Abstract
Description
Technical Field
[0001] The present invention relates to the field of aviation motors, and in particular to an ultra-high voltage brushless motor. Background Art
[0002] The brushless motors currently used in drones are all low-voltage motors with high-current power loads. From the perspective of power efficiency, the greater the current, the greater the heat generated by the load, and the greater the useless power loss.
[0003] Structurally, the permanent magnets of the brushless motor serve as the magnetic poles of the rotor or stator, and the copper coils are wound on the silicon steel material as the control magnetic poles of the rotor or stator. These are high-density materials, and the weight is proportional to the power. As the power increases, the weight also increases structurally. In the aviation field, the heavier the weight, the lower the aviation load efficiency, especially for micro UAVs. Reducing one gram of aircraft weight is equivalent to the cost-effectiveness of one gram of gold. In comparison, this motor cannot meet higher efficiency requirements. Summary of the invention
[0004] The present invention provides an ultra-high voltage brushless aviation motor, which is characterized by comprising a permanent electric body electrode sheet, an electrode sheet, an insulating rotor, a rotating shaft, an insulating stator, and a machine base. A plurality of permanent electric body electrode sheets are arranged on the inner wall of the insulating rotor and pasted with high-temperature insulating silicone, and are arranged in a circular pattern at intervals. A plurality of electrode sheets are arranged on the outer ring of the insulating stator and pasted with high-temperature insulating silicone, and are arranged in a circular pattern at intervals. The same-charge electric field electrode sheets repel the same-charge permanent electric bodies, and the opposite-charge electric field electrode sheets attract the opposite-charge permanent electric body electrode sheets. The electric field energy of the insulating stator is converted into the kinetic energy of the insulating rotor.
[0005] The electrode sheet is provided with a positive electrode sheet and a negative electrode sheet electrically connected to a circuit for converting positive and negative voltages of multiple power supply inputs, and a triode is provided to control the change of positive and negative voltages.
[0006] The permanent electricity electrode sheet is made of dielectric material, and is charged with positive and negative charges via a high voltage device to obtain a single-charge permanent electricity electrode.
[0007] It is further configured that the inner hole of the cover at one end of the insulating rotor is passed through a rotating shaft for fixed connection, and the rotating shaft passes through an inner hole of the insulating stator and is rotatably connected with a retaining spring of a bearing hole of a machine base.
[0008] It is further configured that the screws pass through the insulating stator to be provided with a plurality of mounting holes and are screwed to be connected with the screw holes of the machine base.
[0009] The beneficial progress made by the existing brushless low-voltage motor is different from the working principle. From the electric power formula, we know that W=UI. Under the same power, the voltage increases and the current decreases proportionally. The smaller the overload current of the motor, the smaller the power loss. At the same time, the existing motor material is the electromagnetic core of silicon steel sheet and copper wire electromagnetic coil, as well as permanent magnet. The thin sheets of different permanent magnets and electrodes are light in weight. BRIEF DESCRIPTION OF THE DRAWINGS

The insulating stator (5) is an insulating, high-strength, lightweight composite material. The insulating stator (5) is provided with a sub-mounting hole (501) and a stator shaft hole (502). The electric field electrode sheets (2) with the same charge and the permanent electric body (1) with the same charge repel each other, and the electric field electrode sheets (2) with different charges and the permanent electric body electrode sheets (1) with different charges attract each other. The electric field energy of the insulating stator (5) is converted into kinetic energy of the insulating rotor (3).
[0021] Figure 3 As shown, the electrode sheet (2) is provided with a positive electrode sheet (201) and a negative electrode sheet (202) electrically connected to a circuit for converting positive and negative voltages of multiple power inputs, and a triode is provided to control the change of positive and negative voltages.

Figure 3 The control part S1 and S2 are configured as control electrodes electrically connected to a frequency-adjustable control module, and the high and low level switching frequencies control the collector and emitter conduction frequencies, thereby achieving frequency changes of the positive electrode sheet (201) and the negative electrode sheet (202).
[0022] The existing power supply voltage standard is divided into 1000 volts, which is the range of low-voltage brushless motors. 300 kV to 1000 kV is ultra-high voltage, and more than 1000 kV is ultra-high voltage. This voltage standard is applied to power grid transmission and has been widely used. The boost module can reach the range of ultra-high voltage and ultra-high voltage, and both ultra-high voltage and ultra-high voltage can supply power to the electrode.
[0023] Figure 5 As shown, the permanent body electrode sheet (1) is a dielectric material, and a single-charge permanent body electrode is obtained. Our common permanent magnets are made of composite neodymium iron boron dielectric materials. After passing through a charging magnetic field, a stable magnet is formed. Similarly, the common dielectric of permanent bodies is rosin, palm wax, and beeswax as raw materials. After passing through a high-voltage positive and negative charge device and a charging field, a stable single permanent body is formed, a negatively charged permanent body (101) or a positively charged permanent body (102).

[0025] Working process and principle control; Common power sources for low-voltage brushless motors are two-phase, three-phase, and four-phase, which are determined by the different winding methods of the stator coils inside. Similarly, the charge electrode spacing of high-voltage brushless motors is different, and the power supply can be two-phase, three-phase, or four-phase control connected in series, or in series. The power supply control method is to convert the electrodes of the transistor. Low-voltage brushless motors use the repulsion and adsorption force of the permanent magnetic field to complete the conversion of electrical energy into kinetic energy, while high-voltage brushless motors use the repulsion and adsorption force of the permanent electric field to complete the conversion of electrical energy into kinetic energy. Under the premise that the power of the two is the same, the current of the high-voltage brushless motor is low, the loss of overload current is very small, and the temperature is low, thereby achieving energy saving.
