s-2
B-65342EN/01 SAFETY PRECAUTIONS

WARNING

WARNING
- Wear the appropriate protectors and clothes when you handle the 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.

- Keep the rotor away from the person who has medical machines, inplants, etc.
The rotor has strong magnet inside. So, keep the rotor away from the
person who wears medical machines, inplants, etc. The person who
wears medical machines or inplants must not handle the motor.

- Drive the motor with proper amplifier and parameters

BiS series should be driven by specified proper amplifier and
parameters. Incorrect combination of amplifier or parameter may
cause serious accident.

- Don’t drive BiS series without Sub module SM (SSM)

SSM is always necessary for BiS series. SSM protects person and
machine from dangerous high voltage in abnormal accident. Connect
the specified SSM without exceptions.

- Keep the rotor packed until assembly

The rotor is danger because of its strong magnetic force. So, keep the
rotor packed until the rotor assembly. When the rotor is left
temporarily for some preparations, the rotor should be wound by some
thick soft non-magnetic material, such as corrugated cardboard etc.,
with the thickness of more than 30mm. And rope off the rotor, call
attention that the rotor has strong magnetic force. to keep away from a
person to access the rotor.

- The taps on the end surface of stator jacket should be used only for lifting stator
alone
The taps on the end of the jacket are provided only for the assembling
and handling the stator itself.
Do not lift up the stator with another parts on by this tap. The strength
of the tap is not enough to lift the stator with additional weight.

- Use a crane or some supporting machine when you handle the motor
The motor parts are heavy. Use a crane or another equipment as
required.

- Be careful to the magnetic force on the surface of the rotor

The rotor has strong permanent magnets inside. There is 50N/cm2 of
magnetic force on the rotor surface. So, keep away magnetic materials
from the rotor, and keep the rotor away from magnetic materials.
When they crash with each other, be careful not to sandwich your
hand, etc.

s-3
SAFETY PRECAUTIONS B-65342EN/01

- The rotor rushes into the stator, when assembling rotor into spindle
When you insert the rotor in the spindle, the rotor will suddenly rush
into the stator bore by magnetic force. So, be careful enough not to
sandwich your hands, etc. Do not stand on an axial extension line of
the spindle.

- Do not touch the motor by a wet hand.

There might be an electric shock and is very danger.

- When you wire the power lead, confirm that a power supply is turned off.
There might be an electric shock and is very in danger.

- Inflammables or explosive substances must be kept away form the motor

The motor in driven is very hot. So, dangerous substances must be
kept away from the motor.

- Motor must be grounded

To avoid getting an electric shock, the stator core or the parts which
has good electrical connection to the stator core must be grounded.

- Do not short circuit the power line to the ground or short each other
To avoid getting an electric shock or damages of winding, do not short
the circuit.

- Each lines terminals should be connect firmly

If a line comes off the terminal, the line may short circuit, or get an
electric shock, etc., it is very danger.
If a clamping screw of a terminal is loose, the part runs hot and may
cause a fire. Connect each Lines and terminals firmly.

- Cover all the terminal with insulator

If a hand or conductor touches an exposed terminal, there may be a
danger of getting shocked.

- Keep away from rotating part when the motor is running

There is a danger that your clothing or fingers are rolled up or hit by a
rotating part.
Check the rotating part that there is no loose part on the rotating part
before running

- Turn off the power source when you touch the motor
Even if a motor does not run, there is the possibility that the voltage is
alive on terminals.
Especially, when you touch power lead, terminals, etc., be careful not
to get shocked.

s-4
B-65342EN/01 SAFETY PRECAUTIONS

- Do not touch the terminals, power leads, etc., without checking voltage
Even if the power line is turned off, the high voltage is still alive on
the power lines for a few minutes. So, do not touch those power line
parts without voltage check.

- When the motor is running, do not stay in the dangerous area of the rotating axis
The parts which on the rotating shaft may splash and hurt you.

- The design and assemble of a machine should conform to EN60204-1

For the safety design, the design and assemble of a machine should
meet EN60204-1.

s-5
SAFETY PRECAUTIONS B-65342EN/01

CAUTION

CAUTION
- A magnetic card, magnetic media, computer, etc. should be kept away from the
rotor
An electric or magnetic equipments, such as camera, cellular phone,
magnetic card, etc. might be broken by the leakage flux of the rotor.

- Do not touch the running motor and the motor just after a stop
The running motor is very hot. So, do not touch the motor until the
motor gets cold enough in order to avoid a burn.

- FANUC motor is designed only the usage for a machine tool. Do not use another
purpose
If a FANUC motor is used for unintended purpose, it may cause an
unexpected accident or trouble. Use a FANUC motor only with
machine tools.

- The base or frame on which the motor is to be mounted must have sufficient
stiffness
Insufficient stiffness or rigidity may cause many troubles. For
example, it generates rough surface in machining, harmful vibration,
abnormal sound, and shorten the life of bearings. It causes also the bad
machining precision of a machine tool itself.

- Install a motor without failure.

It is dangerous that a part of a motor or on the rotating part is removed
or scattered when motor is rotating..

- Connect motor cables correctly.

An incorrect connection of a cable may cause trouble. Use a cable
with thick enough for the current carrying capacity.

- Cool a motor with specified cooling condition.

Insufficient cooling may cause trouble. Keep a specified cooling
condition. Check that the flow rate of liquid is appropriate and the
liquid piping is not clogged. The periodic cleaning and inspection is
necessary. Build the system to stop the motor when the cooling unit is
in trouble.

- Take measures to leakage current.

The leakage current of the synchronous built-in spindle motor may
exceed the value specified in EN60335-1. Take appropriate measures
against leak current. For example, adopting a structure that prevents
the operator from contacting conductive parts near the motor during
power is alive.

- Connect the thermistor line to amplifier

For the thermal protection, connect the thermistor line to the amplifier.

s-6
B-65342EN/01 SAFETY PRECAUTIONS

- Do not drive BiS series without amplifier

Applying a power source voltage directly to a motor may burn its
windings. Use a specified amplifier to drive BiS series.

1.3 SUB MODULE SM

To drive BiS series, it is necessary to connect a Sub module

SM(SSM) between motor and amplifier for safety and machine
protection.
Synchronous motor has permanent magnets inside of the rotor. So, if
the motor runs freely by its inertia because of some power source
trouble, the motor turns itself into generator and the high voltage
comes back on power line terminal. In order to avoid this dangerous
state, SSM is necessary for the driving of synchronous motor. SSM
shorts the circuit of power line when an alarm is detected.

Order No. and dimensions are shown in this manual.

Also refer to the description manuals(*) of the latest version for the
detailed connection and specifications.
(*) SYNCHRONOUS SPINDLE MOTOR driven manual
A-63639-103 and SERVO AMPLIFIER αi series
DESCRIPTIONS (B-65282EN)

WARNING
1 To drive BiS series, be sure to connect SSM
between motor and amplifier for safety and
machine protection without exception.
2 Even if the motor is driven only in low speed, SSM
must be connected without exception for the safety
measures in case of incorrect operation or
unexpected accident. Never to drive the BiS series
without SSM.

CAUTION
During 2 minutes from the SSM operation, such
case as some spindle alarm or other emergency
stop, the reset command of alarm is ignored. This
is a standard function and not a trouble. While this
process, if some rotation command is active, the
spindle rotates suddenly after two minutes, so
please be careful. For more details, refer to the

2.1 INFORMATION AND INSTRUCTION

2.1.1 Safety Information

Do not machine to motor parts

Do not machine motor parts such as the stator, rotor, and ring by
yourself. Other wise, the necessary strength or accuracy cannot be
achieved, causing a malfunction.

Liquid cooling
BiS series are developed on condition of liquid cooling. The rated
output will not be obtained by another cooling e.g. air cooling.
Recommended coolant : ISO VG2(e.g. Idemitsu Super Multi2)
Select the coolant which has a manufacturing safety data sheet
(MSDS) . When handing the coolant, refer to the data sheet.
When disposing of coolant, follow the related government and local
laws and rules.

Design the spindle so that the pole position detecting function could execute
When driving a synchronous built-in spindle motor, it is indispensable
for controller to catch pole position of the rotor. Therefore when the
first driving after turning on amplifier, the pole position detecting
function is always executed, and pole position is set. To run this
function, the spindle should be able to rotate freely.
If speed increasing gear or brake is used, design the spindle so that
make the spindle free from these loads when the detecting function is
operating.
(*) ‘Free’ means that the force of constraint to spindle is almost only
bearing’s load.

Stator mold
The resin mold of the stator is applied to increase the heat rating.
There is no advantage for bad environment than no molded motor.
Therefore the protection class of the motor housing must be IP54 or
more.
(*) There are some chips, bubbles and cracks in mold resin. If the
protection class is IP54 or more, there is not bad influence in
performance. There is some visible internal wire in coil-end mold,
however it is not a problem in performance.

Thermistor
Do not cool the thermistor partially. If the thermistor partially cooled,
the over heat alarm of the stator may not be detected. A thermistor is
placed on the coil under the power lead outlet.

Design for easy maintenance

For easy maintenance, the structure of the spindle should be designed
to assemble easy, for example, a stator, rotor and sensor should be
disassembled by each unit.

- 18 -
B-65342EN/01 2.SPINDLE DESIGNING AND MOTOR MOUNTING

Dry condition
BiS series is an electric component. It may be damaged by liquid like
water and oil. Therefore keep away from them. If the air is supplied
into a spindle, take some structure not to catch condensed dew. Even
if the air is dried, dew condensation may occur by the effect of the
adiabatic expansion. Therefore be care enough. If dew condensation
happens in motor, trouble may occur.

Keep 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 when the maintenance.

Check resistance and insulation

Before assembling a spindle, check the resistance and insulation of
winding. And also check them on periodically maintenance.

WARNING
Shutdown the power supply and disconnect the
leads which are connected to the amplifier before
measuring to prevent an electric shock. In
measuring, insulate the open terminals so that not
to touch.

Winding resistance
Measure the winding resistance by milli-ohm meter according to the
following list. Insulate the terminals that are not used while
measuring.

U-V, V-W, W-U [mΩ]

2.2 SHRINKING THE ROTOR

2.2.1 Safety Information

• The outline flow for process is shown below.

Shaft

Rotor, Side ring

Shrink fit a rotor

Finish machining

Balancing spindle

Assemble into the spindle

• The way to fix a rotor on the spindle must be shrink fitting.

• Rotor and side rings are finished machining before shipment. Do

not machine rotor and rings.

• "Finish machining" in above means that of bearing part or the

part except motor.
In the machining, cover the rotor with some flexible sheet so that
the rotor not to catch cutting chips on its surface. Furthermore,
cover the rotor in industrial wrap so that the rotor doesn’t get wet
with cutting fluid.

• When shrink fitting a rotor, the actual temperature of the rotor

must be measured directly so that the temperature never to
exceed 150°C. If rotor temperature exceeds 150°C, internal
magnet may be damaged. If you use an electric oven, measure
the distribution of temperature inside of the oven. The rotor is
never exposed to a hot wind directly. Never use the induction
heater.

• Shaft should be cooled to 0°C or less.

• When the rotor is left temporarily for some preparations, the

rotor should be wound by some thick soft non-magnetic material,
such as corrugated cardboard etc., with the thickness of more
than 30mm. And rope off the rotor, call attention that the rotor
has strong magnetic force. to keep away from a person to access
the rotor. Wrap is to prevent the rotor from caching metal chips
on its surface, and soft material or corrugated cardboards is the
buffer material for the safely.

2.SPINDLE DESIGNING AND MOTOR MOUNTING B-65342EN/01

• All the rotor are checked its unbalance in production process. So

normally, it is unnecessary to balance for the rotor after
shrinkage fit, only to balance the whole main shaft. If user needs
more precise balancing of the rotor, the taps on the side ring’s
can be used. The allowable mass is following table. Do not
exceed these value.

Allowable mass [g]

Total mass per one ring For one tap
B132Lx 6g 2g
B160Lx 8g 2g

• The taps on the side ring is only for the balancing the rotor.
Never use it for the whole balancing of the main shaft.

• Never machine rotor and side ring.

• We recommend to mount the rotor to spindle directly without

sleeve. If customer uses rotor sleeve, the interference should be
taken enough so that the rotor not to slip.

WARNING
Synchronous spindle motor, control soft must
always catch pole position. If it is missed by some
causes, it will be possible to cause uncontrollable
condition. This is very danger.
Therefore, the fixing torque must be taken enough
so that not to slip the rotor.
If the possibility of the slip is happen, for example a
crushing spindle, the spindle must not be restarted
without running pole position detecting function.

• Electro static charge of the spindle :

There is some possibility that electro static voltage is charged on
the spindle. It may be caused by bearing lubricating structure or
cutting condition, and depends on the spindle structure.
Particularly if a ceramic bearing is used, it is obvious. We
recommend to take some structure that the electric potential
voltage becomes equal between the grounded stator core and the
spindle. If no measures are taken, electric discharge will happen
between rotor and stator, or spindle and sensor, and it will be the
cause of some trouble.
