B-65272EN/04 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.
A motor is heavy. If you lift the motor by hand, you may get a
backache, or you may be seriously injured when you drop the motor.
A suitable crane or lift must be used to move the motor. (For the
weight of motors, refer to this manual.)
When moving a motor using a crane or lift, use a hanging bolt if the
motor has a corresponding tapped hole, or textile rope if it has no
tapped hole. If a motor is attached with a machine or any other heavy
stuff, do not use a hanging bolt to move the motor as the hanging bolt
and/or motor may get broken.
- Before starting to connect a motor to electric wires, make sure they are isolated
from an electric power source.
A failure to observe this caution is vary dangerous because you may
get electric shocks.
- Be sure to secure power wires.
If operation is performed with a terminal loose, the terminal block
may become abnormally hot, possibly causing a fire. Also, the
terminal may become disconnected, causing a ground fault or shortcircuit, and possibly giving you electric shocks. See the section in this
manual that gives the tightening torque for attaching power wires and
short-bars to the terminal block.
- Be sure to ground a motor frame.
To avoid electric shocks, be sure to connect the grounding terminal in
the terminal box to the grounding terminal of the machine.
- Do not ground a motor power wire terminal or short-circuit it to another power
wire terminal.
A failure to observe this caution may cause electric shocks or a
burned wiring.
* Some motors require a special connection such as a winding
switching. Refer to their respective motor specification manuals
for details.
- 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.
s-3
SAFETY PRECAUTIONS B-65272EN/04
WARNING
- Do not bring any dangerous stuff near a motor.
Motors are connected to a power line, and may get hot. If a flammable
is placed near a motor, it may be ignited, catch fire, or explode.
- Do not get close to a rotary section of a motor when it is rotating.
You may get your clothes or fingers caught in a rotary section, and
may be injured. Before starting a motor, ensure that there is no stuff
that can fly away (such as a key) on the motor.
- Do not touch a motor with a wet hand.
A failure to observe this caution is vary dangerous because you may
get electric shocks.
- Before touching a motor, shut off the power to it.
Even if a motor is not rotating, there may be a voltage across the
terminals of the motor.
Especially before touching a power supply connection, take sufficient
precautions.
Otherwise you may get electric shocks.
- Do not touch any terminal of a motor for a while (at least 5 minutes) after the
power to the motor is shut off.
High voltage remains across power line terminals of a motor for a
while after the power to the motor is shut off. So, do not touch any
terminal or connect it to any other equipment. Otherwise, you may get
electric shocks or the motor and/or equipment may get damaged.
- To drive a motor, use a specified amplifier and parameters.
An incorrect combination of a motor, amplifier, and parameters may
cause the motor to behave unexpectedly. This is dangerous, and the
motor may get damaged.
- Before driving a motor, be sure to secure it.
If a motor is drove without being secured, it may roll over during
acceleration or deceleration, injuring the user.
s-4
B-65272EN/04 SAFETY PRECAUTIONS
1.3 CAUTION
CAUTION
- Do not touch a motor when it is running or immediately after it stops.
A motor may get hot when it is running. Do not touch the motor
before it gets cool enough. Otherwise, you may get burned.
- Be careful not get your hair or cloths caught in a fan.
Be careful especially for a fan used to generate an inward air flow.
Be careful also for a fan even when the motor is stopped, because it
continues to rotate while the amplifier is turned on.
- Ensure that motors and related components are mounted securely.
If a motor or its component slips out of place or comes off when the
motor is running, it is very dangerous.
- FANUC motors are designed for use with machines. Do not use them for any other
purpose.
If a FANUC motor is used for an unintended purpose, it may cause an
unexpected symptom or trouble. If you want to use a motor for an
unintended purpose, previously consult with FANUC.
- Ensure that a base or frame on which a motor is mounted is strong enough.
Motors are heavy. If a base or frame on which a motor is mounted is
not strong enough, it is impossible to achieve the required precision.
- Be sure to connect motor cables correctly.
An incorrect connection of a cable cause abnormal heat generation,
equipment malfunction, or failure. Always use a cable with an
appropriate current carrying capacity (or thickness). For how to
connect cables to motors, refer to their
respective specification manuals.
- Ensure that motors are cooled if they are those that require forcible cooling.
If a motor that requires forcible cooling is not cooled normally, it may
cause a failure or trouble. For a fan-cooled motor, ensure that it is not
clogged or blocked with dust and dirt. For a liquid-cooled motor,
ensure that the amount of the liquid is appropriate and that the liquid
piping is not clogged. For both types, perform regular cleaning and
inspection.
- When attaching a component having inertia, such as a pulley, to a motor, ensure
that any imbalance between the motor and component is minimized.
If there is a large imbalance, the motor may vibrates abnormally,
resulting in the motor being broken.
s-5
SAFETY PRECAUTIONS B-65272EN/04
CAUTION
- Be sure to attach a key to a motor with a keyed shaft.
If a motor with a keyed shaft runs with no key attached, it may impair
torque transmission or cause imbalance, resulting in the motor being
broken.With the αi series, a shaft with no key is used as standard.
s-6
B-65272EN/04 SAFETY PRECAUTIONS
1.4 NOTE
NOTE
- Do not step or sit on a motor.
If you step or sit on a motor, it may get deformed or broken. Do not
put a motor on another unless they are in packages.
- When storing a motor, put it in a dry (non-condensing) place at room temperature
(0 to 40 °°°°C).
If a motor is stored in a humid or hot place, its components may get
damaged or deteriorated. In addition, keep a motor in such a position
that its shaft is held horizontal and its terminal box is at the top.
- Do not remove a nameplate from a motor.
If a nameplate comes off, be careful not to lose it. If the nameplate is
lost, the motor becomes unidentifiable, resulting in maintenance
becoming impossible. For a nameplate for a built-in spindle motor,
keep the nameplate with the spindle.
- Do not apply shocks to a motor or cause scratches to it.
If a motor is subjected to shocks or is scratched, its components may
be adversely affected, resulting in normal operation being impaired.
Be very careful when handling plastic portions, sensors, and windings,
because they are very liable to break. Especially, avoid lifting a motor
by pulling its plastic portion, winding, or power cable.
- Do not conduct dielectric strength or insulation test for a sensor.
Such a test can damage elements in the sensor.
- When testing the winding or insulation resistance of a motor, satisfy the
conditions stipulated in IEC34.
Testing a motor under a condition severer than those specified in
IEC34 may damage the motor.
- Do not disassemble a motor.
Disassembling a motor may cause a failure or trouble in it.
If disassembly is in need because of maintenance or repair, please
contact a service representative of FANUC.
- Do not modify a motor.
Do not modify a motor unless directed by FANUC. Modifying a
motor may cause a failure or trouble in it.
- Use a motor under an appropriate environmental condition.
Using a motor in an adverse environment may cause a failure or
trouble in it. Refer to their respective specification manuals for details
of the operating and environmental conditions for motors.
s-7
SAFETY PRECAUTIONS B-65272EN/04
NOTE
- Do not apply a commercial power source voltage directly to a motor.
Applying a commercial power source voltage directly to a motor may
result in its windings being burned. Be sure to use a specified
amplifier for supplying voltage to the motor.
- For a motor with a terminal box, make a conduit hole for the terminal box in a
specified position.
When making a conduit hole, be careful not to break or damage
unspecified portions. Refer to an applicable specification manual.
- Before using a motor, measure its winding and insulation resistances, and make
sure they are normal.
Especially for a motor that has been stored for a prolonged period of
time, conduct these checks. A motor may deteriorate depending on the
condition under which it is stored or the time during which it is stored.
For the winding resistances of motors, refer to their respective
specification manuals, or ask FANUC. For insulation resistances, see
the following table.
- To use a motor as long as possible, perform periodic maintenance and inspection
for it, and check its winding and insulation resistances.
Note that extremely severe inspections (such as dielectric strength
tests) of a motor may damage its windings. For the winding
resistances of motors, refer to their respective specification manuals,
or ask FANUC. For insulation resistances, see the following table.
MOTOR INSULATION RESISTANCE MEASUREMENT
Measure an insulation resistance between each winding and
motor frame using an insulation resistance meter (500 VDC).
Judge the measurements according to the following table.

α

1 GENERAL
As motors for driving the spindle of a CNC machine tool, the FANUC
AC Spindle Motor αi series has incorporated accumulated
technologies and employs the latest design and manufacturing
techniques to provide the features listed below.
Features
- The series provides a lineup of motors that satisfy various
spindle driving structures such as gear driving, belt driving, and
direct motor connection. So, the user can choose an optimal
motor that meets the spindle driving structure of the user.
- By employing winding switching, a wider rated output range
required for the spindle driving motor of a machine tool is
achieved. With the αi series, a high-speed winding is used to
remarkably increase the output level in the high-speed area, thus
reducing acceleration/deceleration time. With the αi
low-speed winding is used to increase the torque by a factor of
1.5.
- An up-to-date stator cooling method is employed for direct aircooling of the electromagnetic steel plate. So, a high power and
high torque are achieved with a compact size.
- By precision rotor aluminum casting and accurate rotor balance
correction, vibration grade V3 (option) is achieved even at high
speed.
- The user can select a motor fan exhaust direction: forward
direction or backward direction. An exhaust direction that
subjects the machine to less heat deformation can be selected.
With the αi series, the cooling air path is optimized to further
improve cooling performance.
- Two types of speed sensors built into the motor are available: Mi
sensor based on the A/B-phase signal and MZi sensor based on
the A/B-phase signal and one-rotation signal. The user can
choose between the two types according to the spindle
configuration and spindle function.
- This series employ waterproof and pressure-proof design
conforming to the international standard (IEC).
