Detailed Description
Embodiments of the invention are further described below with reference to the accompanying drawings:
examples
As shown in fig. 1 to 9, the generator 1 is provided, the generator 1 is connected with a regulator 2 and a rectifier 3, the rectifier 3 is connected with a load 4, a starter 5 and a storage battery 6, and the specific circuit connection is as shown in fig. 1.
In the embodiment, the generator is a claw pole brushless synchronous generator, and after two claw poles are positioned, a non-magnetic material is filled between the two claw poles and is welded with the claw poles. An armature winding of the generator 1 adopts a six-phase form with double Y phases with an electrical angle difference of 30 degrees; the present embodiment provides the double Y phase difference winding with 30 degrees, which is actually to divide each phase zone of the general 60-degree phase zone winding into two equal segments, and connect them into a star shape, thereby forming the form shown in fig. 2 and 7. Inside the motor, each pair of pole pitch of the inner circle of the stator is internally and equally divided into 12 phase bands, each phase band is 30 electrical degrees, so that the phase bands are windings which are spatially distributed for 30 degrees, and the two stars have 30 electrical degrees of difference, so that the phase bands are called double-Y30-degree-difference windings. As can be seen from fig. 2 and 7, this is an asymmetric 6-phase system in terms of induced electromotive force and a symmetric 12-phase system in terms of current and magnetomotive force.
The winding factor of a six-phase winding with double Y phases differing by 30 degrees in electrical angle is high. The narrower the phase band, the larger the distribution coefficient of the windings, and the six-phase winding with the double Y phase difference of 30 degrees in electrical angle actually divides the 60-degree phase band winding most commonly used in the alternating current motor into two windings, so that the distribution coefficient of the windings is improved. The 30 degree phase band winding can have a much larger short throw ratio than the 60 degree phase band winding and thus the short throw factor and hence the winding factor can be increased.
The six-phase winding slot current with the difference of 30 electrical degrees of double Y is reduced, and the electromagnetic force and the electromagnetic vibration applied to the winding are reduced. Because the three phases are changed into six phases, the phase current is reduced, the slot current is also reduced, the electromagnetic force and the electromagnetic vibration are reduced, and the running reliability of the motor is improved.
After three-phase symmetrical current is introduced into the 60-degree phase-belt winding, the synthetic magnetomotive force of the 60-degree phase-belt winding contains 6k +/-1 harmonics, k is a natural number, and the synthetic magnetomotive force of the six-phase winding with the double Y phase difference of 30 degrees in electric angle only contains 12k +/-1 harmonics under symmetrical load, namely the harmonics with the frequencies of 5, 7, 17, 19 … and the like are reduced. Thereby improving the operating performance of the motor.
The claw-pole synchronous generator is fixed by an excitation winding, the excitation winding and a rectifier are fixed on a stator, and only the structure form that a magnetic pole rotates is adopted. The excitation winding and the rectifier tube of the rectifier are radiated by the same radiator. The excitation winding adopts a solenoid form, and the generated magnetic field is driven by the rotating magnetic pole to become a rotating magnetic field to sweep across the armature winding to generate induced potential for electromechanical energy conversion. Therefore, the excitation winding is fixed, so that the excitation current can be directly connected with the excitation power supply without being introduced from the outside through the brush slip ring structure, and the reliability of the motor is greatly improved. Because the excitation winding is fixed, the manufacturing process of the excitation winding is simple, and a series of problems caused by high-speed rotation are not required to be considered.
The rectifier adopts six-phase full-wave rectification. The six-phase full-wave rectifier is formed by connecting two three-phase full-wave rectifiers in parallel, a positive module and a negative module which are insulated by diodes and a bottom plate are selected as the rectifier, and the six modules form the six-phase full-wave rectifier.
Since the diodes are insulated from the module base, the module can be mounted on the same circular heat sink with a centrifugal fan-cooled rectifier mounted in the center of the heat sink. Diode module as in fig. 8, two diodes P, N in the module are connected, six modules form a six-phase full-wave rectifier, and the diodes in the modules are insulated from the bottom plate. The rectifier module is mounted on a disc-shaped heat sink having axial and radial fins by a base plate, and a centrifugal fan is mounted in the middle of the heat sink.
Comparing fig. 3, fig. 4 and fig. 5, fig. 6, it can be seen through waveform analysis that the six-phase double-Y winding with an electrical angle difference of 30 degrees works in cooperation with the six-phase full-wave rectifier, and the peak-to-peak value of the rectified voltage waveform is greatly reduced compared with the three-phase winding with an electrical angle difference of 60 degrees and the three-phase full-wave rectifier, that is, the peak value of the output ripple voltage can be greatly reduced, and the requirement of electromagnetic compatibility is met. The peak value of ripple voltage of a common winding is about 4V, and the ripple voltage of the structure adopted by the scheme is less than 2V and is reduced by a half.
The voltage regulator adopts a digital form, and regulates the current of the excitation winding by detecting an output voltage signal so as to keep the output voltage stable. The digital form further improves the anti-interference capability of the system.
The claw-pole brushless synchronous generator, the rectifier and the voltage regulator are integrated into a power generation system, and the requirements of a high-power-density power generation system for reducing the size, lightening the weight, reducing harmonic waves and improving the stability are met on the basis of improving the power generation performance.
