Placed on the lower left side of the electronic compass 2, the fifth motor 35 is placed on the upper left side of the electronic compass, the first motor 31, the second The distance between the motor 32, the third motor 33, the fourth motor 34, and the fifth motor 35 to the geometric center of the electronic compass 2 is equal, if the first motor 31, the second motor 32, the third motor 33, the fourth motor 34, and the fifth The N poles of the motor 35 are all directed toward the electronic compass 2, and the magnetic influences generated by the first motor 31N pole, the second motor 32N pole, the third motor 33N pole, the fourth motor 34N pole, and the fifth motor 35N pole will cancel each other.

Similarly, if the S poles of the first motor 31, the second motor 32, the third motor 33, the fourth motor 34, and the fifth motor 35 are both directed toward the electronic compass 2, the first motor 31S pole and the second motor 32S pole at this time. The magnetic influences generated by the third motor 33S pole, the fourth motor 34S pole, and the fifth motor 35S pole will cancel each other out.

An improvement of the unmanned aerial vehicle according to the embodiment of the present invention may be as follows. Each side of the motor magnet having the same polarity is affixed with a label, and the label is oriented toward the electronic compass 2.

During the installation and production process, the existing motor can be purchased, and then the magnet polarity detection is performed on the motor. For example, after detecting the N pole of the motor, the label is pasted on the N pole side of the motor, so during the installation process, the staff It is possible to intuitively know the N-pole orientation of each motor. Similarly, if the S pole of the motor is detected, the label is attached to the S-pole side of the motor. Therefore, during the installation process, the staff can intuitively know the S pole of each motor. Orientation, that is, during the installation process, it is only necessary to control the label to be aligned with the electronic compass 2, so that each motor can be oriented toward the electronic compass 2 with the same polarity of the magnet, which can greatly avoid the modification of the motor. Increased installation efficiency.

The above is a preferred embodiment of the present invention, and it should be noted that those skilled in the art can also make several improvements and retouchings without departing from the principles of the present invention. It is the scope of protection of the present invention.
