Description

Wind-driven generator

Technical field

The utility model relates to a kind of generator, specifically is a kind of wind-driven generator.

Background technology

Wind power generation is the renewable resource that has large-scale development and Commercial Prospect most, and under the support of national policy and the background that is becoming tight energy supply day, the wind-powered electricity generation industry of China particularly wind power equipment manufacturing industry has obtained significant progress.Wind-driven generator is the power-equipment that wind energy is converted into mechanical energy; What it utilized is wind energy inexhaustible, nexhaustible in the Nature; Have no radiation generation and environmental pollution; And have spatter property, indissolubility, to plurality of advantages such as extra power no dependences, be to have one of alternative energy source of development prospect most.But generally more than 360Kg, volume height big, that cause wind-driven generator to be installed in tens meters waves big, unstable in the air when meeting high wind in the deadweight of wind-driven generator at present; Complete machine usefulness is not high, need wind speed to reach 2M/S (meter per second) generating of could turning round when above.

The utility model content

In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of the utility model is to provide a kind of wind-driven generator, and from heavy and light, volume is little, and the high aerial amplitude of oscillation is little.

In order to address the above problem, the utility model adopts following technical scheme: wind-driven generator, comprise the machine power input module, and it is characterized in that: comprise housing, stator, rotor and be used for the armature shaft that mechanical energy is imported;

Described rotor comprises rotor core main body and 14 Nd-Fe-B permanent magnets, and the rotor core main body is installed on the armature shaft, and said 14 Nd-Fe-B permanent magnets are uniformly distributed with on the outer circumference surface that is arranged on the rotor core main body and are screwed;

Said stator comprises stator core and slot liner, F level enamelled wire, groove contract; The utmost point groove of stator is 45 grooves and is the winding type of 3 * 15 grooves; The stator core of stator is fixed in the said housing;

The housing two ends are equipped with front end housing, rear end cap through bolt;

Said armature shaft rear end and front portion are provided with back support place, preceding support place respectively; Back support place is passed through a Bearing Installation on rear end cap; On front end housing, the front end of armature shaft passes front end housing and is used to install the machine power input module through a Bearing Installation in preceding support place.

Preferably: be provided with a plurality of holes vertically on the described rotor core main body.

The beneficial effect of the utility model is: it rotates slim and graceful, the work of under the initial wind speed that obtains 2m/s, can generating electricity.And the tip lengths of motor windings is shortened, save the use of copper material, and alleviate generator weight.Generator amature adopts Nd-Fe-B permanent magnet material and moulding mosaic technology, has improved the intensity of rotor, has also reduced the volume of generator.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is done further explanation:

Fig. 1 is the internal structure profile of the utility model embodiment,

Fig. 2 is the internal structure left profile figure of the utility model embodiment,
