Problems solved by technology

[0003] However, the heat dissipation of the above-mentioned brushless motor is only dissipated through natural heat radiation, and its heat dissipation efficiency is low, and it is easy to cause the motor magnet to fail due to high temperature
In addition, dust and other impurities in the environment can easily enter the motor through the open outer cover and cover the internal components of the motor. In severe cases, the motor will run poorly or even fail to run.

Embodiment Construction

[0077] see figure 1 , an unmanned aerial vehicle 500 according to an embodiment of the present invention, which is used to carry electronic devices (not shown) such as video cameras and cameras to take pictures. The unmanned aerial vehicle 500 includes an aircraft body 510 , a motor 100 disposed on the aircraft body 510 and a propeller 200 disposed on the motor 100 . The motor 100 is used to drive the propeller 200 to rotate, thereby driving the UAV 500 to fly.

[0078] Please also see Figure 2 to Figure 4 , the number of the motors 100 is multiple, and the multiple motors 100 are respectively arranged on the aircraft body 510 . In this embodiment, the motor 100 is a brushless motor, which includes a base 10, a stator 30 fixedly arranged on the base 10, a rotor 50 rotatably connected to the base 10, and a rotor 50 arranged on the rotor 50. The upper cover body 70 and the rotating shaft 90 disposed on the cover body 70 .

[0079] Please also see Figure 5 and Figure 6 ,...

Abstract

The invention relates to a motor, a power device and an aircraft using the power device. The aircraft comprises an aircraft body, a motor arranged on the aircraft body and propellers mounted on the motor, wherein the motor is formed by a stator arranged on the aircraft body, a rotor rotationally covering the stator and a cover body arranged on the rotor; the cover body has blades; and a slit is formed in the cover body. When the motor operates, the rotor drives the cover body to rotate; rotation of the blades enables air in the rotor to be discharged out of the slit and take away heat produced by the motor. The aircraft and the motor have high heat radiation efficiency and are dustproof.

Description

technical field [0001] The invention relates to a motor, a power device using the motor and an aircraft using the power device. Background technique [0002] Due to the advantages of low loss, low noise, smooth operation and long life, brushless motors are widely used in the field of mechatronics applications. Generally, a brushless motor includes a base, a stator set on the base, a rotor rotatably set on the stator, and an outer cover connected to the rotor. Usually, the outer cover is an open structure with large openings to facilitate heat dissipation of the motor, and the heat generated when the motor is running is radiated into the air through the open outer cover. [0003] However, the heat dissipation of the above-mentioned brushless motor is only dissipated through natural heat radiation, and its heat dissipation efficiency is low, which easily causes the motor magnet to fail due to high temperature. In addition, impurities such as dust in the environment can easil...
