Description
Technical Field
The invention relates to the technical field of permanent magnet generators, in particular to a permanent magnet generator driven by a driver and an installation method thereof.
Background
A permanent magnet generator is a generator that generates a magnetic field based on permanent magnet material. Compared with the traditional excitation type generator, the permanent magnet generator has the advantages of simple structure, small volume, no need of external excitation and the like, and is widely applied in a plurality of fields.
In order to enable the permanent magnet generator to stably operate and meet various working condition requirements, a driver is required to control parameters such as rotor rotation speed, power and the like. The driver is a device for controlling the operation of the motor by adjusting the current and voltage of the motor to achieve a desired operating state. The direction of the magnetic field of the permanent magnet generator is closely related to the position of the rotor, and the current and the voltage of the motor are adjusted according to the position of the rotor, so that the magnetic field is always matched with the position of the rotor, and efficient power generation is realized.
The drive needs to be able to control the current of the permanent magnet generator to maintain stable operation of the motor. By adopting the current control technology, the current of the motor can be monitored in real time, and the output power and the rotating speed of the generator can be controlled by adjusting the current and the phase. In order to adapt to different working conditions and load demands, the driver needs to be able to adjust the output power of the permanent magnet generator. The rotating speed of the rotor can be adjusted in real time according to the requirement by adopting a power adjusting technology, so that the required power output is realized, however, the existing permanent magnet generator controls the rotor shaft to rotate through the driver so as to enable the rotor to rotate, and larger kinetic energy is required to be consumed, so that the power generation efficiency is not facilitated.

the rotor is of a hollow structure, and a permanent magnet is arranged on the outer surface of the rotor; a supporting frame for reinforcement is arranged in the rotor;
the transmission assembly comprises a large gear fixedly arranged at one end of the rotor and a speed reducer connected with the large gear through small open teeth;
the ratio between the maximum outer diameter of the large gear and the maximum outer diameter of the rotor is (13-14): 8-9;

a steel plate is arranged at the fixed end of the rotor and the large gear, and a second reaming hole matched with the first reaming hole is formed in the steel plate; the first reaming hole is fixedly connected with the second reaming hole through a bolt.
The invention has the advantages that the driver is used for driving power generation, the angle operation between the large gear and the rotor is adopted while the speed is reduced and changed, the driving effect of the driver can be increased, the small tooth is used for poking the large gear, larger torque is generated while the speed is reduced, the distance from the edge of the rotor to the edge of the large gear is equivalent to a lever for saving power, and the purpose of saving electric energy is realized.
Further, the maximum outer diameter ratio of the large gear to the small open gear is (13-14): (2-3), and the tooth ratio of the large gear to the small open gear is (16-17): (2-3); the ratio of the thickness of the large gear to the length of the rotor is (1-1.5) (12-13).
The maximum outer diameter ratio and the tooth ratio of the large gear and the small gear are ensured through matching, so that an ideal transmission effect is achieved, the control proportion relation can enable power transmission to be more efficient, energy loss is reduced, and torque output efficiency is improved; the unbalanced moment during gear transmission can be reduced by reasonably selecting the maximum outer diameter and the tooth number ratio of the large gear and the small gear, so that the rotation of the rotor is more stable. This helps to reduce noise, vibration and mechanical wear and to extend the service life of the permanent magnet generator.
The ratio of the thickness of the large gear to the length of the rotor is reasonable, so that sufficient transmission strength is ensured, and larger output torque can be realized by matching the large gear with the small tooth and combining with the selection of the length and the thickness ratio of the rotor. With the same input power, a higher power output can be provided.
Further, the output end of the driver is fixedly connected with the input end of the speed reducer through a coupler.

The design can uniformly bear the weight and the rotation inertia of the rotor, and ensures the stable operation of the permanent magnet generator; the support frame can keep the rotor balanced in the rotating process, and the axial load is reduced. This helps prevent the rotor from rattling and twisting at high rotational speeds, reduces contact of the rotor with the stator, and suppresses the generation of vibration and noise.
Further, the connecting plate is annular; the surface of the large gear is circumferentially and uniformly provided with a plurality of arc grooves at intervals, and the ratio of the maximum outer diameter of the large gear to the inner diameter of the circular through groove to the width of the connecting plate is (13-14): (8-9): 2.
The shape of the connecting plate is annular, so that stronger structural support and stability can be provided; the arc-shaped groove can provide extra structural strength, so that the weight of the large gear can be reduced, and the energy consumption of the rotation of the large gear can be saved.
Further, one end of the rotor, which is fixed with the large gear, is provided with a steel plate, and the ratio of the inner diameter of the rotor to the inner diameter of the steel plate is (7-8) (6-6.5); the rotor is used for installing one end of the steel plate and the length of the other end of the steel plate is 10 cm.
The steel plate can assist in fixing the large gear and the rotor, provide additional support and rigidity for the rotor, improve the structural strength of the rotor, and facilitate the installation of the large gear by workers due to the fact that the length of one end of the rotor for installing the steel plate is 10 cm longer than that of the other end of the rotor.

Compared with the prior art, the invention has the beneficial effects that:
the invention uses the driver to drive the large gear to rotate the rotor through the transmission part, thereby reducing the speed and increasing the output torque. Meanwhile, the structure can also reduce the power consumption of the driving motor and achieve the purpose of saving electric energy. In general, direct drive rotors are required to overcome the high speed and high torque requirements, and therefore require significant power. By using a speed reducer to drive the rotor, sufficient torque can be obtained at low speed operation without excessive power input.
By the reduction effect, when the torque output by the driver is transmitted to the rotor through the pinion and the large gear, the rotor can obtain a larger output torque due to the effect of the reduction ratio. This provides a greater power output at the same input power. This configuration can provide a greater output torque with a corresponding reduction in the power required to drive the motor. Therefore, the load of the driving motor is reduced, and the power consumption is reduced, so that the use of electric energy is saved.
