Abstract

The invention provides a connector of an electronic speed regulator and a motor. The connector of an electronic speed regulator and a motor comprises an output device (10) used for being electrically connected to three output terminals (31) of an electronic speed regulator (30), wherein the output device (10) comprises a first bearing portion (11) and three output connecting portions (12) used for respectively outputting three-phase driving signals of the motor, the three output connecting portions (12) are fixedly connected to be an integral body through the first bearing portion (11), so that relative positions of the three output connecting portions (12) are fixed; and an input device (20) used for being electrically connected to three input terminal (41) of the motor (40), wherein the input device (20) comprises a second bearing portion (21) and three input connecting portions (22) used for respectively inputting three-phase driving signals of the motor, the three input connecting portions (22) are fixedly connected to be an integral body through the second bearing portion (21), so that relative positions of the three input connecting portions (22) are fixed, and the three input connecting portions (22) are used for being respectively connected with the three output connecting portions (12) to electrically connect the input device (20) and the output device (10).

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...

Problems solved by technology

[0004] Because in the multi-rotor UAV, the rotation direction of the propeller is different, it is necessary to control the rotation direction of the DC brushless motor corresponding to different propellers; although the rotation direction of the DC brushless motor can be controlled by the three The connection order of each connector and the three interfaces of the electronic speed controller is determined. However, since the input of the brushless DC motor includes three connectors and the output of the electronic speed controller includes three interfaces, each motor is connected with the corresponding one. When connecting the electronic speed controller, you need to plug in the three connectors and the three interfaces respectively, and test whether the steering of the brushless DC motor is consistent with the preset steering of the motor. If not, you need to disassemble the three connectors currently connected Change the connection sequence after connecting with the interface, until the connection sequence of the three connectors and the three interfaces can make the electrode installation preset turn to rotate, it can be seen that the wiring operation is very cumbersome
