Abstract
A permanent magnet synchronization electric generator comprises an outer shell, a rotator and a stator, wherein the outer shell is equipped with a chamber, the stator is equipped on the inside of the outer shell, the rotator is equipped inside the chamber, the rotator comprises a shaft and a permanent magnet body, the number of the permanent magnet body is at least one couple, the permanent magnet body appears tile shaped which is fixedly equipped on the shaft, and the inner round circle of the stator is equipped with a straight dent or a slant dent. When the rotator rotates inside the stator, the stator coil cuts the magnet line of the rare earth permanent magnet materials on the rotator, thereby making the stator coil generate electric energy. Since adopting the rotator structure matched by the shaft and the tile shaped permanent magnet, the utility model has the advantages of big electric generating power, good wave shape, convenient voltage adjusting, simple structure, light weight, not easy damaging and convenient maintenance and the like, and the dent equipped on the outer shell can help for heat radiation.
Description
Technical field:
The utility model relates to a kind of generator, particularly a kind of synchronous generator made from rare earth permanent-magnetic material.
Background technology:
In the prior art, the rotor portion of generator is to produce magnetic field with magnet to make electromagnetic generator, but there is the manufacturing process complexity in it, the cost height, and volume is big, shortcomings such as Heavy Weight and energy consumption height.Now existing people adopts rare earth permanent-magnetic material to make permanent magnet generator.China's patent 92204162.8 discloses a kind of rare earth permanent-magnetic generator, it does not have excitation winding and carbon brush, though can alleviate constant weight, cut down the consumption of energy processed complex, because of adopting overall structure, be difficult for heat radiation, when working long hours, the rare earth material temperature rise is too high, have a strong impact on magnetic field stability, cost is also high.
Summary of the invention:
Technical problem to be solved in the utility model is: existing magnet electromagnetic generator manufacturing process complexity, and pressure regulation difficulty, cost height, volume is big, Heavy Weight and energy consumption height; Existing rare earth permanent-magnetic generator adopts overall structure, is difficult for heat radiation, cost height.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to provide a kind of magneto alternator, described this magneto alternator is made of shell, rotor and stator, be provided with cavity in the described shell, described stator is arranged on the inboard of described shell, described rotor is arranged in the described cavity, it is characterized in that: described rotor is made of axle and permanent magnet, the quantity of described permanent magnet is at least a pair of, and described permanent magnet is fixedly installed on the described axle.
Further, described axle and permanent magnet are fixed together by glue and screw.
Further, described permanent magnet is a watt shape, and closely cooperates with the circumference of described axle.
Further, on the inner periphery of described stator, be provided with straight trough, and the quantity of straight trough is 24.
Further, on the inner periphery of described stator, be provided with skewed slot, and the quantity of skewed slot is 24.
Operation principle of the present utility model: when rotor rotated in stator, the magnetic line of force of rare earth permanent-magnetic material on the stator coil cutting rotor produced an induced electromotive force in the stator coil thereby make, and this induced electromotive force is the electric energy that sends of generator just.
The utility model and prior art contrast, because adopt an axle and watt rotor structure that the shape permanent magnet matches, it is big to have a generated output, simple in structure, advantages such as in light weight, waveform is good, pressure regulation is convenient, not fragile and easy to maintenance, and the groove that is arranged on the shell can help heat radiation.
