Abstract
The utility model discloses a rotor structure of a low rotating-speed permanent-magnet synchronous generator. The rotor structure comprises a rotor yoke (1) and magnetic steels (2) arranged on the surface of the rotor yoke (1), wherein the surface of the rotor yoke (1) is provided with the 42-pole magnetic steels (2) uniformly distributed in pair of 'N'-pole and 'S'-pole; the magnetic poles of every two adjacent magnetic steels are oppositely distributed; and an aluminum plate (3) is closely fixed between every two adjacent magnetic steels on the rotor yoke (1). The rotor structure has reasonable structure and clear rotor magnetic circuit, and can improve the magnetic performance of the generator.
Description
Technical field
The utility model relates to a kind of electric machine structure, especially a kind of rotor structure of slow-speed of revolution magneto alternator.
Background technology
In order to alleviate contradiction between oil supply and demand, China develops regenerative resource rapidly.Domestic wind-power market has a high potential, and is in the high speed development stage.The wind power generation industry belongs to domestic emerging popular industry.Because wind power generation has factors such as environmental protection, low operating cost, the development of wind power generation is rapid now, rough estimates, the market capacity of wind power generation electric control system product in 2009 is between 20～2,500,000,000, expectation all will keep the growth rate more than 30% in recent years, so the market demand of small-sized wind power generator increases rapidly.At present, small-size wind power-generating mainly uses slow-speed of revolution magneto alternator, and its rotor structure is unreasonable, has influence on the further raising of motor electromagnetic performance.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of rational in infrastructure, magnetic circuit rotor structure of slow-speed of revolution magneto alternator clearly.
Technical problem to be solved in the utility model is achieved by the following technical solution: the magnet steel that it comprises rotor yoke and is located at the rotor yoke surface, be provided with by paired extremely equally distributed 42 utmost point magnet steel of " N " " S " on the surface of rotor yoke, every adjacent two magnet steel magnetic poles distribute on the contrary, be provided with the aluminium pressing plate and be fastened on the rotor yoke between adjacent two magnet steel.
The said structure that the utility model adopts, owing to be provided with by paired extremely equally distributed 42 utmost point magnet steel of " N " " S " on the surface of rotor yoke, rational in infrastructure, rotor magnetic circuit is clear, can improve the electromagnetic performance of motor.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Accompanying drawing is depicted as structural representation of the present utility model
Embodiment
By accompanying drawing as can be known, the magnet steel 2 that the utility model comprises rotor yoke 1 and is located at rotor yoke 1 surface, be provided with by paired extremely equally distributed 42 utmost point magnet steel 2 of " N " " S " on the surface of rotor yoke 1, every adjacent two magnet steel magnetic poles distribute on the contrary, be provided with aluminium pressing plate 3 and be fastened on the rotor yoke 1 between adjacent two magnet steel.Implementation of the present utility model: that the material of rotor yoke adopts is ZG200-400, finish in fine finishining, the magnet steel of design typification is performed the magnetic pole verification on the magnet steel frame, and identify clear, the surface of adopting anaerobic adhesive to stick on rotor yoke magnet steel forms magnetic pole, every adjacent two magnetic poles require opposite, and 42 utmost point magnet steel extremely evenly distribute by paired " N " " S ".Between two magnetic poles, the aluminium pressing plate is fastened on the rotor yoke, magnet steel is played pressuring action.The scope that the utility model is described the soverlay technique scheme, and the various variations of claim scope, any modification or improvement that those skilled in the art that the utility model is done realize easily all belong to the utility model scope required for protection.
