BL32 Ducted Fan 2150 Kv Brushless Motor Instructions

Thank you for purchasing the E-flite BL32 DF Brushless Motor. This motor is an ideal choice for products
such as E-flite’s Habu 32 DF and other similar sized ducted fan airplanes when using the purpose-built
Delta-V 32 80mm EDF (EFLDF32). The motor will provide great performance in 80mm diameter fan units
requiring a 28mm inrunner motor.

BL32 DF 2150Kv Motor Features:

• Purpose-built for the Delta-V 32 80mm EDF unit (EFLDF32)

• Ideal for 80mm EDF units

• Up to 1,400 continuous input watts or 1,665 maximum burst

• High-quality construction with ball bearings and hardened steel shaft

• Includes mounting hardware

• 6-pole design

* Data measured installed in Habu 32 DF using E-flite Delta-V 32 80mm EDF & 6S 5000mAh 30C Battery
(EFLB50006S30).

Static Data*

Static Thrust: 5.40 lb on 6S (21.9V)
RPM: 39,640 on 6S (21.9V)
Watts: 1,160 on 6S (21.9V)
Current: 53A on 6S (21.9V)
*Data measured in lab conditions using E-flite Delta-V 32 80mm EDF with bell mouth intake and tail pipe
measuring 159mm in length with 72.0mm exit diameter

* 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 may result in damage to the motor since excessive use of burst current may overheat the motor.

Battery Choices:

EFLB50006S30 5000mAh 6S 22.2V 30CLi-Po, 10AWG EC5

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 (EFLA249), 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.
