIONS 1.2 WARNING WARNING - Be safely dressed when handling a motor. Wear safety shoes or gloves when handling a motor as you may get hurt on any edge or protrusion on it or electric shocks. - Use a crane or lift to move a motor from one place to another. Motors are heavy.
  • Page 6SAFETY PRECAUTIONS B-65292EN/03 WARNING - Do not supply the power to the motor while any terminal is exposed. A failure to observe this caution is very dangerous because you may get electric shocks if your body or any conductive stuff touches an exposed terminal. - Do not get close to a rotary secti
