Description

Stator for wind-driven generator
Technical field
The present invention relates to a kind of technology of motor field, specifically a kind of stator for wind-driven generator.
Background technique
Wind-driven generator is that one kind converts wind energy into mechanical work, and mechanical work drives rotor rotation, to export alternating current Power equipment.Inventionbroadly, wind energy is also solar energy, it is possible to say that wind-driven generator is one kind using the sun as heat source, with Atmosphere is the heat energy utilization generator of working media.The generating efficiency of traditional wind is low, and wind energy utilization is low, power generation effect Fruit is poor, and the low phenomenon of generating efficiency becomes apparent in low wind speeds.
Summary of the invention
The present invention In view of the above shortcomings of the prior art, proposes a kind of stator for wind-driven generator, especially needle Wind energy recycling to low wind speeds.
The present invention is achieved by the following technical solutions:
The present invention includes: stator core and winding wound on it, and stator core includes: ring part and multiple protrusions, In: the end of protrusion is connected with the inner surface of ring part.
The multiple U-shaped slots of the outer surface radial equipartition of the ring part, the U-shaped slot and protrusion are correspondingly arranged and axis Identical, each axis meets at the center of ring part, convenient for being evenly arranged winding.
The top of the protrusion is equipped with the cambered surface of indent, and the horizontal length of the cambered surface is greater than the end of protrusion, so as to around Group stablizes installation.
The cambered surface of multiple protrusions forms the inner hole for installing stator core, the center of the inner hole and ring part Center is overlapped.
In order to advanced optimize the generating efficiency in the case where low wind speed, the stator core outside diameter and stator iron The ratio of the diameter of bore of core is 3.3-4.3;The ratio of the thickness of the outside diameter and stator core of the stator core is 4.0-4.8;The ratio of the width of the width and ring part of the protrusion is 2.8-3.8.
Technical effect
Compared with prior art, the present invention passes through the dimensional parameters of the dependency structure of optimization generator unit stator component, so that Generating efficiency gets a promotion, especially in case of lower wind speeds.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of stator core of the invention;
In figure: 103 being ring part, 104 be protrusion, 105 be U-shaped slot, 106 be salient angle.
Specific embodiment

It is equipped with rotor in the stator core, the gap of the rotor and stator core is 4.3~8.2cm.
The pole embrace of the stator core is 2.6~3.1.
The ring part 103 is the hollow cylinder of three U-shaped slots 105 of radial equipartition.
The outer diameter of a circle of the ring part 103 is 103cm;The stator core with a thickness of 24cm;Described The ratio of the thickness of the outer diameter of a circle and stator core of ring part 103 is 4.3.
The U-shaped slot 105 is correspondingly arranged with protrusion 104 and axis is identical, and each axis meets at the center of ring part 103 Place.
The protrusion 104 is the cambered surface that top is in indent, and the end that the horizontal length of the cambered surface is greater than protrusion 104 is formed The salient angle 106 of top two sides.
The spacing of the adjacent protrusion 104 in a circumferential direction is 22~37cm.
The width of the end of the protrusion 104 is 24cm;The outer diameter of ring part 103 and the difference of internal diameter be 8cm;The ratio of the difference of the width of the end of the protrusion 104 and the outer diameter of ring part 103 and internal diameter is 3.1.
The inner hole of the cambered surface composition stator core of multiple protrusions 104, in the center of the inner hole and ring part 103 The heart is overlapped.
The outside diameter of the ring part 103 is 103cm;The diameter of the inner hole is 27cm;The ring part 103 outside diameter and the ratio of diameter of bore are 3.8.
Above-mentioned specific implementation can by those skilled in the art under the premise of without departing substantially from the principle of the invention and objective with difference Mode carry out local directed complete set to it, protection scope of the present invention is subject to claims and not by above-mentioned specific implementation institute Limit, each implementation within its scope is by the constraint of the present invention.
