Abstract

The invention discloses a DC brushless self-driven rotor wing device on the basis of an integrated scheme for integrating rotor wings and electromagnetic drive. Mainly, a drive device is composed of an electromagnet (1) and a permanent magnet (2), a rotor wing device is composed of a rotary ring (4) and blades (5), a measuring device is composed of a position sensor (6), and a supporting device is composed of a support (3). An electromagnetic field is generated after the electromagnet (1) is powered on, the permanent magnet (2) is pushed to move, and therefore the rotary ring (4) and the blades (5) are driven to rotate, and lifting force or power is generated for the device when the blades (5) rotate and move; the supply voltage is changed, and then the strength of the magnetic field generated by the electromagnet (1) can be changed, then the rotating speed of the rotary ring (4) and the blades (5) is changed, and the magnitude of lifting force or power generated by the device is changed; the position sensor (6) can sense the real-time position or rotating speed of the rotary ring, signals are provided outwards, the external supply voltage is changed, and the rotating speed of the blades (5) is controlled.

Description

technical field [0001] The invention relates to a power device for aircraft such as a rotorcraft, an unmanned aerial vehicle, and an aerial intelligent robot, and in particular to a DC brushless self-driven rotor device. Background technique [0002] The rotor, also known as the propeller, is a power device used by multi-axis drones, model aircraft, rotorcraft and aerial intelligent robots. The existing rotors are all driven by motors, and the rotors are all cantilever beam structures, which cause large vibrations. The motor-rotor device is inconvenient to install; and the motor rotates at a high speed, and the rotor lacks protection. When the rotor falls off or breaks, it is easy to fly out and cause personal injury. Therefore, in order to ensure safe flight and avoid accidents, it is necessary to improve the structure of the existing motor-rotor device. Contents of the invention [0003] The purpose of the present invention is to provide a DC brushless self-driven roto...
