Performance Data (Measured Using BL480 Motor)

Static Thrust: .9 lbs on 3S (11.1V)

1.8 lbs on 4S (14.8V)
RPM: 39,000 on 3S (11.1V)
49,000 on 4S (14.8V)
Watts: 255 on 3S (11.1V)
590 on 4S (14.8V)
Current: 25A on 3S (11.1V)
43A on 4S (14.8V)

* Maximum Operating Temperature: 220 degrees Fahrenheit
* Adequate cooling is required for all motor operation at maximum current levels.
* Maximum Burst Current duration is 15 seconds. Adequate time between maximum burst intervals is required for
proper cooling and to avoid overheating the motor.

* Maximum Burst Current rating is for full high power and limited motor run flights. Lack of proper throttle
management, especially on 4S operation may result in damage to the motor since excessive use of burst
current may overheat the motor.

There are many Li-Po battery brands on the market offering several choices for consumers. We recommend either
E-flite or Thunder Power batteries and list some possible choices for the BL480 DF Brushless Motor, depending on
the airplane application. Battery technology is constantly changing and manufacturers are improving and updating
older packs with new ones so the list above may generally be substituted for the packs they replaced.

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. Please be sure the timing is set
properly on your controller. This is a 6-pole motor.

2. The BL480 motor requires the PWM Switching Frequency to be set at 16 kHz. If the PWM Switching
Frequency in the speed control is not set to 16 kHz, the BL480 will not run properly on 4S batteries. The
default Switching Frequency setting in both the EFLA1040 40A Pro ESC and the EFLA1060 60A Pro ESC
(required for 4S power) is 8 kHz. This setting can be changed in Programming Menu 6 of either controller.
Without making this change the motor will fail to operate on 4S; while advancing the throttle, the motor will
turn off and spool down inconsistently and without warning.

3. When mounting the motor, be sure the correct length of screws (6mm) are used.

4. 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.

5. If you add connectors and or you no longer wish to use them, never cut the motor wires. Remove them b y
properly de-soldering them. Shortening the motor wires is considered an improper modificatio n of the motor
and may cause the motor to fail.

6. 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.

7. Proper cooling of the motor is very important during operation. New technology has brou ght 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.

8. 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.
