Embodiment 1

[0023] Example 1, please refer to Figure 1-4 The embodiment of the present invention provides a connector of an electronic speed governor and a motor, which includes an output device 10 and an input device 20.

[0024] The output device 10 is used to be electrically connected to the three output terminals 31 of the electronic governor 30 of the aircraft. The output device 10 includes a first carrying portion 11 and three outputs for respectively outputting three-phase drive signals of the motor 40 The connecting portion 12, the three output connecting portions 12 are fixedly connected into a whole through the first carrying portion 11, so that the relative positions of the three output connecting portions 12 are fixed.

[0025] The input device 20 is used to electrically connect to the three input terminals 41 of the motor 40 of the aircraft. The input device 20 includes a second supporting portion 21 and three input connecting portions 22 for respectively inputting three-phase d...

Embodiment 2

[0027] In the second embodiment, on the basis of the first embodiment, the input device 20 and the output device 10 are coaxially arranged, the three output connection parts 12 are arranged on the end surface of the output device 10, and the three input connections The portion 22 is arranged on the end face of the input device 20, the end face of the output device 10 is arranged opposite to the end face of the input device 20, and the input device 20 and the output device 10 are relatively coaxially rotated and preset After the included angle, the input device 20 can still be electrically connected to the output device 10 through the connections of the three output connection portions 12 and the three input connection portions 22, and the preset included angle is less than 360 degrees .

[0028] Among them, the three-phase drive signals of the motor 40 are A-phase drive signals, B-phase drive signals, and C-phase drive signals. Correspondingly, the three output terminals 31 of th...

Embodiment 3

[0030] In the third embodiment, on the basis of the second embodiment, the preset included angle is 180 degrees. Therefore, the connection state between the input device 20 and the output device 10 has only two situations, for example: before rotating, the input device 20 and the output device 10 The connection state of the device 10 is: A phase output connection part 12 is connected to A phase input connection part 22, B phase output connection part 12 is connected to B phase input connection part 22, C phase output connection part 12 and C phase input connection part 22 Connected, that is, the A-phase drive signal is input to the A-phase input terminal 41, the B-phase drive signal is input to the B-phase input terminal 41, and the C-phase drive signal is input to the C-phase input terminal 41; after rotating 180 degrees, the input device 20 and the output device 10 The connection state is: A phase output terminal 31 is connected to C phase input terminal 41, B phase output ter...

Description

Technical field [0001] The invention relates to connection equipment technology, in particular to a connector of an electronic speed governor and a motor, a power system and an unmanned aerial vehicle. Background technique [0002] The current UAV driving system uses a DC brushless motor and an electronic speed controller. The electronic speed controller controls the DC brushless motor to rotate with preset parameters (for example, speed, direction, etc.) to drive the propellers to move at the preset parameters together. [0003] The input end of the existing brushless DC motor is provided with three wires, and the end of each wire is provided with a connector, and the output end of the electronic speed controller is provided with three interfaces. The three connectors are respectively connected to the interfaces one by one. In order to realize the connection between the electronic speed controller and the DC brushless motor. [0004] Since in multi-rotor UAVs, the rotation directio...
