Problems solved by technology

[0002] In order to meet the requirements of grid-connected power generation, high-power low-speed multi-pole generators such as wind turbines and hydroelectric generators need to output voltages of the same frequency at different speeds. Most direct drive generators now use rectification-inversion-frequency conversion Electronically adjust the output frequency by electronic means. Due to the complex structure, high failure rate and high cost of the inverter, it has become a major obstacle for wind power and hydropower generators to be connected to the grid for power generation.

Embodiment Construction

[0020] Such as figure 1 As shown, the speed-adjusting constant-frequency generator of the present invention includes a main shaft 1, a rotor fixedly installed on the main shaft 1, and a stator 3 surrounding the rotor, and the stator 3 is installed on the main shaft 1 through bearings. The rotor includes a claw pole plate 2, an iron core 51, and a rotor coil 5. The iron core 51 is fixedly installed between two opposing claw pole plates 2. The claw pole plate 2 is disc-shaped and made of a material with good magnetic permeability. Even pairs of tooth-shaped claw poles 21 are evenly distributed along the periphery of the peripheral portion thereof. The shape of the claw poles 21 is approximately trapezoidal. Such as figure 2 , image 3 As shown, two claw pole plates 2 are arranged relatively parallel in the form of staggered claw poles 21 . The claw pole plate 2 is fixedly installed on the main shaft 1 through the installation hole in its center, and a plurality of iron cores...

Abstract

The present invention relates to a speed governing frequency constant electricity generator that suitable for low speed multi-polar generator, which comprises a chief axis, a rotor fixedly mounted on the chief axis and a stator surrounds the rotor, wherein the stator is mounted on the chief axis through bearings; the rotor comprises claw pole plate, iron core and rotor coil, wherein the iron core is fixedly mounted between two claw pole plates that against each other; the claw pole plates are fixedly mounted on the chief axis through mounting holes in center; a plurality of iron cores are distributed around the chief axis evenly with rotor coil winding on them; the stator is in drum shape with one end of the drum wall fixedly connecting a shell cover; center of the shell cover is pluged on the chief axis through bearings; stator coil fixedly mounted on the inner side of the drum wall matches with the rotor coil; a terminal cap is mounted through bearings on the chief axis on the other side of the drum wall; the inside of the terminal cap is fixedly connected with a auxiliary stator, wherein the auxiliary stator comprises a auxiliary iron core and a auxiliary stator coil winding on the auxiliary iron core.

Description

technical field [0001] The invention relates to a generator, in particular to a speed-regulating constant-frequency generator suitable for low-speed multi-pole generators. Background technique [0002] In order to meet the requirements of grid-connected power generation, high-power low-speed multi-pole generators such as wind turbines and hydroelectric generators need to output voltages of the same frequency at different speeds. Most direct drive generators now use rectification-inversion-frequency conversion Electronically adjust the output frequency by electronic means. Due to the complex structure, high failure rate and high cost of the inverter, it has become a major obstacle for wind and hydro generators to be connected to the grid for power generation. Contents of the invention [0003] The purpose of the present invention is to provide a speed-regulating constant-frequency generator with simple structure, low speed, direct connection to the grid, and changing the sp...
