Problems solved by technology

However, the current existing generators, no matter large generators or small generators, have the problem of large starting resistance and difficulty in starting.
However, if the starting resistance of the generator is reduced to a large extent, it will cause damage to the generator and bring unsafe factors. Therefore, reducing the starting resistance of the generator to an appropriate range is the inventor's in-depth research. problem to be solved

Embodiment Construction

[0037] The invention discloses a generator system. Since the permanent magnet generator in the generator system adopts 6 stator slots on the inner wall of the stator, the 6 stator slots are evenly distributed along the inner circumference of the stator, and the rotor is 4 fan-shaped rare earth The ring-shaped rotor surrounded by permanent magnet steel, the rotor is fixedly sleeved on the rotating shaft, so that the starting resistance torque of the generator in the generator system is reduced by 15% compared with that of the generator in the prior art- 31%, so that the starting resistance of the generator in the generator system is reduced by an appropriate range, ensuring the performance and practical safety of the generator.

[0038] as the picture shows, figure 1It is a schematic diagram of the generator stator and rotor in the generator system of the present invention, including a stator 1, a rotor 3 and a rotating shaft 4, the stator 1 includes 6 stator slots 2, the stato...

Abstract

A generator system, including a control device, a generator drive mechanism and a generator, the control device triggers the generator drive structure to start and then starts the generator to generate electricity, wherein the generator is a permanent magnet generator, and the permanent magnet generator includes a stator, a stator Winding, rotor and shaft, the inner wall of the stator has 6 stator slots, the 6 stator slots are evenly distributed along the inner circumference of the stator, the rotor is a cylindrical rotor surrounded by 4 fan-shaped rare earth permanent magnet steels, and the rotor is fixedly sleeved on the shaft , the radius of the rotating shaft is adapted to the inner radius of the cylindrical rotor, so that the starting resistance of the generator of the generator system is reduced to an appropriate level, ensuring the performance and safety of the generator in the generator system.

Description

technical field [0001] The invention belongs to the technical field of generators, in particular to a generator system. Background technique [0002] A generator is a motor that converts mechanical energy into electrical energy. Usually driven by a steam turbine, water turbine or internal combustion engine. Electric energy is one of the most important energy sources in modern society. Generators are widely used in industrial and agricultural production, national defense, science and technology and daily life. And existing generator at present, no matter large-scale generator, or small-sized generator all has the problem that starting resistance is big, is difficult to start. However, if the starting resistance of the generator is reduced to a large extent, it will cause damage to the generator and bring unsafe factors. Therefore, reducing the starting resistance of the generator to an appropriate range is the inventor's in-depth research. The problem to be solved. Cont...
