Hints and TipsImportant

Warning

When powered on, the motors and propellers will rotate very quickly and can cause serious damage or injuries if used improperly. Always maintain caution and make safety your top priority.

The E7000 generates powerful thrust. Be sure to operate it with caution to avoid potential safety risks. DO NOT use the E7000 if you are not an experienced user or you are under the age of 18.

1. The maximum allowable voltage of the E7000 is 52.2 V. Operate with care.

2. Always fly your aircraft in areas free of people, animals, power lines, and other obstacles.

3. DO NOT approach or touch the motors or propellers when the unit is powered on.

4. Before takeoff, ensure that the propellers and motors are installed correctly and the propellers are unfolded.

5. Ensure that all parts of the aircraft are in good condition. DO NOT

y with worn or damaged parts.

6. Check the connection of the 3-phase cable between the ESC

and motor before each ight. Ensure that the insulating tape is rmly attached and replace whenever required.

7. Ensure that all parts are firmly in place and all screws are

tight before each ight.

8. Only use compatible, authorized DJI parts.

Introduction

The E7000 Tuned Propulsion System is designed for multirotor aircraft with a payload of 6 to 8 kg/rotor. The system can be washed, making it ideal for industrial applications and aerial imaging in demanding environments, especially agriculture. The overall solution of a modular single rotor enhances convenience

for assembly and conguration. A 40mm diameter carbon ber

tube is included in the package, while providing a wide range of tube length to choose from.

The M12 motor is equipped with a weatherproof sealant for the bearing system and a coating for the motor's stator, preventing rust and corrosion. Reinforced blades and a perfected aerodynamic design minimize rotational inertia on the foldable 33-inch Z-Blade propellers to equip large platforms with sharp response.

The 12100 ESC uses FOC (Field-Oriented Control) algorithms to allow for more motor responsiveness and precision control. Additional protection functions extend the life of the ESC. When

used with the DJI N3, A3, N3-AG or A3-AG ight controllers, the ESC data cable handles communication with the ight controller

and also acts as a backup throttle signal transmission cable for

increased reliability and a safer ight.

1. Parts

2. Flight Controller Settings

The E7000 ESC features a DJI optimized FOC algorithm to offer improved performance during rotor acceleration and deceleration. The gain values and power bandwidth must be

adjusted according to your ight control system and airframe.

The table below shows typical parameters when using the

E7000 with a DJI A3 ight control system, a quad-rotor frame

with a diagonal distance of 1200 mm, and at a takeoff weight of 28 kg:

4. Installation and Connection

Use a suitable airframe that can withstand the large

thrust delivered by the E7000 Propulsion System.

The powertrain includes a 40mm diameter carbon ber tube.

Mount the powertrain to an appropriate connector only.

Identify the clockwise and counter-clockwise marks

on the propellers and mount the powertrains onto the corresponding positions of the airframe.

When connecting cables to the frame’s power system, be

sure to select plugs and wires whose current is sufciently

rated the entire system.

1) Mount the powertrain onto the corresponding position of the

airframe. Rotate to ensure that the propeller is oriented upright,

then x it rmly.

2) Solder the red VCC cable and black GND cable of each

powertrain to the frame’s power system. Make sure that the solder points are strong and that there is no chance for a short circuit.

3) Connect the signal cable to your ight controller. The signal cable’s

red wire transmits the control signal; the black wire is for ground.

4) When using the powertrain together with the DJI N3, A3,

N3-AG or A3-AG flight controller, connect the data cable to the iESC port on the flight controller via the smart ESC communication cable for real-time communication with the

flight controller and redundant throttle signal transmission. Arrange the cable properly if not used, so that it will not interfere with other on-board devices.

5. Using DJI Assistant 2

The DJI ASSISTANTTM 2 is used to update the ESC rmware.※ Be sure to remove the propellers before using DJI Assistant 2.

Powertrain Updater Computer

Before using the Updater, unplug any other serial devices that are connected to your computer, then follow the instructions below:

1) Download and install DJI Assistant 2 from the official DJI

website. (http://www.dji.com/e7000/info#downloads)

2) Connect the Updater to the powertrain with the data cable

and to your computer with a Micro USB cable.

3) Connect a 12S LiPo battery to the powertrain to supply power

to the system. Do not disconnect the powertrain from the

computer or power supply until the conguration is complete.

4) Launch DJI Assistant 2. When a connection is established,

the software will display the connected devices.

5) Click under “Connected Devices” to enter the firmware

update page. Check the current rmware version and ensure the installed rmware is up to date. If not, login with your DJI

account and click the Upgrade button.

If your ESC is not recognized by DJI Assistant 2 (no connected devices):

Check if there is more than one FTDI device connected

such as another DJI Updater, an FTDI USB adapter or development board (e.g. a BeagleBone, Raspberry or Arduino board). Unplug the other FTDI devices, restart the ESC and DJI Assistant 2, and try again.

Re-connect the ESC and the power supply in the following

order: Connect the ESC to your computer, connect the power supply to the ESC, and then launch DJI Assistant 2.

When using the ESC together with the DJI N3 or A3 ight controller,

※

connect the data cable to the iESC port on the ight controller via

the smart ESC communication cable to update all the connected

ESCs’ rmware together in the ight controller page of DJI Assistant 2: Connect the ight controller to DJI Assistant 2 -> ight controller icon -> Firmware Update -> ESC Firmware List.

It can support short term operation (about 10 to 30 sec) with a current between 50 A and 85 A, and continuous operation with a current under 50 A. The motor run time should depend on the actual environmental temperature and cooling conditions.

9. FAQ

How do I replace the propeller blades or propeller adapters if they are damaged?

1) Prepare two propeller blade screws (M8×26 hex cap), four propeller adapter screws (M3×15 hex cap), and four propeller washers.

2) Apply threadlocker to the screw holes on the motor and the propeller adapter.

3) Assemble the propeller and tighten with two propeller blade screws (M8×26 hex cap) so that the blades can fold smoothly. Mount the propeller onto the motor and use four propeller adapter screws (M3×15 hex cap) to secure the propeller.

Propeller Blade Screws

(M8×26 Hex Cap)

Ensure the screw is secured tightly for the threadlocker

to be effective.

Ensure the threadlocker is completely dry and solid before

ight to prevent the propeller from ying off the motor.

- 效率，T- 扭矩，P- 输出功率，I- 电流，N- 转速

以上数据均为输入电压 44.4 V 时的理论值，仅供参考。在室温 25℃、无额外冷却装置的情况下，电流超过 85 A为不可工作区域，50 - 85 A 为短时（约 10 - 30 s）工作区域，50 A 以下为可持续工作区域。实际使用时，请根据工作环境温度和散热条件控制电机运行时间。

特征参数

速度常数 115 rpm/V 反电动势常数 * 0.0831 V·s/rad 机械时间常数 2.37 ms 电机转子惯量 512 kg·mm 转子总惯量（含桨） 7426 kg·mm 扭矩常数 * 0.091 N·m/A 线电感 ** 18.9 - 23.6 线电阻 35 mΩ 热时间常数 750 s

* 反电动势常数和扭矩常数在电机电流较大时会有所变化，以上数据主要适用于

20 A 以下工况。

** 线电感是在电流频率 1 kHz 的RLC 电路中测得，其值随转子位置周期性变化。

9. 常见问题

如何更换桨叶或桨夹？

1) 使用 2 颗桨叶螺丝（M8×26，外六角）、4 颗桨夹螺丝（M3×15，外六角）和 4 个螺旋桨垫片重新安装螺旋桨。

2) 在桨夹和电机上方的安装孔螺纹内使用螺丝胶。

3) 安装桨叶螺丝（M8×26，外六角）至桨叶被夹紧且可自由旋转，然

后安装 4 颗桨夹螺丝（M3×15，外六角）并拧紧。

桨叶螺丝

（M8×26，外六角）

确保拧紧螺丝。螺丝过松可能会导致螺丝胶无法完全干燥固化。务必在螺丝胶完全干燥固化后再进行飞行，否则可能导致射桨。
