Thank you for purchasing the KEYENCE Sensor-Controlled Brushless Motor.
This motor provides the best performance when used in combination with the KEYENCE
brushless ESC "TACHYON". To obtain 100% performance of this product, be sure to readthis instruction manual. After reading this manual, keep it carefully.

REFERENCE GEAR RATIO
Select an appropriate gear ratio based on the reference values listed below. The following values
are only for your reference. The optimum gear ratio varies depending on the ESC performance,machine settings and characteristics of the traveling course. Determine the optimum gear ratio byobserving heating-up condition of the ESC and the motor.

FEATURES OF LUXON[Stylish next-generation design whenmounted]
The machined aluminum body has a dynamic
segmented design. Along with a mirrored
finish, the LUXON combines deep lines andlaser markings to give a powerful sophisticatedlook.

[Rotor with excellent heat resistance]

A permanent magnet is remarkably affected bytemperature change. When a certain
temperature is exceeded, a magnet will losemagnetic force, and magnetic force cannot berecovered even if the magnet is restored to theoriginal temperature.
To prevent loss of magnetic force due to atemperature rise, LUXON uses a sintered rotor
equipped with a neodymium magnet thatprovides excellent heat resistance.

[Cogging torque reduction]
Cogging torque is the magnetic attraction
force generated when a rotor rotates in motor
power OFF status. In actual use, cogging torquecauses irregular torque and vibration. It is adisturbance factor in sensor control. Therefore,
higher-precision motor control is enabled byminimizing cogging torque. Through cogging
torque reduction, LUXON enables direct andsmooth acceleration, from a low speed to ahigh speed.

* LUXON is a motor dedicated to sensor-controlled
brushless ESC. It is not applicable to sensorless ESC.

To prevent accident and fault:
The soldering of each part must be conducted within 5 seconds.

CAUTIONTo prevent accident and fault:
Make sure that the cables are properly connected. Do not connect the power supply
with reverse polarities. Be sure to insulate cable connection terminals. If theconnection terminals are short-circuited, it may result in damage to this product.

•About modification

To prevent smoke, fire and burns:
Never attempt to solder the circuit board and electronic components in the motor.

ESC “TACHYON”•Sensor cord
The sensor cord transmits a position signal of Hall element to a speed controller (hereinafter,referred to as ESC). Since the ESC and the motor use the same type of connector, there is nolimitation in cord inserting direction. However, when inserting the cord, match the cord with theconnector shape. If the sensor cord is not connected, the ESC initial setup cannot be performed.
(During travel, keep the sensor cord connected to the ESC.)
Connect the sensor cord securely, because a contact failure causes malfunction and damage toequipment. Modification of the sensor cord causes a failure of the motor. Never attempt to modify
the sensor cord.

•Motor cables (A, B, C)•Handling precautions
DANGER

To prevent smoke, fire and burns:
During use of this product (when a power supply is connected to the motor, or
when the power switch is ON), keep watching the motor. If an abnormal condition
occurs, it may result in fire or other accident.

CAUTIONTo prevent accident and fault:
Do not install this product in a place where water, oil, fuel or other conductive
liquids are present. Electronic components are vulnerable to minerals contained insuch liquids. If the product becomes wet with such liquids, immediately stop
operation, and dry it.

CAUTIONTo prevent accident and fault:
Be sure not to use the motor in fully-throttled condition, if the motor is notincorporated in a chassis drive unit. Running the motor at a high speed under noload causes damage to the motor.

CAUTIONTo prevent accident and fault:
If an improper gear ratio is selected, it results in motor overload, causing the motor
to be damaged by abnormal heating. Select an appropriate gear ratio carefully.

The motor cables are used to apply a voltage to the motor coil at appropriate timing, according to
the signal transmitted to the ESC via the sensor cord.
To connect the LUXON to the KEYENCE ESC “TACHYON”, soldering work is not required. A cablewith a connector plug is attached to the LUXON in advance.
WARNING To connect the LUXON to the ESC, be sure to connect the cables with the “A”, “B” and“C” symbols matched with each other. If a cable with a different symbol is connected,motor rotation control is disabled. Furthermore, a large current may flow through theESC and the motor, resulting in damage and burnout of the equipment. Unlike thesensorless type brushless motor, the LUXON cannot change the rotating direction even if
the cable connections are exchanged. Change the rotating direction* with the ESC, asrequired.
* To change the motor rotating direction, a rotating direction change function isrequired for the ESC. (TACHYON provides this function).

WARNING To replace the motor cable, use a soldering iron which provides a large soldering tip areaand high output (approx. 70 W), and quickly conduct the soldering work. If a solderingiron’s output is low, solder is hard to melt, disabling secure connections of the cables.
This may result in cable disconnection or contact failure when vibration is applied to thecable. If heat application time is excessively long, it causes damage to the internal parts.
(Use thorough caution so that the terminals will not be short-circuited by solder.)WARNING To fasten the motor to the motor mount, be sure to use screws with up to 8 mm length.
