Operating Instructions:
1. This brushless motor requires the use of a sensorless brushless speed control. Failure to use the
correct speed control may result in damage to the motor and/or speed control.
2. When mounting the motor, be sure the correct length of screws (5mm) are used so damage to the
inside of the motor will not occur. The use of long screws will damage the motor.
3. You may connect the three motor wires directly to the controller with solder or use connectors such
as gold plated brushless bullet connectors (EFLA241), which will also need to be soldered properly
to your wires. The three motor wires can be connected in any order to the three output wires or
output port on a sensorless brushless speed control. Be sure to use heat shrink tubing to properly
insulate the wires so the wires will not short. Shorting may damage the motor and speed control.
4. If you add connectors and or you no longer wish to use them, never cut the motor wires. Remove
them by properly de-soldering them. Shortening the motor wires is considered an improper
modification of the motor and may cause the motor to fail.
5. When you connect the motor to the esc, check the rotation direction of the motor. If you find the
rotation is reversed, switching any two motor wires will reverse the direction so the motor rotates
properly.
6. Proper cooling of the motor is very important during operation. New technology has brought much
higher capacity batteries with higher discharge rates, which can cause extreme motor temperatures
during operation. It is the responsibility of the user to monitor the temperature and prevent
overheating. Overheating of the motor is not covered under any warranty.
7. You can install the rotor/propeller on the motor shaft after you have confirmed proper rotation
direction. Also consult the instruction included with your sensorless electronic speed control for
proper adjustments and timing.
8. Once the battery is connected to the motor, please use extreme caution. Stay clear of the
propeller/ducted fan rotor during operation. Spinning propellers/rotors are very dangerous as the
motors produce high amounts of torque.
9. Never disassemble the motor. This will void any warranty.
Motor Safety Precautions:
The motor will be used in an EDF unit that contains a rotating part so use extreme caution. Please
read the warning information included with your fan unit / propellers for safety information related to the
operation of motors with propellers. Failure to comply with these warnings and/or improper use of propellers
or EDF units may result in serious injury.
