WARNING
the safety instructions are not properly followed.
A hazard that could result in light or moderate bodily injury or damage
CAUTION
to the device if the safety instructions are not followed
WARNING
① This brushless motor is not a hand tool. It is designed to be used on CNC machines or special
purpose machines.
② Do not touch the cutting tool while it is running. It is very dangerous.
③ Wear safety glasses, dust mask and use a protective cover around the spindle whenever the
spindle is rotating.
④ Never connect, disconnect or touch the Connector and Motor Cord Plug with wet hands. This
may cause an electric shock.
⑤ Never operate or handle the brushless motor until you have thoroughly read the Operation
Manuals and safe operation has been confirmed.
1) To prevent injuries / damages, check the spindle and cutting tool for proper installation,
before operating the brushless motor.
2) Before disconnecting the brushless motor, 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.
⑥ When installing a brushless motor to a fixed base, make sure the fixed base is grounded in
order to avoid the risk of an electric shock.
CAUTION
① Do not drop or hit this brushless motor, as shock can damage to the internal components.
② Select suitable products or tools for all applications. Do not exceed the capabilities of the
spindle or tools.
③ Carefully direct coolant spray to the tool. Do not spray directly on the brushless motor body.
④ Stop working immediately when abnormal rotation or unusual vibration are observed.
Afterwards, please check the content of section 7 "TROUBLESHOOTING".
⑤ After 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 time, increase speed
gradually until allowable maximum speed.
⑥ Do 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.
⑦ When using this brushless motor for mass production, please purchase the another brushless
motor as a spare in case of an emergency.

Degree of Risk
2 . FEATURES
① The Brushless Motor housing is made from precision ground, hardened, stainless steel (SUS) with an outside
diameter of 40 mm.
② Excellent durability and high reliability are obtained by using a high-speed brushless motor, which eliminates
the need for brush replacement and frequent maintenance.
③ The maximum output is 1200W.
④ A quick disconnect cord is available for easy brushless motor removal.
⑤ Air-cooling system with a small volume of air (100 ℓ / min) is used to prevent heat buildup and allows long
continuous operation.
