this Brushless Motor. Read this and all the associated component Operation Manuals carefully before use. Always
keep this Operation Manual in a place where a user can referred to for reference at any time.
■Read these warnings and cautions carefully and only use in the manner intended.
■These warnings and cautions are intended to avoid potential hazards that could result in personal injury to the
operator or damage to the device. These are classied as follows in accordance with the seriousness of the risk.
Class Degree of Risk
WARNING A safety hazard could result in bodily injury or damage to the
device if the safety instructions are not properly followed.
CAUTION A hazard that could result in light or moderate bodily injury or
damage to the device if the safety instructions are not followed.
CAUTIONS FOR HANDLING AND OPERATION
1.
①This Brushless Motor is not a hand tool. It is designed to be used on CNC machines or special
purpose machines.
②Do not touch the cutting tool while it is running. It is very dangerous.
③Wear safety glasses, dust mask, and use a protective cover around the Brushless Motor whenever
the Brushless Motor is rotating.
④Never connect, disconnect or touch the Power Cord Plug or Motor Cord Plug with wet hands. This
may cause an electric shock.
⑤Never operate or handle the Brushless Motor and spindle until you have thoroughly read the
Operation Manuals and safe operation has been conrmed.
1) To prevent injuries / damages, check the Brushless Motor, spindle and cutting tool for proper
installation, before operating the Brushless Motor and spindle.
2) Before disconnecting the Brushless Motor and spindle, always turn the control power off and
turn the compressed air supply to the CONTROLLER off. Then it is safe to remove the Brushless
Motor and spindle.
⑥When installing a Brushless Motor to a xed base, make sure the xed base is grounded in order
to avoid the risk of an electric shock.
WARNING
①Do not drop or hit this Brushless Motor, as shock can damage to the internal components.
②Select suitable products or tools for all applications. Do not exceed the capabilities of the
Brushless Motor or tools.
③Do not stop the supply cooling air for Brushless Motor during operation of the machine.
Removing the air pressure from the Brushless Motor causes a loss of purging, allowing the
Brushless Motor to ingest coolant. This will cause damage to the Brushless Motor.
④Carefully direct coolant spray to the tool. Do not spray directly on the Brushless Motor body. If
large amount spray directly on the Brushless Motor, it may cause excess load of the Brushless
Motor rotation with loss of durability to the Brushless Motor.
⑤Stop working immediately when abnormal rotation or unusual vibration are observed. Immediately,
please check the content of section " 11. TROUBLESHOOTING ".
⑥Always check if the connection hose and supply air hose for damaged before and after operating.
⑦After installation, repair, initial operation, or long periods of non operation, please carry out break
-in as follow. Start rotating slowly and over a short period of 15 - 20 minutes, increase speed
gradually until allowable maximum speed.
⑧Do not disassemble, modify or attempt to repair this Brushless Motor. Additional damage will
occur to the internal components. Service must be performed by NSK NAKANISHI or an authorized
service center.
⑨When using this Brushless Motor for mass production, please consider the purchase of an
additional Brushless Motor to be used as a back-up in case of emergency.
⑩Securely connect the compressor supply connection hose to the Air Line Kit, and connect the air
hose to the Air Line Kit, CONTROLLER and the Brushless Motor to avoid accidental disconnection
during use.

FEATURES5.
①The Brushless Motor housing is made from precision ground, hardened, stainless steel (SUS) with an outside
diameter of ȭ30mm.
②Excellent durability and high reliability are obtained by using a high-speed Brushless Motor, which eliminates
the need for brush replacement and frequent maintenance.
③The maximum output is 350W.
④Air-cooling system with a small volume of air (30ℓ/ min) is used to prevent heat buildup and allows long
continuous operation.

CONNECTION OF THE MOTOR TO THE SPINDLE10.
Make sure your hands and all interlocking parts of the spindle and Brushless Motor are clean before
connecting the Brushless Motor to the spindle. This is critical in preventing contaminants from
entering the Brushless Motor or spindle.
CAUTION
Align the thread on the front end of the Brushless Motor and the rear of the spindle, and turn the spindle clockwise.
If the drive shaft of the Brushless Motor does not engage properly to the drive dog on the spindle, it may only
turn approximately two threads before stopping. DO NOT FORCE THEM TOGETHER. Loosen the spindle from
the Brushless Motor, rotate the spindle shaft by hand then re-try. The drive shaft and the drive dog must be fully
engaged. When fully engaged, secure the Brushless Motor and spindle using the provided 27mm wrench (Fig. 8).
