Problems solved by technology
Problems in the traditional mounting base: 1) The vibration of the outer rotor brushless motor is easy to loosen the bolt II, which may cause the outer rotor brushless motor to fall off; 2) The heat generated by the outer rotor brushless motor is not easy to dissipate, which is easy to cause The motor coil is burnt out; 3) To disassemble the outer rotor brushless motor, the bolt II must be removed first, which reduces the disassembly efficiency of the outer rotor brushless motor
[0005] The heat of the motor coil cannot be effectively dissipated, which usually affects the single operation time of the aircraft, and even burns out the coil, causing the aircraft to crash

Embodiment Construction
[0023] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.
[0024] Such as figure 1 As shown in , the outer rotor brushless motor 1 is connected to the traditional mounting base 4 through bolts Ⅰ5; figure 2 As shown, the traditional mounting base 4 is then connected to the aircraft main body 6 through bolts II7.
[0025] Such as image 3 As shown, the mounting base of the aircraft outer rotor brushless motor according to the present invention includes a base bottom plate 8 and a base outer ring 9 . There is a central big round hole 10, small round hole 11 and lightening hole 12 on the base bottom plate 8. There are cooling fins 13 on the outside of the base outer ring 9, and threads I14 on the inside that are opposite to the output torque of the rotor 2.
[0026] Such as Figure 4 As shown, use bolt I5 to pass through the small round hole 11 on the bottom plate of the base and sc...

The invention provides an installation base of an aircraft outer rotor brushless motor, and belongs to the technical field of aviation machinery. The installation base comprises a base bottom plate and a base outer ring. A large central circular hole, a small circular hole and a lightening hole are formed in the base bottom plate. Threads are arranged on the inner side of the base outer ring, and cooling fins are evenly distributed on the outer side of the base outer ring. One end of the installation base is connected with the outer rotor brushless motor through a bolt, and the other end of the installation base is connected with an aircraft body through threads. When the motor operates, the threaded connection can have a self-locking function. The installation base improves disassembly efficiency of the motor of a motor-driven aircraft, reduces the risk that a motor coil is burned out due to accumulated heat, and eliminates the hidden danger of falling off of the motor.
Description
technical field [0001] The invention discloses a mounting base for an aircraft outer rotor brushless motor, which belongs to the technical field of aviation machinery. Background technique [0002] The outer rotor brushless motor has large torque, high speed, low power consumption and low noise. Therefore, electric aircraft usually use external rotor brushless motors. Compared with aircraft powered by thermal engines, electric aircraft have less noise, are more concealed during military reconnaissance, and have higher survivability and mission success rate. Electric aircraft can be used in various fields such as military reconnaissance, environmental monitoring, emergency rescue and disaster relief. The mounting base is the connecting part between the motor and the main body of the aircraft, which is related to the success or failure of the design and use of the electric aircraft. [0003] Such as figure 1 with figure 2 As shown, the outer rotor brushless motor is conn...
