Background technology
The petrol and diesel oil generating set has very long developing history, has gone through belt transmission, automatic voltage regulator adjusting excitation and three great stages of digital frequency conversion.Present the bulking value of petrol and diesel oil generating set reduces greatly, even has realized portability owing to adopt the permanent magnet generator and the digitial controller of high power density, and the quality of output electric energy has also had significantly raising before.Permanent magnet generator is the important component part of whole petrol and diesel oil generating set, and its volume, weight, efficient, torque ripple etc. are directly connected to portability, efficient and the noise level of whole machine set system.Therefore improve the performance of the permanent magnet generator in the unit, especially increase its power density to reduce volume, weight, improve its efficient, reducing its torque ripple is the key point of further improving petrol and diesel oil generating set performance with vibration and the noise level that reduces system.
The winding construction of the magneto alternator in the petrol and diesel oil generating set mostly adopts common centralized winding or conventional distributed winding.The end of common centralized winding is shorter, so the resistance of winding is less, and the copper loss of generator is less; And coiling is convenient, can adopt the automatic coil winding machine coiling, is easy to volume production.But the electromotive force first-harmonic winding factor of common centralized winding lower (generally having only 0.866), this has limited the power density of generator to a certain extent.The harmful effect (winding factor of 5,7 subharmonic is higher) that common concentrated winding also can't weaken in the electromotive force 5 times and 7 subharmonic bring can cause the pulsation of bigger cogging torque and additional torque.If the employing distributed winding, being aided with suitable short distance can greatly reduce high order when keeping the first-harmonic winding factor very high, the winding factor of 5,7 subharmonic especially, thus improve the sinusoidal degree of generator output voltage, and reduce torque pulsation.But the end of this winding is very long, and resistance is bigger, thereby causes copper loss height, the efficient of generator low.Under the situation that does not adopt processing modes such as the oblique utmost point or skewed slot, use the cogging torque of generator of this winding also very high.This winding is not easy to the mechanization rule owing to cross over several teeth, is difficult for volume production, and processing cost is higher.
Summary of the invention
Goal of the invention: the problem and shortage at above-mentioned prior art exists, the purpose of this invention is to provide a kind of modularization permanent-magnetism synchronous generator, this motor can solve shortcomings such as traditional magneto alternator cogging torque is big.Simultaneously, owing to adopt special centralized winding, this kind generator can improve the sinusoidal degree of output voltage waveforms greatly, reduces the generator copper loss, improves the power density of generator.
Technical scheme: for achieving the above object, technical scheme of the present invention is a kind of modularization permanent-magnetism synchronous generator, comprise rotor yoke, permanent magnet, threephase stator winding and stator core, wherein permanent magnet is mounted on the inner surface of rotor yoke equably, the sheet number of the stator gear ratio permanent magnet of stator core is many two, and available combination has 10 utmost points, 12 grooves, 16 utmost points, 18 grooves, 22 utmost points, 24 grooves ... by that analogy; Be coated with layer slot insulator on the described stator tooth, the threephase stator winding is outside layer slot insulator; The stator tooth of described stator core evenly is divided into six parts, and every phase winding occupies wherein relative two parts, on the groove of correspondence, is wound with the out-phase winding in six grooves between only adjacent two parts, the equal same phase winding of coiling in all the other grooves.
The structure of rotor yoke is an outer-rotor structure, and the order that mounts permanent magnet is that N-S replaces mutually.
The threephase stator winding is centralized, and an end of every phase winding links together, and the other end is drawn the electric output interface as generator.
This modularization permanent-magnetism synchronous generator also comprises the rotor axle sleeve that has keyway, and generator amature links to each other with the rotating shaft of petrol and diesel oil machine by this keyway, and fixes by keyway.
Beneficial effect: the present invention has following beneficial effect: at first, adopt outer-rotor structure, permanent magnet is mounted on the inner surface of rotor core, and the centrifugal force in the time of can utilizing the rotor high-speed rotation prevents that permanent magnet from flying ease and damaging.Compare with the mode of other fixed permanent magnet (driving dovetail groove etc. as on buried, the internal rotor), this kind method cost has that cost is low, the advantage of easy processing.Simultaneously, the stator openings of the permanent magnet generator of outer-rotor structure outwardly, the coil winding machine of being more convenient for rolls off the production line, and also is beneficial to simultaneously the rotor permanent magnet heat radiation.Secondly, owing to adopted special number of teeth groove to count fit system and winding configuration, this kind generator is compared with the centralized winding magneto alternator of tradition, have first-harmonic winding factor height, electricity/the harmonics of magnetic force content low, send the sinusoidal degree advantages of higher of voltage; Compare with distributed winding magneto alternator, have advantages such as winding overhang is short, resistance is little, copper loss is low.Simultaneously, special number of teeth groove number cooperates, and has also reduced the cogging torque of generator greatly, can improve the generating set traveling comfort.At last, this kind generator can be processed by sub-module, and this is significant when making heavy-duty generator.
