1. Tips
It’s necessary to match the high speed spindle motor with
inverter. No allowing directly plugging the spindle motor to the power
supply. Otherwise, it will damage the high-speed spindle directly.
Before the inverter drives the spindle, all the parameters must be
set up correctly. Wrong settings will also damage the spindle motor.
2. JGL Pneumatic Tool Change Spindle Motor
JGL series is the high precise automatic tool change spindle motor,
drove by inverter, which can continuously adjust the spindle speed by
controlling the frequency. It has the characteristics of low noise, stable
and reliable operation, fast tool changing and high precision of repeated
tool change. It’s mainly used for high speed drilling, grinding and
engraving in machining centers. During the machining, the tool can be
changed automatically by the air cylinder on the spindle and CNC
controlling on the machine, which improves the machining efficiency.

2. 4、Installations
⑴、Operating ambient temperature range: -10℃~40℃
⑵、Before installation, manually rotate the spindle nose to check if
it’s smooth without any block.
⑶、check if the insulation resistance of stator is 200 MΩ or more.
⑷、Put the spindle into mount bracket without any loose.
⑸、For the water-cool spindle motor, cycled cooling liquid is needed
to go through the spindle during operation. The water amount is
0.5L/KW.min, minimum flow rate of the water is not less than 1.5 L/min;
A separate water tank is required for the cooling water with anti rust
inside. Precise machine tool require to keep the water homothermal at 22

±2℃. The inlet & outlet water tubing should be connected according to
the labels on the spindle. No leaking at the joint. Make sure the cooling
liquid flows smoothly.
⑹、Water prevention and shielding measures should be taken for the
power cables. It’s better no more than 200cm long of the distance
between the spindle motor and inverter. High frequency should be
prevented to avoid the interference on CNC machine controlling system.
⑺、Set up the parameters of inverter correctly. The inverter’s voltage
and frequency should accord with those of the spindle motor. (If the
inverter is not purchased from us, the rated frequency is usually made
50HZ. If directly running without any settings on the inverter, the spindle
will be burnt at once due to the high current). During the inverter setting,
its rated frequency (corner frequency), maximum frequency, maximum
voltage should correspond with those of the spindle graphs respectively.
Overload current is set 120% of the rated current. Overload protection
time is set 8s. Speed up & down is set 10~12s. Prolong the speed-up time
if the starting time exceeds the rated current.
⑻、Respectively connect U, V, W of the inverter with three thick
cables of the spindle. Another two thin wires are for thermistor. After
power on, inch the inverter. Observe if the spindle rotates in the same
direction as the arrow direction shown on the spindle. If not, stop the
spindle immediately, and then exchange any two of the three power
cables. In this way, the connection is surely correct. No allowing running
the spindle in the wrong direction.
⑼、
Check if the pressure of air supply is 0.6~0.8 mpa. And filter the
output air at the accuracy 25μm.
⑽、Before starting the spindle, ensure the valve of “air sealed” is
turned on normally at the pressure 0.1~0.15 mpa. From the beginning to

the end, no matter the spindle is working or the tool is changing, “air
sealed” should be activated all the time unless the whole CNC machine
stops, which is to avoid the pollution from cooling liquid or the cutting
chips.
⑾ 、 There is thermistor inside the spindle stator, with the model
103F3950，R25:10K 1% B: 3950K。It’s used to detect the temperature
inside the spindle.
2. 5、Air connection & steps of tool change
According to the labels at the back of spindle, connect “air inlet”,
“dust removal”, “air return” and “air sealed”. Adjust the pressure as
following:
air inlet: to release the tool holder, 0.6~0.7 mpa,
dust removal: to clean the dust off the internal of rotor, 0.4~0.5 mpa
air return: to make the air cylinder return to its initial position,
0.6~0.7 mpa
air sealed: to clean the dust & chips off the external of spindle
waterway , 0.1~0.2 mpa
To change the tool, please see the steps as following:
(1) Control the valve for tool released, pressurize “air inlet” for
3~5s. At this moment, clamp inside the spindle cone will open.
(2) Control the valve of “dust removal” and pressurize it at the
pressure 0.4~0.5 mpa.
(3) Insert the tool holder into spindle cone till the cone top.
(4) Turn off the valve of “air inlet” and “dust removal” at the
same time. Discharge the air inside the cylinder through exhaust. Now the

tool holder is installed.
(5) Turn on the valve of “air return” and pressurize it for 5s. Then
turn it off.
(6) Now that’s all for a whole step of tool changing.
(7) Turn on the valve of “air inlet” once again, the initially
installed tool holder will be released.
(8) A diagram of air connection:
2. 6、Sensor connection & operation
Without your specifications in advance, we offer PNP type of sensor
for the spindle. If NPN is needed, please specify in advance.

opened,the sensor for tool released will output signal of voltage. When
“air inlet” is turned off, and tool holder is in the right place of spindle, the
sensor for tool clamped will output signal of voltage. Only when the
sensor with too holder in place outputs voltage, the spindle can be started.
2. 7、Maintenance
⑴、Warranty period of bearings is 2500 hrs; for the other parts of the
spindle, it’s one year. However, maintenance has to be chargeable If users
ignore “air sealed”, which leads to the fluid or cutting chips entering the
bearing and then damaging the bearing / spindle.
⑵、
For new spindle or spindle with renewed bearings, to prolong its
lifetime, gradually speed it up from low rpm to high rpm. About an-hour
running for raising every 10000 rpm, till the maximum speed. It avoids
shortening the bearing lifetime if the spindle directly runs at high speed.
⑶、To stop the spindle, please cut off the power supply first, then
turn off the cooling water only when the spindle completely stops running.
In case of long-time deactivation, blow the cooling water out of the
spindle waterway with the compressed air.
⑷ 、 The spindle bearing lifetime will become longer by using the
tools with precise dynamic balancing.
⑸、After the spindle is deactivated or stored for six months, it can be
used only when the grease is replaced, otherwise, its lifetime will be
affected.

4. 2、V/F diagram
4. 3、Installations
⑴、Before unpacking the spindle, please check if the package is intact
without moisture.
⑵、Please check if the specifications of the motor accord with the
application requirement.
⑶、Carefully check if there is any damage or transformation during the
transportation, and if the fastener loosens or drops.
⑷、It’s permitted to install the motor spindle vertically or horizontally.
For self-cooling spindle, think about the heat dissipation during the
installation and use a radiator if necessary.
⑸、For water cool motor spindle, make sure the tubing joint is tight and
strong enough to avoid water leaking.
⑹、Generally, the spindle is fixed on its housing. Please manufacture
the holder according to the following image.。
⑺ 、 Before starting the spindle, manually feel if the spindle can rotate
smoothly without any blocking.。
⑻、For the spindle with power plug, its connection is like that: Below

3.5kw, its pin 1, 2, 3 are input terminal, which connect to U, V, W of the
frequency converter. Terminal 4 is grounded.
Above 4.0kw, 2, 3, 4 are input terminal while terminal 1 is grounded.
⑼ 、 The starting time of the spindle is usually 5~20 seconds. When
operation, please avoid prompt start as much as possible.
⑽、Correctly set up the frequency converter. (VFD) (If the VFD is not
purchased from our factory, usually the parameters are not suitable for the
motor spindle. So, it’s necessary to reset it) Make sure the rated frequency
(corner frequency), maximum frequency and its output voltage are in line
with those of the spindle.
⑾、After the VFD is set up well, start it without connection to the high
speed motor. Measure output of U, V, W with AC voltmeter to see if the
voltage goes up with the frequency rising, and then reach the set value.
Observe if the starting & stopping time is correct. Then connect it to the
spindle motor after it’s confirmed there is nothing abnormal.
⑿、Without the user’s extra statement, the spindle rotates clockwise by
seeing from the spindle back towards its front. No allowing running the
spindle in the opposite direction. Otherwise, the nut at the end of the
spindle will loosen and drop easily, and then cause danger.
⒀、For the motor spindle with dirt proof by air, the air that will enter the
spindle should be dehumidified and filtered to get it cleaned. The air
pressure is about 0.1~0.15mpa.
⒁、Intermittent or abnormal sound or vibration should not happen when
the spindle is running with & without loading. Temperature of the
bearings can not go up to 85℃.
⒂、If power supply deviates above 5%, continuous output of rated power
can not be guaranteed.
⒃ 、 No allowing overloading the motor spindle when it’s working
continuously.
